So comfortable for everyday.

I loved this so much I bought four more! It is so totally comfortable and doesn't completely flatten you out. I am a C-D cup and this fits tightly and just fine. No bouncing! I pretty much wear them everyday unless I am getting dressed up or I need a shapelier bust line for something tight-fitting. I wish they came in other colors. They have been washed about 10 times and look great.
If I were a B cup, it would be fine for running too. For me, it is great for walking, hiking, yoga, chores, exercise machines like elliptical, weight-lifting, gardening, etc, etc!

Good Enough

I do like this sports bra, and it does what it's supposed to do. However, I was a little disappointed to find that the fabric is much thinner than that of the sports bra I bought about two years ago from EMS. I'm almost certain that they're the same bra.

In any case, it does the job and it's super comfortable! I would buy it again, but I do wish it felt a little sturdier.

Favorite Running Bra for years

I've been buying this seamless bra for several years and it is perfect support for a 34C runner. It is very comfortable and durable - I wash and line dry, and the lycra has not lost its elasticity even after 3 years of regular use. I stock up whenever there's a sale!

Amazingly comfortable and supportive!

These bras are great! I had two and ended up purchasing four more in all the colors. I love them! They are great for running or for just wearing under a low cut tank top to color coordinate.

Love it

Really comfortable and fits well. The sizes run a little small, as in I always wear smalls but needed a medium here, but once I found the right size I bought three more.

Very Comfortable

I don't like bras but I need one for sports. This is a very comfortable bra, easy on the back, easy to get on and off. My favorite sports bra.

Best Low Impact Bra for Bigger Cup

After dozens of washes and dries - still fits perfect and soft. Fits larger busts - D+ (hard to find in low impact spots bras) -

Negative Reviews:

Comes apart

I bought this bra a few weeks ago for backpacking trips. I wore it for two days in the woods and washed it in cold water, hang dry- the sizing information on the back totally wore off after this. One more washing later and little broken elastic threads are starting to appear at the shoulders. I've owned similar bras from EMS before (much older versions) and never had this problem. Also, the sizing is weird. I'm a 34D and tried on the M/L in the store, which fit fairly well, so I ordered one online without reading the description. Only when writing this review do I learn this is for an A/B cup. Seems like the sizing would be off for someone smaller than a B cup based on my experience.

the old one was better

The old version got wet and stayed wet, but that was its only flaw. The new one dries out quicker, but I guess that's what made it flimsier.
I always liked how the old one had a band that was only just enough tighter than the cup, but now band and cup are almost the same - both too loose - and it (S-M on a 36B) rides up.
I tried one size down (XS-S), but it.. lacked coverage, I guess, and still rode up.

Choose a larger size than you think

I ordered a medium/large after looking at the size chart. Unfortunately I really needed a large/extra large. I am a size 34B so this was a surprise.

Simple workout bra

These aren't the same as the old racer back bras that I bought from EMS a couple of years ago. It's thinner fabric and I had to return M/L and exchange it for an XL and not because I gained weight. Also, there is a crease in between the breasts which used to be on the inside of the bra but now it's on the outside so if you wear a white shirt, your front looks a little funny.
On the other hand, if you get these bras on sale, it's a good deal. It's fine for jogging, working out at the gym, and overall a good fit.

Buy a size larger!

Ran out of time in the store to try this on. It is going back.. I am fairly small and bought a M/L as it looked fine. When I got home and tried it on..it was too uncomfortable for me. Looked like I had flab everywhere - ugh. Should have read the reviews or tried it on.
WhiteMtnRunner at Eastern Mountain Sports (EMS) on 01/01/2013

Tight fit

This product comes in combo sizes, and I ordered the S/M. This item feels like a small, but definitely would not fit anyone who is exactly medium or higher. I tend to run between small and medium, so thought this would be perfect, but it is too small.

Too tight!

I ordered a large/extra large because I need a large band but this bra has a very tight band so I returned it

Wish it were sized larger

Wanted it for horseback riding. Loved the feel but it was just too small. Get the next larger size.

too small

had a small medium which was too small, ordered med/large which seemed as small or smaller.
