Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 5 out of 5 by from Best of what I found so far [This review was collected as part of a promotion.] I have a big rib cage, longer body and small breasts. It's insanely tricky to find anything for such combo. This bra is the best I've got so far but still can feel it at the end of the day pressing on my rib cage. The temperature regulation option is nice and it absorbs moisture nicely.

Rated 5 out of 5 by from These fit me the best! I never tire of these merino wool bras. They are supportive and easy to wear. In a perfect world, the elastic band would be covered in soft cotton, but that’s my only caveat.

Rated 5 out of 5 by from All you need This bra is my go to now. It feels and looks great and I can wear it for everything except an activity that needs something w heavy support. For every day and hiking, you can’t beat this one. Size up.

Rated 5 out of 5 by from New favorite bra [This review was collected as part of a promotion.] I love the feel of this bra. Soft and comfortable. Light and supportive, and it doesn't cause the underboob sweat I hate.

Rated 4 out of 5 by from it's an excellent bra...but still a bra [This review was collected as part of a promotion.] I don't really need a bra but bought this for light support and modesty under T-shirts while hiking. It absorbs sweat, doesn't smell, and is pretty comfortable, for a bra. On the down side, there's no back clasp, so it's hard to take on and off. And, it's too thin to actually provide the nipple coverage I was hoping for. And, there's still an elastic band cutting into my ribs...which I guess is unavoidable, as I have never found a bra that doesn't hurt me in that spot. So, if a bra MUST be worn, this is a decent choice. Wish it had a back clasp.

Rated 4 out of 5 by from does the job Great merino underwear. I usually wear S in icebreaker but the S bra seemed rather tight (around the chest and in the cup) so I ordered the M as well. Both were a little floppy at the very top where it meets the strap, but more pronounced on the M. It's not the best cut for my body type but it will do the job while hiking. I'm actually 5'-3.5" tall (in between sizes).

Rated 5 out of 5 by from Comfiest bra! The comfiest bra! Wore for a 3 day backpacking trip, even slept in it with no desire to take it off or change. Dried quickly & zero odor. I do wish it came with bra cups, but took a pair out of an old sports bra & reused in this bralette. Purchased in multiple colors, this is the only bra I ever want to wear anymore. I’m 5’1” 120lbs, small busted 34B cup and a size medium was perfect. Maybe runs a little on the small side, but I knew to take that into account when ordering. Had no issues with the straps & had a 32lb pack on my back!

Rated 5 out of 5 by from Awesome [This review was collected as part of a promotion.] This bra is cute and doesn’t scratch. I ended up sizing up to get a more comfortable fit. I’m 34D/DD and got a large. The medium fit but was a bit tight.
