Rated 5 out of 5 by from HATE getting freezing cold post-run because of your bra? Well, I do, too. I *finally* figured out that I get really, really cold after running because of my old sports bra. You know, it's been raining or I've been sweating good and hard, and my bra is soaking wet. Even if I put on a clean, dry shirt, I'm still really cold because of that clammy, icky material clinging to my chest. Enter the PhD Seamless Racerback Bra. It's the perfect solution. It's one piece (no hooks, adjustable straps, etc.) and no matter how wet it is, I don't have to do the sports bra-extraction-shimmy in my car, because even though it's wet, I'm NOT COLD. Merino wool is just that awesome. Yes, they are a wee bit pricey, but they are *totally* worth it. A++ totally recommend!!!

Rated 4 out of 5 by from Testing for Backpacking is on... I will be backpacking for 7 consecutive days this summer. I have heard that smart wool products are the way to go to minimize smells and for easy hand washing and quick drying. So, I am conducting my own experiments. So, far the smell factor test and drying fast tests have gone well, for the underwear and bras. I have been washing with bar soap, because that is what I will have on the trail and these tests have been positive. I purchased the same size as I normally do and the bra is a bit bigger than I would like . I have never worn a wool sports bra before so don't know if this Product runs bigger? I do plan on buying another smart wool bra at the next smaller size.

Rated 4 out of 5 by from I'll be buying another I'm pretty picky about sports bras. I really like this one because it has the wool material on the inside which doesn't seem to get as stinky or gross feeling and then elastic on the outside like a normal spots bra. It's comfortable and keeps everything in place. I normally have the issue of sports bras riding up so I was worried about getting the small which is my usual size, but it fits good and and I have very little of that issue (not sure if I'll ever find w bra that I don't have that completely didn't do that). Another breath thing is I washed it and accidentally dryed it, but it was fine, unlike most wool products that are ruined when you do that.

Rated 5 out of 5 by from Stink-Free, Dry, and So Comfy I Forget It's On This truly is the best sports bra ever made. It is more than supportive enough for what I need - I'm a 34B or 32C, cyclist and yogi (not a runner so don't know about that), size small was perfect. It seems to just become part of my body and I forget it's on, while the girls stay firmly in place. And it really does not smell. Wore it 8 days in a row to test it out, including exercise and at work, and I am a really sweaty person. It did not smell. I believe I really did sweat less with this bra. Also I could wear it after a workout and never uncomfortably wet or cold. I will be stocking up.

Rated 5 out of 5 by from I love this bra I bought one of the PhD Seamless Racerback Bras to wear when I climbed Denali's West Buttress this spring, and then after training in it for a bit, I came back and bought another one. I have a size C bust and this bra is my new favorite all around - great support, comfortable both to move and sweat in, doesn't get smelly (climbing Denali is a 20+ day endeavor - it was dirty, but it didn't get smelly!), and, let's face it, we all care - it looked nice on, too - it flattered my figure, as opposed to an Ibex bra I bought which, while stretchy, let things just kinda hang too loose. I think this is a terrific sportsbra, and like the colors, too.

Rated 4 out of 5 by from Meh Testing this out for a 200mile hike. Dries fairly quickly, not smelly and the material is fantastic. BUT the fit is a little off. For reference I am pretty small, not broad in any sense. I wear size small in Nike sports bras. 5'6" 120lb 32B and a small is almost too small. I think the shoulders are too short, because the material is too close to my armpits and the band rides up because that's where the shoulder straps take them. I would not get a medium because of the excess material near the armpit. Definitely needs a to be more narrow near the armpits and longer straps for me to buy this again

Rated 2 out of 5 by from Not as described It's not seamless. There are clear seams at the shoulders/on the straps, so I don't know why they would describe the product as seamless! Super frustrating. Also the little air/breathing holes on the bra show through a fitted top, which just looks weird. Most annoyingly is that it definitely is not supportive enough for any medium to high impact activity like jogging. I am usually a 34A. I bought size XS and the material of the bra is very comfortable and stretchy, but so much so in that it doesn't provide enough support and sags in some places. There's bounce and jiggling when I jog. I am not sure what to do now because the store I bought it from online only accepts returns on unused gear. It doesn't smell after use, which is a good thing. But for the very high price I would really expect something more from Smartwool - a bra which is actually seamless and supportive. My first (and maybe last) Smartwool product.

Rated 5 out of 5 by from Love this product! I bought this bra for my upcoming Appalachian Trail hike. It is extremely comfortable and supportive. As someone with a large cup size, this was very important to me. The wool fabric is antimicrobial so it should help with odor on my thru hike. It's also surprisingly soft and does not cut into my skin like other lower quality bras. I'm very excited about using this product on the trail!
