Care for your layer

Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F). Use a mild wool-safe or pH-neutral detergent. Wash with similar colors. Don't bleach or use fabric softener.

Reshape while damp and lay flat to dry. Don't tumble dry, twist, or wring. Cool iron if needed. Store folded in a cool, dry space with airflow; avoid hanging.

Naturally dyed colors can transfer with sweat or friction. Wear them with dark clothing or equipment, wash sparingly, and avoid citric acid, which can lighten the color.

Good product

I was hoping to be able to use this for a fast pack but the support is just not there for running. It is a nice hiking bra. I had to wash it before I wore it because it was a quite a bit itchy. But it fits well and looks like it's going to last.

Very happy with this bra

It’s really comfortable! I needed something that would hold my insulin pump when I wear a dress and don’t have a waistband to clip the pump on. This works very well!

Hi Lisa, thank you so much for sharing your experience! We’re really happy to hear it’s working well for you and helping make things easier. We truly appreciate you taking the time to leave your feedback

Sport bra

I really wanted to like my new bra as I am trying to transition to natural clothing. But unfortunately my experience is the same as some other reviewers. I wouldn't call it a sport bra as it doesn't offer much support. It fit me well just trying it on but just wearing it for first time on my 30 minute run it stretched considerably. It retained its shape and size after washing it but after wearing it again the bra ended up being oversized again.

I want to love it ..

but it's now quite what I was hoping for. The material is excellent and soft and moisture wicking. The fit, however, is less desirable. I got an extra large and there is no room for extra large breasts. The racerback is too long making the bra somewhat ill-fitting. The biggest problem though is that anyone with anything over a b cup will be popping out the sides. Also, it couldn't be called a sport bra because there's really no support. Basically it just keeps you from swinging around too much.

Hi there, thank you for sharing your honest feedback. We're glad the material worked well for you, and we appreciate your notes on the fit and support. This helps us as we continue improving our designs!
