Comfortable

Great low support option. Fits like a half-tank so good option to go under. Large bust i would only recommend for daily wear not for activity. The comfortable elasticity wouldn't provide the needed support.

Comfortable Sports Bra

These are some of my favorite sports bras. Doesn't have a lot of padding and fits comfortably.

The best

Under Armour sports bras are the only ones I wear! This one is incredibly comfortable with the perfect amount of support. I don’t keep the foam cups in and I still have great support. I wear these to work as well as the gym!

This bra is my new favorite

Originally posted on Under Armour

Yes, I recommend this

This bra fits really well. It keeps itself in place without feeling constricting. It's comfortable and flexible. It's long enough that I can reach and stretch without it riding up and me having to constantly readjust.

Would Buy Again

I like this Bra. It's cute and adjustable! An adjustable strap is so good. It's not quite sturdy enough for me to plan to go running in it, but it would do in a pinch. It's comfortable and versatile. Of the three different styles I bought, this one is for sure my favorite.

Very secure & supportive, perfect for yoga

Yes, I recommend this

In the light indigo colour the padding is really visible, so I found it best to remove it. It covers most of the breast and feels very secure. There's lots of fabric below the bust which stops it riding up. Perfect for yoga and is my favourite sports bra for comfort and support.

I am very busty and it can be a struggle to find bras - this one fit great!! The support is low to medium but I found it very comfortable and is exactly what I wanted.

Not for me

No, I don't recommend this

As a tall slim person, I found that the straps were just a bit too short and dug into my shoulders. Also, it was a struggle to get it over my head because it was too tight and the next size up was too big in the breast area.
