Best underwear ever

Best underwear I have ever owned

My first. For fifty bucks, hard to not be critical. However a few weeks tells me nothing. Haven’t washed em yet nor really got down to some nitty gritty backpacking. I like the feel and fit. Soft and warm. I don’t know how they’ll handle sweltering days on trail. Other than some weird thread snag fluff around waistband the quality was good. I would except a little more eye on machining detail fir cost. I would recommend the boreal is 72 hour briefs.

Great briefs.

Very soft Merino wool. Perfect length. Worth the price.
