Best boxer briefs with pouch
2undr are the most comfortable underwear I've ever worn.

SAXX Boxers Briefs | Good or Bad option?
Give 2undr a try. I find they are more comfortable than saxx or bn3th.

SAXX Boxers Briefs | Good or Bad option?
This is a huge YMMV item. I find the gussets irritate my skin. 2UNR are similar but the pouch is angled differently and they are the most comfortable underwear I've ever owned.

SAXX Boxers Briefs | Good or Bad option?
I agree with you on the pouch. I generally like pouches, but the Saxx mesh material is itchy and uncomfortable. Bn3th and 2UNDR (and a few others) do it a lot better by using modal around the jewels.

Little luxuries or upgrades that you made this year that makes your everyday better?
I'm a guy, right now I am wearing 2undr swing shift 6 inch boxer briefs. One of my favorite were the pair of thieves performance boxer briefs, but I can't find them anymore as I'm in Canada and they stopped shipping to Canada a few years ago. I've also tried a bunch of others like manmade and saxx but the manmade were weirdly too supportive and saxx gave me chafing if I did anything remotely active.

Best Boxer Briefs For Men
Interesting. I've had 2undr for 5+ years with no issues. Modal is a very nice, premium fabric, though. So that's good. :-)
