Sprint to Ironman experience with 50+ open water swims
I've raced in wetsuits across a wide range of water temperatures and conditions, from 55F early-season lake swims to wetsuit-optional races in warmer waters. This guide combines personal experience with research into materials science, hydrodynamics, and the latest developments from leading wetsuit manufacturers.
Every recommendation here is based on real-world performance, value for money, and suitability for different skill levels. Whether you're doing your first sprint triathlon or training for an Ironman, there's a wetsuit in this guide that's right for you.
Why You Need a Triathlon Wetsuit
A triathlon wetsuit is one of the most significant performance upgrades you can make to your swim. Unlike a bike or running shoes where gains are marginal, a wetsuit delivers substantial, measurable improvements for swimmers of all abilities.
Performance Benefits
- 5-10% faster swim times - from improved body position and reduced drag
- Better body position - buoyancy lifts hips and legs for horizontal swimming
- Reduced drag - smooth neoprene surface glides through water
- Energy conservation - less effort to maintain position saves energy for bike and run
- Increased stroke rate - some studies show 2-4% higher cadence
Comfort & Safety Benefits
- Warmth - maintain core temperature in cold water
- Buoyancy - added flotation builds confidence in open water
- Sun protection - coverage protects from UV exposure
- Chafing reduction - smooth interior prevents skin irritation
- Visibility - bright colors make you easier to spot
The Bottom Line
Even a budget triathlon wetsuit will make you significantly faster than swimming without one. For a 25-minute Olympic distance swim (1500m), a wetsuit typically saves 1:30-2:30. For an Ironman swim (3.8km), savings can be 4-7 minutes. This is "free speed" that requires no fitness improvement.
Sleeveless vs Full Sleeve Wetsuits
This is the most important decision when choosing a triathlon wetsuit. Both styles have distinct advantages, and the right choice depends on your swimming ability, typical water temperatures, and personal preferences.
Full Sleeve Wetsuits
Advantages
- + Maximum buoyancy and warmth
- + 1-3 seconds per 100m faster than sleeveless
- + Better for less efficient swimmers
- + More drag reduction on arms
- + Essential for cold water (<65F/18C)
Disadvantages
- - Can restrict shoulder movement
- - Warmer in hot conditions
- - Slightly slower T1 removal
- - May cause shoulder fatigue on long swims
Best For: Cold water, less experienced swimmers, maximizing speed
Sleeveless Wetsuits
Advantages
- + Complete shoulder freedom
- + Cooler in warm water (68-76F/20-24C)
- + Faster T1 transitions
- + Better for swimmers with high stroke rates
- + More natural swimming feel
Disadvantages
- - Less overall buoyancy
- - No arm drag reduction
- - Less warmth for cold water
- - Slightly slower for most swimmers
Best For: Warm water, strong swimmers, those who prioritize feel
Our Recommendation
For most first-time buyers, choose a full sleeve wetsuit. The additional buoyancy and speed benefits outweigh the minor restriction in shoulder movement, especially if you're not a competitive swimmer. Modern premium wetsuits have extremely flexible shoulder panels that minimize any movement issues. Only choose sleeveless if you're racing primarily in warm water (above 68F/20C) or have elite-level swim technique.
Wetsuit Thickness and Buoyancy Guide
Unlike surfing wetsuits that use uniform thickness throughout, triathlon wetsuits use strategic variable thickness to optimize both buoyancy and flexibility. Understanding this helps you choose the right suit for your needs.
Typical Triathlon Wetsuit Thickness Distribution
Chest & Core
Maximum buoyancy where you need lift most
Hips & Legs
Lift for horizontal position, some flexibility
Arms & Shoulders
Maximum flexibility for unrestricted strokes
How Buoyancy Panels Work
The key to a fast swim is maintaining a horizontal body position with minimal drag. Most swimmers' hips and legs naturally sink, creating drag. Triathlon wetsuits solve this by placing thicker, more buoyant neoprene in strategic locations:
- Core buoyancy (5mm): Lifts your torso to reduce frontal area
- Hip buoyancy (4mm): Prevents hip drop, keeping legs near the surface
- Thigh panels (3-4mm): Additional lift for sinky-leg swimmers
- Catch panels (2mm): Textured areas that grip water during the pull phase
For Weak Swimmers or Sinky Legs
If you struggle with body position or your legs drop significantly, look for wetsuits with enhanced buoyancy panels in the hips and thighs. The Orca Athlex Float and Zone3 Vanquish are specifically designed with extra lift for swimmers who need more help maintaining horizontal position.
