Fits like a glove

When I first slipped it on my first thought was “oh oh too tight”. As I wore it I realize that just like a glove has to be snug on your fingers to separate them so the does the underwear. Want to separate your parts? It’s gotta be snug.

No more Swampy Package

Wow! I have to say I am very impressed by these's underwear. The underwear is breathable, lightweight, and can feel like you have nothing on at times. The wind can flow right through them given you have breathable pants or shorts. That airflow feels fantastic. As someone who's a heavy sweater, and I mean heavy where it can look like I took a dip in a pool. I didn't have to walk around feeling like sweat is dripping from my legs or down my bum crack. After having sweated enough to soak the underwear inside where there was little air circulation. I went outside and within 10 minutes I went from feeling the soaked underwear to not feeling them again. If you are used to a specific type of underwear you'll be able to feel the good changes in these. The sack for the boys is nice, but the part that separates the shaft is not enough room for those with a decent size shaft flaccid. Overall, I would recommend these if you sweat and don't like to sit in that sweat or can not change your underwear during the day.
