Monster Onesie Pajamas Adults Hooded Flannel Unisex

A full-length flannel suit with a cartoon monster head for a hood — an oversized open mouth across the crown, and a matching face patched onto the pocket. What separates it from a costume is the cloth: this is thick flannel at a real pajama weight, so it survives a whole evening on a couch rather than twenty minutes and a photo.

Key features of this hooded monster onesie:
- Thick flannel body at a fabric weight of 7.4-8.8 oz/yd² (251-300 g/m²)
- Polyester fiber (Terylene) and flannel
- Oversized monster hood with an open cartoon mouth
- Cut for both men and women, sizes S through 2XL
- Nine designs, from plain colors to fish and rabbit characters
- Matching shoes included

Sized by height and body weight rather than by chest measurement — the supplier's chart runs in pounds and inches, so read it before choosing a letter.
