I have never left an Amazon review before but I felt too strongly to let this one go - DO NOT BUY FROM THIS SELLER OR THIS ITEM. This top came with three suspicious dark red stains (Blood? Period stain? V8? Possibly other bodily fluids?) which I will post. This is disgrace and this kind of quality is unacceptable and this seller should have their account and frankly, entire business, cancelled all together. I only noticed this after I cut the tags off and tried it on (the fit is not so bad, the fabric seems to be of decent quality, but that was very much overshadowed by the stains). so I don't expect a refund but users be warned - they sell disgusting items, probably the dregs that can't be sold from a retail shop. DO NOT BUY.There's an internal bra that's awkward because it fits funny and feels tight around where it clasps around my chest, but the rest of the tank fits loose. I was hoping to use this for a triathlon and the fitting is just awkward, which is unfortunate because I'm digging the colors and the stash pockets in the back. I might be able to just cut the internal bra out and wear it as a tank with a sports bra.I'm so happy I got this top--I wear it all the time. The three pockets are small, but large enough to hold my cell phone and some snacks during long rides. Lightweight fabric that breathes really well, and a good fit. Yes, there's an awkward "built-in bra" that doesn't do jack, but I wear cami tops on a regular basis with bras, and this is no different. The top is long enough that I don't feel awkward when riding low on my tri bike. I'm 5'9" and 160 and purchased the Large. It fits well.I like this jersey top so much I'm going to buy another one in a different color. Note: if you're, ah, gifted in the upper body region, the built in bra is not very supportive. I was a little worried about that, but the bounce factor is not a big deal on the bike (I'm road biking, not mountain biking) and its super comfortable so I don't mind. If I were doing something else I'd layer a stronger sports bra underneath.The sale price for which I purchased this top makes me like it a lot. It is comfortable. On a bike you may get more cleavage than you would like when in aero but that is a personal choice.I bought for extra layering. I have put it aside for a time being. Love the colors. Placed aside for now.the description did not clearly mention that there was a built-in bra... and the built in bra is not that supportive. so I end up wearing a sports bra underneath it and just not fasten the bra part.I bought this thinking I had finally found the combo of a nice and cool workout style tank top with the convenience of a bike shirt. I guess I would've needed to order one about 5 sizes larger than what I need for it to fit though. This was beyond tight and was very short. The built in bra did seem nice though.