Water Temperature Guidelines
Knowing when wetsuits are allowed, recommended, or prohibited is essential for race planning. Here's a comprehensive guide to water temperature rules and recommendations:
| Temperature | Status | Recommendation |
|---|---|---|
| Below 57F / 14C | Mandatory | Wetsuit required for safety. Consider neoprene cap and gloves. |
| 57-64F / 14-18C | Mandatory (most races) | Full sleeve recommended. Train in similar temps before race. |
| 64-68F / 18-20C | Allowed | Full sleeve ideal for most swimmers. Sleeveless possible. |
| 68-76F / 20-24C | Optional (age group) | Personal preference. Sleeveless good option for warmth management. |
| Above 76F / 24C | Prohibited (age group) | No wetsuits allowed. Swim skin recommended for some drag reduction. |
| Above 84F / 29C | Swim cancelled | Most organizations cancel or modify swim at extreme temps. |
USAT Rules (USA Triathlon)
- Wetsuits legal: Below 78F / 25.5C
- No wetsuits: 78F+ (age group)
- Pros: No wetsuits above 68F / 20C
World Triathlon Rules
- Age group wetsuits: Below 22C / 71.6F
- Elite wetsuits: Below 20C / 68F
- Mandatory: Below 14C / 57.2F
Fit Guide and Sizing
Proper wetsuit fit is crucial for both performance and comfort. An ill-fitting wetsuit can actually slow you down and cause discomfort. Here's how to ensure you get the right size:
Signs of Correct Fit
- Snug throughout: Like a second skin with no air pockets
- No excess material: Smooth against body at all points
- Neck sits properly: Snug but not choking, no gapping
- Shoulders unrestricted: Full range of motion for swimming strokes
- Lower back sealed: No water pooling or loose material
- Crotch in position: Not pulling down or sitting too high
- Wrists/ankles sealed: Snug cuffs prevent flushing
- Comfortable breathing: Not too tight across chest
Signs of Poor Fit
Too Big
- - Can pull suit 1+ inches from body
- - Water pools in lower back
- - Excess material bunches at joints
- - Flushing at neck/wrists/ankles
Too Small
- - Difficult to breathe deeply
- - Shoulders feel restricted
- - Can't fully extend arms overhead
- - Crotch pulls uncomfortably
Sizing Tips
- Use the brand's size chart: Sizing varies significantly between brands. Always check measurements.
- Height vs weight: If between sizes, prioritize height for full sleeve, weight for sleeveless.
- Body type matters: Broad shoulders? Size up. Long torso? Check torso length specs.
- Expect initial tightness: New neoprene stretches 10-15% with use. A slightly tight suit breaks in.
- Try before you buy: If possible, test fit in store or buy from retailers with good return policies.
Pro Tip: The Simulation Test
When trying on a wetsuit, simulate swimming motions. Reach arms fully overhead, rotate through a swimming stroke, and bend at the waist. Any restriction or discomfort will be amplified over a long swim. The suit should feel snug but never limit your movement.

Wetsuit vs No Wetsuit: Speed Difference
One of the most common questions is "how much faster will a wetsuit make me?" The answer depends on your swimming ability, but the data is clear: wetsuits provide significant speed benefits for all swimmers.
Typical Time Savings by Distance
| Distance | Weak Swimmer | Average Swimmer | Strong Swimmer |
|---|---|---|---|
| Sprint (750m) | 45-75 sec | 30-50 sec | 15-30 sec |
| Olympic (1500m) | 1:30-2:30 | 1:00-1:45 | 30-60 sec |
| 70.3 (1900m) | 2:00-3:00 | 1:30-2:15 | 45-90 sec |
| Ironman (3800m) | 4:00-6:00 | 3:00-4:30 | 1:30-3:00 |
Why Wetsuits Make You Faster
1. Body Position
Buoyancy lifts your hips and legs, reducing frontal drag by 10-15%. This is the biggest factor for slower swimmers.
2. Surface Friction
Smooth neoprene and SCS coatings create less drag than skin, saving 2-4% at race pace.
3. Energy Conservation
Less effort maintaining position means more energy for the kick and pull, improving efficiency throughout.
Premium vs Entry-Level Wetsuit Speed Difference
Studies and anecdotal evidence suggest premium wetsuits ($600+) are 2-4 seconds per 100m faster than entry-level suits due to better neoprene, coatings, and buoyancy distribution. Over an Ironman swim, this could mean 60-90 seconds difference between a $300 and $800 wetsuit.
Care and Maintenance
A well-maintained wetsuit lasts 4-6 years. Poor care can destroy a wetsuit in a single season. Follow these guidelines to protect your investment:
Do
- Rinse after every use with fresh, cool water
- Hang inside-out on a wide hanger to dry
- Store flat or on wide hanger away from sunlight
- Use wetsuit shampoo monthly to maintain neoprene
- Apply wetsuit lubricant to zippers periodically
- Use plastic bags on feet when putting on
- Apply anti-chafe products (Body Glide) at neck/wrists
- Dry completely before storing
Don't
- Never use hot water - damages neoprene
- Never machine wash or tumble dry
- Never use bleach or harsh detergents
- Never hang on wire hangers - causes creases
- Never fold for storage - creates permanent creases
- Never leave in direct sunlight - UV degrades neoprene
- Never pull by the neck when removing
- Never store wet - promotes mold growth
Monthly Maintenance Routine
- Fill bathtub with cool water and add wetsuit-specific shampoo
- Turn wetsuit inside out and submerge for 15-20 minutes
- Gently agitate water to clean - never scrub or twist
- Drain and refill with clean water to rinse
- Hang inside-out on wide hanger in shade to dry
- Once dry, flip right-side-out and apply zipper lubricant
- Store flat or hang in cool, dark location
Repairing Small Tears
Small nicks and tears are repairable with neoprene cement (available at dive shops). Clean the area, apply a thin layer of cement to both surfaces, let become tacky, press together firmly, and allow 24 hours to cure before use. For larger tears or seam failures, contact the manufacturer for professional repair.
