Brighton Briefs

Measure your waist by wrapping a measuring tape around your “natural waist”, which is traditionally near the belly button and the smallest part of the waist.

Measure your hip by wrapping a measuring tape around the hip at the largest part of the hip, taking care to keep the tape even all the way around the hip.

These are the best undergarments ever for running. They fit well, don’t move during the run, and absorb all the sweat, without causing friction or feeling all wet - or turning smelly, for that matter. They are visible, though, but not terribly.

Ah man, these are such a great idea. I loved these a lot, but there's a reason that most underwear without durability issues have cotton linings. These quickly developed holes in a crucial location, and far faster than they should given the price. Glad for the warranty replacement, seriously, but please make these with a gusset to make them last a bit longer.

I LOVE these underwear. I’ve tried most of the wool blend underwear out there and these are the best, hands down.

For endurance, maybe, but not in hot weather

These briefs might be for endurance runs, but not in hot weather. They were dripping at the end of a 2 hour easy run in Miami, FL. They are quite thick and the moisture wicking features didn’t withstand the high temperatures. They felt hot, too. I really wanted to like them and take them with me on multi-stage dessert races, but they are a no-no.

I tried these out on a 4 mile easy run this morning. It was super humid and warm morning in Texas. I completely forgot I had these on. They were super comfortable and not totally drenched in sweat like my sports bra and top. I am going to get a few more pairs soon (my birthday is coming up). I am a size 8 so I order them in a large and they fit perfectly.

Awful sizing, not dry

The leg hole seams are incredibly tight and super itchy and irritating while the rest is quite large, fits loose and sits up near my belly button, a very high brief not a mid or bikini for sure. They didn’t sit well under my leggings at all, and I have to wear a high rise legging to go to the top of the underwear. I purchased my typical size so I’m disappointed they were too big and too small at ... Read more

Under Cover

In developing underwear for running we selected a high-stretch and incredibly soft fine gauge Merino wool that's engineered seamlessly. The performance properties of Merino makes them perfect for running, while the seamless construction reduces chafe and disappears under tight-fitting apparel.

EDITOR'S NOTES

"I’ve run as long as 34 miles in them and can pay them the ultimate compliment: I forgot I had them on."

Cut for Comfort

These mid-rise, full coverage briefs feature a seamlessly knit rib waistband and front panel for added support. Open stitching throughout the leg and back enhance breathability and deliver a barely-there feel. The minimalist design ensures these briefs stay in place and will not ride up when you're moving fast.

Merino Magic

If you're still not familiar with the performance benefits of Merino wool, be prepared for a revelation. Stunningly soft and not at all scratchy, Merino wicks moisture and regulates temperature just like animal hair (because it sort of is). It's almost completely impervious to odor. And it's sustainable, too. For our underwear, we used a super-fine micron Merino with 83% wool, 12% nylon and 5% elastane.

On the Go

For runners with big goals or those inspired to explore, traveling to races can unlock speed and heighten our connection to our sport. Inspired by runners on the go, we designed a collection of travel-ready staples crafted for comfort and sophistication in transit.
