Solid and comfy
Size: Medium, Color: Black (001)/Jet Gray
Absolutely love these sports bras. They’re simple and solid, and I love the colors! They do run small, so I’m glad I sized up. I’m usually a small, but got a medium and they fit perfectly. For reference I’m 5’5”, 125lbs, 34B. They wash well too! Just make sure to air dry them and wash on cold only.

Great bra, poor customer service
Size: Medium, Color: Black (001)/Jet Gray
I like this bra. It offers great support. But the sizes run small. I remembered this after placing my order. So I got back with Amazon two times within six hours of placing the order to cancel, so I could exchange it for a larger size. Amazon would not cancel the order. And they have no option for exchanging it. They used to allow 24 hours before processing an order. Not so here.

best bra for big chested girls!!!
Size: Medium, Color: White (100)/Halo Gray
The best sports bra!!! I’m a D normally if we are talking Victoria secret they would probably say I’m wayyy farther down the alphabet. Basically I’m pretty big chested and this bra is everything I could ever want. Not only does it actually hold up the girls but I can jump and they will hardly move. The biggest problem I have with sports bras is there’s zero support and my boobs kinda just sag but this actually make me feel like I’m three cup sizes smaller! I did size down to a medium but it still fits me perfectly. I’m going to order this is every color just because ITS THAT GOOD!

Runs small; size up!
Size: Large, Color: (648) Prime Pink / / White
Nice! Size up! I ordered a large and it fits great! I'm 8-10, medium in everything else so I thank previous comments saying it runs small. It was quite comfortable, but if it is moisture wicking, I sure couldn't tell!

SIZE UP
Size: X-Large, Color: Black (001)/Jet Gray
Great material! However, has little to NO stretch so would highly recommend sizing up two sizes. I sized up one size and it BARLEY fits lol