Frequently Asked Questions
What is the best triathlon wetsuit for beginners?
The Blueseventy Sprint Fullsuit ($285-295) is our top recommendation for beginners. It offers excellent buoyancy, flexible shoulders for unrestricted swimming, and forgiving sizing at an accessible price point. The Yamamoto #39 neoprene provides quality typically found in $400+ suits. The TYR Hurricane CAT1 ($300) is another excellent entry-level option.
Should I get a sleeveless or full sleeve triathlon wetsuit?
For most triathletes, especially beginners and intermediate swimmers, a full sleeve wetsuit is the better choice. Full sleeves provide more buoyancy, warmth, and are typically 1-3 seconds per 100m faster. Only choose sleeveless if you primarily race in warm water (above 68F/20C) or have elite-level swim technique with a high stroke rate.
What thickness should my triathlon wetsuit be?
Triathlon wetsuits use variable thickness: 5mm in the chest and core for maximum buoyancy, 3-4mm in the legs for lift, and 1.5-2mm in the arms and shoulders for flexibility. This distribution optimizes both buoyancy and range of motion for horizontal swimming. The total thickness matters less than the strategic placement.
How much faster does a wetsuit make you swim?
A quality triathlon wetsuit can make you 5-10% faster. For a 1500m Olympic distance swim, this could save 1:00-2:30. For an Ironman 3.8km swim, the time savings can be 3-6 minutes. The speed gain comes from improved buoyancy, reduced drag, and energy conservation.
How tight should a triathlon wetsuit fit?
A triathlon wetsuit should fit snugly like a second skin with no air pockets or loose material. You should be able to move your arms through a full swimming stroke without restriction. Some tightness is normal when new - neoprene stretches 10-15% with use. If you can easily pull the suit away from your body by more than an inch, it's too big.
What is Yamamoto neoprene and why does it matter?
Yamamoto is a Japanese manufacturer of premium limestone-based neoprene. Their neoprene cells are smaller and more uniform than petroleum-based alternatives, making the material lighter, more buoyant, more flexible, and more durable. Yamamoto grades include #38, #39, #40, and #45 - higher numbers indicate more closed cells and better performance.
Can I use a surfing wetsuit for triathlon?
While technically possible, surfing wetsuits are not recommended for triathlon. Triathlon wetsuits are designed for horizontal swimming with strategic buoyancy panels and flexible shoulders. Surfing wetsuits are designed for vertical movement with uniform thickness. You'll be significantly slower and less comfortable in a surf suit.
How do I put on and take off a wetsuit quickly?
To put on: Use plastic bags on feet to slide through legs, pull up in small increments avoiding fingernails, use Body Glide on neck/wrists/ankles. To remove in T1: Unzip while running, pull arms out one at a time, push down past hips, step on suit with one foot while pulling other leg out. Practice regularly - good technique saves 30-60 seconds.
What's the difference between entry-level and premium wetsuits?
Entry-level wetsuits ($200-350) use standard neoprene and basic coatings. Premium wetsuits ($600-900+) use Yamamoto neoprene, SCS nano coatings for less drag, more strategic buoyancy panels, and superior flexibility. Premium suits are typically 2-4 seconds per 100m faster and more comfortable for long swims.
Should I buy or rent a triathlon wetsuit?
If you're doing 2+ triathlons per year, buying makes financial sense. Rentals cost $40-80 per race, so a $300 entry-level suit pays for itself in 4-8 rentals. Buying also lets you practice with your suit and ensure proper fit. However, renting is smart for your first triathlon to confirm you enjoy the sport.
How long does a triathlon wetsuit last?
With proper care, a quality triathlon wetsuit lasts 4-6 years or approximately 200-300 uses. Signs it needs replacement include: loss of buoyancy, permanent compression of neoprene, cracking or flaking of coatings, persistent water entry, or significant tears that can't be repaired. Racing wetsuits used only for competitions last longer than training suits.
What accessories do I need with my wetsuit?
Essential accessories include: Body Glide or Trislide (anti-chafe for neck and wrists), wetsuit-specific shampoo, a wide hanger for drying, and goggles. Optional but helpful: neoprene cap for cold water, wetsuit bag for transport, plastic bags for easy donning, and zipper lubricant for maintenance.
Our Final Recommendation
For most first-time triathlon wetsuit buyers, we recommend the Blueseventy Sprint Fullsuit. It offers exceptional value with Yamamoto neoprene quality at an entry-level price, providing the buoyancy and speed benefits you need without breaking the bank. As you progress in the sport and identify your specific needs (warmer water racing, maximum performance, etc.), you can upgrade to more specialized suits.
