I don’t have huge boobs, but they definitely bounce when I run/walk fast - I love my TALA sports bras, thry’re supportive like my best friend and I want to get home Oner Active ones too. I’m not sure how supportive Oner are, but TALA definitely makes me feel supported (I’m a 34D) also like that the washing instructions are sewn into the bra so no annoying labels that itch. The fabric (to me) is soft, but thick and I think that helps with the support. It comes with cups but I remove those. It is a little stiff to get off, but the support (for me) is worth it. Also has been washed soooo many times and is about a year old now. Hope this helps, lovely! Also, what did you mean by front or back close? 🫂 https://i.nostr.build/4I5yRHUOJyBYCEhJ.jpg https://i.nostr.build/RmrF3392zM7AVcWX.jpg
