There have been a few important innovations in men's underwear the last few decades: The elastic waistband. The boxer brief. The removal of that annoying tag from the back. And now, I give you the sack sack.

Actually the latest design innovation from (appropriately named) Saxx Apparel is officially called The Comfort Side Panels. They're a pair of ultra-thin mesh panels that run on either side of your boys, creating a breathable, hammock-like pouch that keeps your package from rubbing against your legs all day. Which lets you stay cool and dry, while providing support and improving comfort. A welcome relief to active guys who are susceptible to the dreaded crotch rot. (Yeah, that's a medical term.)

Saxx come in several styles: Trunk, Boxer Brief, Long Leg and Long Johns. (Notice there are no bikini briefs... lets keep it that way.) And they're offered in three different fabrics, depending on your sack comfort needs. There's Everyday, made of 95% cotton and 5% Spandex for daily comfort; Performance, with moisture wicking fabric for extra dry-balledness; and Bamboo.

I know what you're thinking: "Isn't bamboo sharp, pointy, and made into bad Kung-Fu movie weapons? I don't want that anywhere near my manliness." But if you've ever worn anything made with this incredible fabric, you know it's super soft and lightweight, and Saxx adds a moisture wicking and anti-microbial finish for extra ball care. I'm wearing a pair of Bamboo boxer briefs right now as I type this. And Little BG has never been happier.

As an added bonus, for the entire month of November, Saxx will donate $1 from every pair sold to the Movember Foundation, to help with the fight against prostate cancer. So not only are they providing comfort for our junk, they're helping protect them too.

To grab a pair, head over to SaxxApparel.com. They start at $23.99, which is a small price to pay for keeping the boys happy.
