Common Questions about Swimskins
Swimskins vs Wetsuits
Wetsuits are thicker and bulkier that swimskins and generally are used more for warmth and buoyancy. Swimskins provide neither of those, instead focusing more on the aerodynamics and hydrophobics to make the swimmer more streamline through the water.

The advantage of a wetsuit is for colder races since they do provide warmth, but for some races with water temps in the high 70’s and above, wetsuits could be illegal and dangerous due to overheating. That is really where the skimskin has it’s advantage since there is little risk of overheating due to the thin fabric.

Are Swimskins legal in Triathlons?
Yes, always. Swimskins are not considered wetsuits so they are legal for all triathlon swims, even if the water is too warm for wetsuits.
Do Swimskins improve swim time?
Yes, typically swimskins improve swim time by making you more aerodynamic and reducing drag. Having a singular piece of material with specific fabric that is hydrophobic, which repels water, helps the swimmer move through the water faster.
How to you wear swimskins?
Swimskins are meant to be worn over your tri-suit and are taken off after your swim in transition.
