Doesn't work for larger boobs

I was really excited to try this top as I'm always on the look out for sports bras that don't compress my lats and a few people had recommended me the luna bra. However, it's just not workable for me with 34DD bra size. I also tried sizing up but there really just isn't any space for your breast and the fabric doesn't have much give. Unfortunately sizing up again wouldn't work as then it's started to sag around the waist. I've actually never had this issue with a sports bra before as I usually prefer a low impact bra which is what I thought this would be from the description. Would love to see this released in a version for people with mid-large *******. As the general cut and shape is very flattering and I can imagine how it would be comfortable if it fit right

Comfortable and covering

Nice longish bra, dries quite quickly, so was pretty good for deep water soloing.

Super comfy bra

Along with the Saturn, this is the most comfortable bra I have ever owned. I'm really glad 3rd rock gives so much thought into how well their clothes fit. Customer service ist great as well. I am glad i read so many reviews of the Luna before because I went for size M instead of S and that was a good Idea. Defo recommend sizing up. I like the fabric but usually prefer the cottony fabric of the Saturn bra so I wish they had both options for the Luna. This won't be my last Luna for sure.

Luna bra

Really comfortable to wear and really supportive. Stays put and doesn’t ride during overhead reaching and long enough to wear as a top on sweaty crag days!
