I really adore these! The material is soft but good quality and not thin. They’re perfectly cut to flatter any body, and the stretchy waistband is thick but not to the point where it digs in your skin. I normally wear a size L and I sized up to an XL and I’m so happy with the fit. The brief style is so adorable and I give these a 10/10 for being the most comfortable underwear I own

Waited to review...

Size: Small, Color: Dark Colors

SO so hard to buy underwear online. I liked Hanes cotton boxer briefs. but they changed the fabric a few years ago. While I preferred the cotton feel of the old ones, I eventually had to move along and try something else. These wash very nicely--and I dry mine in the dryer with no shrinkage. They don't ride up which is awesome. I have had mine for months so I can fully recommend them now.
