Comfy bra

Originally posted on Under Armour

Yes, I recommend this

Comfortable for hiking, short runs (up to 4 miles) and weight lifting. When rucking with weighted backback and slender straps with metal rings dig in. That's not good. Otherwise fits well. Easy to get on and off.

My new favorite sports bra!

Originally posted on Under Armour

Yes, I recommend this

This bra is so incredibly comfortable, I enjoy wearing it even when not working out. It eliminates the "solo boob" look. I like the pads, which are removeable. It provides plenty of support for weight lifting, biking, hiking, and even light jogging. Love them so much, I ordered two more!

Great Fit and comfortable for Hot Yoga

Originally posted on Under Armour

Yes, I recommend this

This is a great fit and good for low impact activities like golf or yoga. Moves with the torso. Only issue is the pads within the cups shift after wash and are hard to align evenly. Not recommended for running or crossfit workouts as the support is insufficient. Perfect for hot yoga or regular yoga. Normal bra size 38D and XL fits perfectly.

So Comfy!

Originally posted on Under Armour

Yes, I recommend this

This is one of the most comfortable bras i've ever worn! It's not very supportive, so low impact only...but it sure is comfy and I definitely want more! I followed the size chart and I would say it runs a little large (i.e. I'm a 36DD and I have to tighten it as far as it goes). In the future I would order a size down.

comfortable bra for everyday wear

Originally posted on Under Armour

Yes, I recommend this

I have bought two of this style of bra for my young adult/teenage daughter and she like them both. The medium size fits her well and says they are very comfortable. Mom likes them as they cover her and she is not hanging out all over.
