I bought these to sleep in and they are soooo comfortable. 5’5” 125 pounds and bought the XS. If you’re buying these to work out, I would consider it medium impact. The strap at the top of the shoulder bunches up too. Not uncomfortable but if you’re wearing a tight shirt it would be noticible.These Sports Bras for great. For the price it’s hard to beat. I don’t put them in the dryer, because I did once and they pilled a bit. Other than that I love them. Would definitely repurchase.These sports bras are AMAZING. I tried them because I love this brands yoga pants. These are the best sports bras I own and I am slowly replacing all of my other, less comfortable bras with these. They offer great support w/o any uncomfortable rolling or digging. However the truly magical thing is the cup insert. Being of small boobs myself I keep those inserts in so I'm not nipping out all the time, but the fact they come out or roll up/fold over in the wash is one of the most horrid things on the planet. These don't do that. I repeat: the cup inserts don't roll, fold, or escape in the wash. I'd seriously pay twice as much for that feature alone. Anyway, 10/10, gold star, could not recommend more highly.Comfortable when I first put it on. Started hurting after a couple of hours. By hour 4 I couldn't wait to wake it off, diggingin my shoulder neck area. I was not exercising, just riding in a car. Size 36 dd or ddd. I need something that is comfortable all day so this is going back.The bra is very comfortable. I would not consider a high impact fit. Especially if you are larger busted. Cute. Comfy. Good price.These are super comfy, true to size, but are more for medium impact, NOT high impact. But they're the best ones I've found and I'll definitely purchase more and recommend to others.For a little more snugly than I usually prefer, but that probably makes them better for running (not that I actually do much of that, lol). The only thing I don’t like about them is that the cute cross-straps never seem to sit right. After about 10 min of wear, the straps bunch up and begin to cut in to my shoulders, causing (eventually) deep red marks.I usually wear a 2x/XXL and I ordered a XXXL as some reviews said they run small. It fits like an XL in my opinion. Bit tight on the back and leaves spillage over the sides. I'm a 40 D for reference. Great quality though and good support. I'm hoping they'll loosen up a bit with wear.
