Softest thing I own
The fleece is unreal — thick but not sweaty. The hood spikes hold their shape instead of flopping over like cheap costume ones.

Built for hibernating
Heavyweight fleece with a smooth lining that doesn't cling. Full-length legs, ribbed cuffs, and a hood that actually stays up.
Detail you can feel
Stone-texture print across the body, plush petal spikes with stitched fangs on the hood, and a metal zip pull.
Easy fit, easy care
Unisex S-XL with a relaxed cut. Machine wash cold, tumble low — the print and spikes hold up wash after wash.

Slippers make the set
Ordered the bundle and I'm glad I did. The petals on the slippers are stitched really well and the soles have grip on hardwood.
Marisol P.Verified buyer
Fit is generous
6'1" and the L has room in the shoulders and full length in the legs. Zip goes all the way up if you want the hood snug.

Cozy, runs a touch long
Love it for movie nights. I'm 5'3" and the S still pools a bit at the ankles — nothing a cuff can't fix.
Bree L.Verified buyer
Washed great
Cold wash, low tumble, third cycle in and the print and spikes still look new. Pockets are deep enough for a phone.

Gift that got screamed at
Gave this to my roommate and she wore it for two days straight. Arrived in about a week and a half, well packed.

Why we made it
SnugBeasts started with one idea: loungewear should have teeth. So we built a full-length fleece onesie with a plush spiked crown on the hood — the kind of thing you throw on for a cold night in and end up wearing all weekend. Same fabric, same fangs, now with matching slippers.
Care: machine wash cold on its own, tumble dry low, no bleach. Zip it up before washing to protect the spikes.
