Are Swim Shorts Waterproof? Here’s What You Actually Need to Know

Are swim shorts waterproof? Here's what that really means

When we say ‘waterproof,’ we usually think of raincoats or wellington boots (gear that keeps water out completely). Swimwear works differently. It’s not about repelling water; it’s about being water-compatible.

Take Sheila swimwear, for example:

• Lightweight when wet so it never weighs you down.
• Breathable and supportive for comfort in and out of the water.

Think of it this way: swimwear is designed to work with water, not against it, so it won’t stick to you like Glad Wrap. Our recycled nylon with elastane lets water flow through, then dries easily so you stay comfortable.

What sets Sheila swim shorts apart from other non-waterproof swimwear

The proof is in the details.

Certified safe, inside and out

Our swimwear holds the STANDARD 100 by OEKO-TEX® certification, meaning every component (from the resilient elastane to the smallest accessory) has been tested against a list of up to 350 harmful substances. This ensures our swimwear is safe for our workers, our wearers, and the world.

Full range of motion

Whether you’re diving into the ocean, chasing kids through the shallows, or floating on your back, these shorts move with you. The cut and fabric work in sync to give you complete freedom without bunching, riding up, or weighing you down with water.

Addresses your real concerns

See-through when wet? Not with our full lining. Clingy and uncomfortable? Our fabric stays light and airy, even when saturated. Slow to dry? They dry faster than you’d expect, so you can get on with your day.

The bottom line

While swim shorts aren't technically waterproof, the right ones (like ours) are purpose-built for water life. They're the perfect middle ground between traditional bikini bottoms and those stiff board shorts that never quite fit right.

From morning swims to afternoon adventures, they're designed to keep up with real life, not slow it down.
