most comfortable underwear for men

I've put it through the wringer

I have tried so many brands and styles until I found this Patagonia one. Nothing feels as comfortable as they do. I ordered them in every color possible and I am sure I will need to order more as I wear them daily. I work in construction and comfortable clothing is very important for me as I am put there all day doing physical labor. There Patagonia underwear will definitely be part of my work gear now.

second pair still love

I've used it several times

Been using these for a year and needed a second pair. They are great light and hold everything needed in place. They fit true to size and I would buy again. I use them working out and plan on hiking with them and taking them on all future trips.

I've used it several times

Love these boxer-briefs for daily use and out on the trail. Super breathable and wicking. Fit is really comfortable as well; right on the cusp of M and L per the sizing chart and L fits well.
