Durable and fast drying
These dry almost instantly after a shower. The material feels high quality and doesn't absorb too much water, making turns in the pool much easier.

Solid training suit
Good compression without being restrictive. The drawstring stays tied which is a nice touch. Would be perfect if they offered more color variations.

Perfect for daily lap swimming
I swim five days a week and these trunks have held up incredibly well. The chlorine shield really seems to work as the fabric hasn't faded or stretched out after three months of heavy use.

Recommended for my swim team
Bought a batch for our youth team. They love the comfort and I love the price point. They withstand the harsh pool chemicals better than other brands we have tried.

Best swim trunks I've owned
The Chlorine Shield technology is no joke. My old suits would get baggy after a few weeks, but these still fit like new. Highly recommend for serious swimmers.

Great value for competitive swimmers
Very comfortable and hydrodynamic. The fit is snug which is exactly what I need for racing. Only giving four stars because the sizing runs slightly small, so order one size up.
Q: Is the drawstring adjustable while in the water?
A: Yes, the drawstring is designed to stay secure during vigorous activity, but it can be adjusted if needed. Most users find the initial fit sufficient without needing adjustment mid-swim.
Q: How does the sizing compare to standard US sizes?
A: Our WWK1 model tends to run slightly smaller to ensure a competitive compression fit. We recommend checking our size chart and considering sizing up if you prefer a looser fit.
Q: What is the expected lifespan with daily use?
A: With daily chlorinated pool use, most customers report 6 to 9 months of optimal performance before noticing significant wear, which is above average for this category.
Q: Are these suitable for open water swimming or just pools?
A: While designed primarily for pool training with Chlorine Shield, many customers use them for open water swimming as well. Just rinse thoroughly with fresh water after saltwater use.
Q: Can these be machine dried?
A: No, we strongly advise against tumble drying. High heat can damage the elastane fibers and reduce the lifespan of the Chlorine Shield coating. Please air dry only.
