Guide to Selecting the Best Triathlon Wear

Getting the right triathlon wear can make all the difference when you’re training or racing. The good news is, you don’t need a separate outfit for swimming, cycling, and running. That’s what triathlon wear is for. It’s designed to handle every part of race day without needing a change of gear in between.

What really matters is how your gear fits and feels. It should help you move easily, without rubbing or riding up, and still keep you comfortable from start to finish. If you’re wondering what to look for, especially as winter training starts up, we’ve put together a few simple ways to pick gear that suits both the season and how you train.

Know What Makes Triathlon Wear Different

Triathlon wear stands out because it's built to stay with you through the swim, bike, and run. You can wear it under a wetsuit in the water, hop on the bike without stopping to change, and head into your run without missing a beat.

• Most pieces are made with quick-drying fabrics, so you’re not stuck feeling soggy after the swim
• A snug fit helps cut drag in the water and stops the fabric flapping on the bike or during the run
  • Fewer seams mean less chance of sore spots by the time you hit mile 10

The most common types include tri suits, which are full-body one-pieces, and separates like tri tops and tri shorts. Some swimmers prefer swimsuits under a wetsuit and add gear later, but suits made for all three sports tend to be more practical. They save time and help you concentrate on your effort, not your gear.

ZONE3’s Activate, Lava, and Aeroforce-X ranges offer a wide variety of quick-drying, ergonomically designed tri suits and separates to match different distances and skill levels, as featured on the ZONE3 website and in race-day gear guides.

Focus on Fit and Comfort

Good triathlon wear should fit like a second skin, but not so tight that you can’t breathe or move freely. When you try on a suit or top, flex a bit. Squat, swing your arms, take a deep breath. A good sign is if the fabric stays in place and doesn’t pinch.

• Stretchy fabric should bounce back instead of sagging or bunching
• Flat seams help prevent rubbing on longer races or intense training days
• Wide leg grippers or arm bands stop the gear from riding up, which can be helpful on the bike or run

It’s worth trying on different sizes if you’re unsure. A slightly tighter fit often feels better in the water but shouldn't cut into your skin. Comfort counts during training too, not just when you’re racing.

The ZONE3 Aeroforce-X and Activate tri suits feature bonded seams, silicon grippers, and premium stretch panels for a secure fit, as seen in product reviews on zone3.com.

Plan for Seasonal Training and Racing

Most triathlon races are held in warmer weather, but that doesn’t mean training takes a break when the temperature drops. As we move through January here in the UK, cold weather calls for some smart layering and small adjustments to your training kit.

• Add thermal base layers underneath your top or suit, especially during long outdoor sessions
• Arm warmers or leg warmers are easy to take off as you warm up, without needing a full outfit change
• For indoor training, skip the thermal gear but stick with breathable, snug clothing that wicks moisture

Winter often brings more pool workouts, turbo sessions inside, and shorter outdoor rides when conditions allow. It helps if your gear can adapt. Choosing flexible pieces gives you more options without buying a whole different set of clothes just for one season.

The ZONE3 Lava short sleeve tri suit features quick-drying and temperature-regulating Italian fabrics, designed for both summer races and winter indoor workouts.

Choose Based on Your Race Goals and Experience

Not all triathlon wear is the same, and what you need might depend on how long you’ve been training or how serious your race plans are. If you’re newer to the sport, comfort and coverage are probably more useful than having the lightest, fastest piece of kit.

• Beginners might prefer looser items with wider straps or higher necklines for peace of mind
• Experienced triathletes may look for lighter-weight options with fewer seams to save time on long races
• Think about how long your sessions run, if you’re training for hours, you want gear that can keep up the whole way

Whether you’re in the early stages or looking to shave a few seconds off your pace, the right gear can give you a solid base to build on.

Look After Your Kit So It Lasts Longer

Triathlon wear sees a lot, chlorine in the pool, salt in open water, mud on training rides. A few simple habits can keep it working well across training seasons.

• Rinse gear in cool water after every swim or sweaty workout
• Let it air dry flat, away from radiators or direct sun, so the fabric keeps its shape and stretch
• Rotate your clothing if you train several times a week, so no single piece wears out too fast

If the fabric starts thinning or doesn’t dry quickly anymore, that’s a sign it might be time to replace it. Stretched-out fits can feel fine when dry but will sag once wet, which is something to avoid during a race.

ZONE3 recommends rinsing their tri suits after each session and air-drying them out of the sun, to extend garment life and maintain fit across the seasons.

Find What Works Best for You

The best gear is the gear you forget you're wearing. It should feel like part of you, moving with you through the pool, on the bike, and into your run. That comes from a good fit, the right fabric, and choices that match how and where you train.

As winter routines set in, there's still time to line up what you'll wear this spring. Training through the colder months with gear that keeps you comfortable clears the way for a sharper focus when race season kicks back in. The better your gear suits your body and your training habits, the easier it is to train with focus and confidence.
