Most triathletes rinse the suit, drape it over a fence or a shower rod, and call it done. That habit is quietly responsible for more premature wetsuit wear than fingernail punctures and heel tears combined. The fix costs nothing and takes about five extra minutes.
Neoprene is a closed-cell foam, sandwiched between a jersey lining on the inside and either more jersey or a smooth-skin laminate on the outside. When you climb out of a lake, a pool, or the ocean, water settles in three places: the outer surface, the absorbent lining fabric, and the folds where the suit presses against itself on a hanger. That third spot is the one nobody thinks about.
The Problem With Folding a Wet Suit Over a Bar
Drape a wetsuit flat over a single bar and it folds sharply at the underarms, behind the knees, and across the chest. Moisture gets trapped against moisture in those creases. The lining underneath stays wet long after the outside looks bone dry.
Two things happen when a suit sits wet longer than it needs to. Chlorine keeps breaking down the polymer chains in the rubber while it's still in solution against the neoprene. Salt crystallizes in the weave of the lining and works like fine sandpaper every time you bend an elbow or a knee. Meanwhile, the glued seams holding the panels together soften slightly under sustained moisture and warmth.
None of this destroys a suit after one swim. It adds up. A suit dried well after every session holds its shape and flex through a full season. One that's routinely stuffed damp into a gear bag between races starts feeling stiff months before it should.
Why Moving Air Beats Still Air
Two habits make the real difference: hang the suit in the shade, and dry it with air that's actually moving.
Shade is the easy part. UV exposure degrades neoprene and fades panels over time, and most swimmers already know to keep gear out of direct sun. Airflow is the part that gets skipped. A wetsuit left in still air dries from the outside in. The exterior feels dry within an hour, but the lining against your skin and the neoprene underneath it are still holding water.
Here's why. Evaporation rate depends on the gap between the vapor pressure at the wet surface and the vapor pressure in the surrounding air. In still air, that gap closes fast, the air right next to the suit gets saturated, and evaporation slows to a crawl. A box fan or oscillating fan pointed at the suit keeps replacing that saturated air with drier air, which keeps the evaporation rate up for hours instead of minutes.
The result: drying time drops roughly in half compared to still air, and the suit dries more evenly across panels, seams, and lining, not just the parts you can see.
What You Actually Need
- A wide, curved hanger built for wetsuits, or a padded shoulder hanger meant for heavy garments
- A shaded spot, indoors or out
- A standard household fan set to low or medium, positioned a few feet away
That's it. No specialty drying rack, no dehumidifier, no gadget.
The Hanger Matters as Much as the Fan
Airflow only helps if it can reach the suit. A standard wire hanger creates a sharp fold at the shoulders and crushes the underarms, which happens to be where sweat, sunscreen, and lake water build up the most. A wide, rounded hanger keeps the shoulders and torso open, giving the fan something to actually work across instead of a folded lump of neoprene.
Turn the suit inside out for the first stretch of drying. That puts the lining, the layer against your skin, in direct airflow instead of leaving it to dry last and slowest. Once the lining feels dry to the touch, flip the suit right-side out and let the fan finish the exterior.
It also helps to vary how you hang the suit over time. Hanging by the waist occasionally, rather than always by the shoulders, reduces the chance of stretching the shoulder panels out of shape. This matters most on thinner, more flexible neoprene, the kind built for full arm rotation in a race-day suit. Blue70 is upfront about this trade-off with the Helix: the thin, flexible neoprene that makes it fast also makes it more sensitive to wear from frequent training use. Good drying habits are one of the few variables a swimmer fully controls to slow that wear down.
A Simple Post-Swim Routine
- Rinse the suit inside and out with fresh water right after swimming, before salt or chlorine dries into the fabric. A hose or shower works fine for routine rinsing.
- Hang the suit inside out on a wide hanger, in the shade, with a fan running for the first hour or two.
- Flip it right-side out once the lining is dry to the touch, and keep the fan going until the whole suit, seams included, is dry all the way through.
Traveling to a race with a still-damp suit? Roll it loosely instead of folding it at sharp angles, and hang it back up the moment you reach your hotel or campsite.
Why This Is Worth the Five Minutes
Blue70's one-year warranty covers manufacturing and material defects, but it doesn't cover wear and tear or damage from heat and chlorine exposure. That's worth sitting with for a second. How you dry and store your suit between swims is entirely on you, and it's also one of the easiest things to get right.
A suit that's cared for properly holds its flexibility and buoyancy characteristics season after season. One that's routinely wadded away damp starts losing that responsiveness long before it's actually worn out.
This isn't about babying your gear. It's about recognizing that five minutes of proper drying does more for your wetsuit's lifespan than almost anything else in your routine, including how carefully you put it on or peel it off in transition. A wide hanger, a shaded spot, and a fan running for an hour or two is a small habit. It pays off over years.
