✨onewith✨ vs. traditional swimwear

other swim
edgeless (no digging!)
no squeezing (elastic-free!)
no hidden seams inside
raw-cut (lays-flat on the body!)
inner grip inside to keep secure
made with 2 layers of fabric

normal swimwear squeezes & digs 😢 but onewith is dig free + elastic-free! 🤩

🚫 there are no tight seams or elastic in any of our suits, so when you're wearing your best size, our swim won't dig in.

important info for when you get your onewith ‼️

this is swimwear unlike anything else on the market, so with that, it has some special instructions to truly get a fit that's onewith your body ✨ 'warming up your onewith’ (aka giving the garment a stretch) is MISSION-CRITICAL to the fits-like-undies vibe. your swim actually SHOULD dig in a bit to start if it’s your proper size. then, with a stretch at the openings, it should fit and feel smooth, like a second skin (and/or your fave seamless undies) 🫧
