Hear me out. Deluth Trading CO's Buck Naked line. Honestly, after I tried a pair I replaced all my boxers with them. They're so comfortable and they last a really long time. 10/10 would recommend.

They are both already mentioned but I love deluth undies and woxers. They are light weight and breathable and go on sale often. Definitely worth looking into!

I’ve seen Woxer mentioned as an alternative to TomboyX, but they look kind of pricey too.

Bloke here.

Check out Under Armour Boxers. They are by far the best I've had. Next to no seam on the inner thigh, comfortable, stretchable they are awesome. They are slightly more pricey. 2 pairs for around £20 on Amazon but worth every penny. After I tried them I spent £200 and threw every other pair of boxers in the bin. That was 3 years ago and I have never wore a pair out yet.

I will say I have Skin Grafts on my legs and used to get a lot of chafing on sensitive skin but not with these.

Worth every penny.

I like the men's gap breathe boxers
