Raceskin RS 01 vs RS 02: Which Open-Water Wetsuit Should You Race In?

Raceskin RS 01 vs RS 02: Which Open-Water Wetsuit Should You Race In?

Your wetsuit is the first piece of kit you trust on race morning. It decides how hard the swim feels, how fast you exit the water, and how fresh your legs are for the bike. Raceskin builds two open-water wetsuit lines for exactly that moment - the RS 01 and the RS 02 - and they are not aimed at the same swimmer. Here is the straight comparison, so you can pick a size and get race ready in one sitting.

THE TWO LINES, SIDE BY SIDE

RS 01 - THE OPEN-WATER ENTRY POINT

The RS 01 is a full-length open-water wetsuit built for buoyancy and dependable race-day performance. It is the wetsuit we hand to a first-time open-water swimmer, a club member stepping up from pool training, or anyone who wants a reliable suit without paying for features they will not use.

RS 02 - THE RACE-DAY STEP UP

The RS 02 is our performance line, and it is where the spec sheet gets serious: Airprene for up to 30% more buoyancy, SCS coating for reduced surface drag, varying panel thickness for flexibility, 1.5mm shoulder panels, taped seams at high-stress points, flatlock construction and a heavy-duty YKK reverse zip. It is built for the swimmer chasing a personal best, not just a finish line.

BUOYANCY: HOW MUCH LIFT DO YOU NEED?

Buoyancy does two jobs: it keeps your hips high so you swim flat, and it saves the energy you would otherwise burn keeping your legs up.

The RS 01 delivers a confident, stable float that suits most age-group swimmers. If your goal is a controlled, comfortable swim, it has everything you need.

The RS 02 changes the math with Airprene, which lifts roughly 30% more than standard neoprene. For swimmers who sit low in the water - heavier athletes, or anyone whose legs sink without a wetsuit - that extra flotation is not marketing. It translates directly into a flatter body position and less energy spent fighting your own buoyancy.

SHOULDER FLEXIBILITY AND STROKE FREEDOM

Shoulder fatigue is where open-water swims unravel. The more resistance the suit puts on your reach, the shorter your stroke gets by the second half.

Both lines use varying neoprene thickness to keep the core warm while freeing the arms. The RS 02 pushes this further with dedicated 1.5mm shoulder panels, so your catch and recovery stay loose over a long, cold swim. If you train with a high-elbow, long-stroke freestyle and want to keep it for the full distance, that shoulder construction is the difference you will feel on the first 200 meters.

SEAM CONSTRUCTION AND DURABILITY

Cheap wetsuits fail at the seams - usually right when you are pulling the suit off in transition.

  • RS 01: reinforced construction built to handle regular open-water training and racing season after season.
  • RS 02: taped seams at high-stress areas plus smooth flatlock construction, then finished with a heavy-duty YKK reverse zip that resists the salt, sand and repeated tugging that kill flimsier zips.

If you swim multiple times a week and race through a full season, the RS 02's seam work pays for itself in suit life alone.

FIT AND SIZING: MEN'S AND WOMEN'S CUTS

Both lines are cut for real swimmers, not generic neoprene blocks.

Sizing is the number one reason wetsuits get returned. Use the size chart, check shoulder girth first, and remember a race fit feels tight the first time you put it on. It loosens the moment you are in the water.

PRICE AND VALUE: WHAT YOU GET FOR THE STEP UP

The RS 01 sits at the accessible end of our range - a full open-water suit with the buoyancy and build quality to race now.

The RS 02 costs more, and the money goes somewhere concrete: more buoyancy, less drag, better shoulder freedom and tougher seams. Measured against premium race suits from the big brands, both lines sit in the mid-range and both are usually stocked, so you are not waiting on a backorder two weeks before your event.

CHOOSE THIS IF... - THE QUICK VERDICT

CHOOSE THE RS 01 IF:

  • You are racing your first open-water triathlon or event and how quick you swim is not your top priority.
  • You want reliable buoyancy and comfort at the best value.
  • You train in open water occasionally and race a few times a season.

CHOOSE THE RS 02 IF:

  • You are chasing a personal best and want every advantage in the water.
  • You sit low in the water and want maximum buoyancy.
  • You swim long distances and need shoulders that stay loose.
  • You race and train through a full season and want the suit to last.

GET RACE READY

There is no wrong answer here - only a suit that matches your goals. New to open water, the RS 01 gets you racing with confidence from day one. Targeting a time, the RS 02 is the edge you are looking for.

Pair either with a brightly branded RS Swim Cap for visibility in the pack, and check your size before race week. ONE BRAND. THREE DISCIPLINES. STOCKED AND READY TO RACE.
