Ask a triathlete about wetsuit care and you'll hear the same answer nearly every time: rinse it after the swim, maybe run a neoprene cleaner through it after a muddy lake session. Drying rarely comes up. Most swimmers hang the suit on a hook, walk away, and assume the job is done.
But how a wetsuit dries matters just as much as whether it dries. Get it wrong often enough, and you're quietly wearing down the same material that gives the suit its stretch and its shape. That wear shows up later as stiff shoulders, cracked seams, or a suit that just doesn't move the way it used to.
What's Happening Inside the Neoprene
Blue70 wetsuits use Yamamoto neoprene in 38, 39, and 40 cell grades. The cell number describes how fine and dense the foam structure is. Higher cell counts mean finer cells and more flexibility, which is why the thinnest, most mobile panels on a suit like the Helix sit at the top of that range.
Fine cell structures are also more sensitive to how they're treated while wet. The foam itself doesn't hold much water. It's the interior lining and the moisture trapped between fibers that stays damp longest. Left folded in a heap or stuffed into a gear bag, that moisture sits unevenly against the material. Some panels dry within the hour. Others stay wet for a full day.
That unevenness isn't harmless. It's a repeated, low-grade stress on the suit, and it happens every time it gets tossed in the back seat instead of hung out properly.
Why Uneven Drying Is the Real Problem
It's easy to assume the only risk from bad drying is a musty smell. That matters too, but the bigger issue is mechanical. Wet neoprene is more pliable than dry neoprene. A suit draped over a narrow hanger sags under its own weight exactly when the material is easiest to stretch out of shape. Do that fifty times over a season, and you've slowly deformed the shoulder or torso panels, the areas that determine how the suit actually fits and moves.
Chloroprene rubber, the polymer family neoprene belongs to, breaks down faster with repeated exposure to direct heat and ultraviolet light. A car's back window on a sunny afternoon feels like a shortcut to a dry suit. It's also pushing the same aging process along faster than shade and airflow ever would.
Three Habits That Actually Protect the Suit
None of this takes special equipment. It takes paying attention to three things every time the suit comes out of the water.
- Support the shape while it's wet. A wide-shouldered hanger, or even a pool noodle threaded through a standard one, spreads the suit's weight across a broad surface instead of concentrating it at a thin point.
- Let air reach both sides. A suit hung on one bar dries the outer panel first and traps moisture against the lining. Turn it inside out for the first stretch of drying, then flip it back once the interior feels mostly dry.
- Keep it out of direct heat and sun. Shade and airflow beat warmth every time. Indoors, a fan on low pointed at the suit does more good than a heater.
Put those three together and you've built the basic function of a drying cabinet, whether that's a commercial unit or just a corner of the garage with a good hanger and a breeze.
Some Suits Need This More Than Others
Not every wetsuit in the Blue70 lineup carries the same risk. The Helix is built with very thin, highly flexible neoprene through the shoulders and arms, engineered to preserve feel for the water on race day. Blue70 is upfront that this same thinness means the Helix breaks down faster under frequent training use, which is exactly why suits like the Reaction and Fusion use higher-grade, more durable neoprene built for repeated long swims.
That trade-off changes how much drying discipline matters. A Helix balled up wet in a swim bag three times a week is stacking uneven drying stress on top of neoprene that was already built thin for performance. Push that habit through a full season, and shoulder fatigue shows up well before the suit's warranty period is even close to over. A Reaction or Fusion tolerates a bit more carelessness simply because the base material is denser. If you're training regularly in a Helix, proper drying isn't optional. It's part of what keeps race-day performance intact.
Building a Simple Setup at Home
You don't need a dedicated cabinet to apply any of this. A workable setup looks like:
- A wide, rounded hanger reserved just for the wetsuit, kept somewhere with airflow, not sealed in a closet.
- Turning the suit inside out right after rinsing so the lining dries first, then flipping it once the interior feels close to dry.
- Waiting until both sides are fully dry before folding it for storage or a bag.
That last step matters more than it sounds. Folding damp neoprene creases it at the same points every time, and creases in wet cell foam have a way of becoming permanent lines by the end of a season.
If you're swimming often enough to be rotating a wetsuit multiple times a week, setting aside even a small dedicated drying space, a corner with the right hanger and a fan, does the same job as a purpose-built cabinet for a fraction of the cost.
What This Means for the Life of Your Suit
Blue70's one-year warranty covers manufacturing and material defects, not wear and tear. A suit that delaminates at the seams after a season of being dried folded on a bathroom floor isn't a defect. It's a habit that added up swim after swim.
Treating drying as part of a wetsuit's actual performance lifecycle, not an afterthought squeezed in after the real work of rinsing, is one of the simplest ways to keep the neoprene doing its job: staying flexible, holding its shape, and performing the same on your last open water swim of the season as it did on your first.
