Stealthskyn™ is defined as a performance base layer, but our customers and myself alike, wear them to replace underwear all together. The cooling effect of Stealthskyn's 3D Molded Aerator Pouch as you move, is beneficial to our health whether you are performing aggressively or passively. I wear my Stealthskyn's 24/7.

I’m wearing a small Trunk style here. Notice that the Trunk style below is low rise. The waist is cut approx. 2cm lower, and the leg openings are cut 3cm higher than the Boxer Brief style. Those who like a bit more coverage all around should try the Boxer Brief as their first Stealthskyn experience. *Please note that the leg openings are intentionally designed slightly snug so that the Stealthskyn can adapt to your unique physiology. If you would like to expedite the body-heat activated molding process, please use your finger tips to give them a gentle stretch.

Height: 5’9 (175cm) weight: 175lbs (79kg), waist: 30in (77cm) legs: 23-24in (60cm) upper quads.

Both Small and Medium fit me well due to the body heat contouring technology of Stealthskyn™. I prefer to wear the small Boxer Briefs & Trunks during athletics, and medium Trunks during the day. Trials with athletes and performing men of varied disciplines and careers has taught us that for your first experience with Stealthskyn, you should stay true to size.
