THE ONE THAT STARTED IT ALL.
Five years. Countless restocks. Still selling out. The Signature Brief /Black is the brief that put ThePack on the map — and it hasn't stopped turning heads since. An original icon. #LiveLouder
THE DESIGN
Flattering low-rise cut made to accentuate every angle. Embossed ThePack branding across the glutes — bold, unmistakable, and the detail everyone fell in love with. From poolside to mirror selfies, this brief is built for impact.
THE FABRIC
95% polyester / 5% elastane — reliable stretch, everyday comfort. Heat transfer care label — zero distractions against the skin.
Customers praised these briefs for their "excellent style, cut, fabric" and great fit. The thin material creates a sleek, attractive look described as "so sexy," though it offers minimal support and can be quite visible. Sizing runs small for some shoppers. "Great fit, fabric is really nice" and comfortable for everyday wear.
Great-looking, smexy pair of undies from The Pack! Keep in mind that they feel a bit loose when actually swimming laps or doing hard strokes though they’re totally fine for casually treading water. Overall, I love the look and fit for wearing under swim trunks. I’ll definitely be picking up their dedicated swim undies on my next purchase!
Thanks so much, Eric! Really glad you’re loving the look and fit . Appreciate the helpful note on swimming too! the Signature Brief is made more for everyday wear, so our dedicated swim styles will definitely be the better pick for your next pool day! Sending love 🖤🖤🖤
so sexy
Excellent style, cut, fabric
Good
Love all my Pack Underwear!!! Great fit, fabric is really nice!!
The pack fits me well. Clearly this is made for muscular guys!
THEPACK BLACK BRIEF: The brief was perfectly shipped and it arrived in a week. It is made with a very thin material so it doesn’t support your pack so you have to know it gets quite visible. I am 165cm tall and a bit musclular: I chose the S size and I have to say it is already a bit small to me
I bought these on a whim as I don't usually wear this style of underwear and was pleasantly surprised. I have a 37" waist with 25" thighs and the XL fit great - not too tight and not too loose. When I took them out of the package which came in a really cool black can (like a coke can), I wasn't sure as it looked a bit too low waist for my liking. However, after wearing them for the first time, this was not an issue at all. They were very comfortable and looked great in pics. Now Im hooked on these prints.... :p
personalized service and awesome products .. ethan is on top of it! cheers bro!
