Why Your Curves Will Love It:
-
Friction-Free Outside Underwire: We flipped the script! The underwire is innovatively placed on the outside of the cups. This genius design makes it the ultimate underwire sports bra, preventing the wire from directly contacting your skin and completely eliminating digging or irritation while delivering heavy-duty lift and separation.
-
Modesty on Your Terms (Bonus Included): Love the cooling feel of an unlined bra but worry about show-through? We've got you covered. Every ComfyArc bra comes with complimentary nipple covers and modesty pads, giving you the flexibility and confidence to wear it exactly how you want.
