Stay put leg seam
the leg seam is a little tight when you first put them on, but loosens up and they stay put.

Like the longer leg on this version
I do prefer the Aspire fabric to the others, and the length helps when wearing jeans that are not too tight in the thigh from your leg getting any abrasion from the material.

Freedom
Finally freedom you desire. Super thin and breathable. No more rash.
Aspire boxer brief in large fit true to size. Aspire zero brief felt just a bit small. Tight pressure on my abdomen is uncomfortable. I’m 6’2” weigh 195.

Hi Ryan,

Thank you for the 5 stars. Great to hear the Aspire Boxer Brief gives you the freedom you wanted. The thin, breathable design solves the rash problem, which is exactly what we aim for. Your sizing feedback is helpful—sounds like the large boxer brief fits just right, while the zero brief runs snug. At 6'2" and 195, the boxer brief seems like your best fit.
