Questions about fit, comfort, and returns
Clear answers to help you choose size and try risk-free
How do I pick the right size for my build?
Will this feel restrictive during a full workday?
No. The four-way stretch fabric gives gentle compression while allowing movement, so you can sit, bend, and commute comfortably without pinching.
Can I wear this under dress shirts or gym gear?
Yes. The seamless design and slim profile make it invisible under dress shirts and fitted gym tops, reducing bulk and improving silhouette.
How do I use the zipper and snap crotch discreetly?
The anti-chafing zip front closes smoothly under clothing, and the snap crotch lets you use the bathroom quickly without removing the whole garment.
What's the return policy if the fit isn't right?
We offer a 30-day fit guarantee with free exchanges and easy returns. Try it with underwear on and contact customer care if you need a different size.
