🧺 machine washable · 🐰 relaxed oversized fit, S–XL · 📦 30-day returns

bought it as a joke for my roommate and she has not taken it off in a week. it's actually thick and cloud-soft — not the sad costume kind — and her face in the little mouth sends me every single time.

maddie k.

designed for a relaxed, oversized fit — baggy, slouchy, and a little ridiculous on purpose. the plush character head is deliberately huge (it's the whole point).

S — 5'0"–5'3", up to 130 lbs (cozy)
M — 5'3"–5'7", 130–170 lbs (relaxed + roomy)
L — 5'7"–5'11", 170–220 lbs (comfy + roomy)
XL — 5'11"–6'3", 220–270 lbs (max room)

between sizes? SIZE UP — the baggier, the cozier. heads up: fits are based on the product class; exact measurements are being confirmed with our supplier.

thick plush fleece with a dense, cloud-soft matte pile — the blanket kind, not the thin shiny costume kind. care: machine wash cold on a gentle cycle, then air dry. no bleach, no iron, no high-heat dryer (heat is the enemy of fluff). be nice to it and the fluff stays fluffy.

see it in motion

the photos undersell it. thick plush fleece with real weight to it, a head that's way too big for the body, and the mouth reveal that gets screenshotted into every group chat. ugly-cute is a lifestyle.

last doubts? we got you

no — and this is the hill we die on. every onzis is thick plush fleece with a dense, cloud-soft matte pile. it is not the thin, shiny costume fleece you've been burned by before. the fluff is the product.

no — it's real pajamas. thick plush loungewear you actually live in: movie nights, bed rot, 2am kitchen raids. can it moonlight as the laziest, funniest halloween fit of all time? absolutely. but it's built for every night, not one night.

the group chat is obsessed 💀

  • the mouth reveal ATE

    my face pokes out of a giant plush mouth and every single person i facetime loses it. also it's genuinely the softest thing i own. i did not expect both.

  • bought it as a joke. wear it daily.

    got the fish to be funny and now it's just… my evening outfit. the fleece is actually thick, like a wearable blanket. bed rotting has never gone this hard.

  • best gift reaction i've ever gotten

    gave the bunny to my best friend and she screamed, put it on immediately, and sent 47 photos to the group chat. if your friend is a bit of a menace, this is the one.
