"The" Onesies & Jumpsuits bench

A onesie exists for one situation: a room so cold that a two piece set leaves a gap at the waist every time you turn over. All of them here are fleece, all of them are warm, and several have hoods. This is the warmest shelf on the site and the smallest.

How it fits

Onesies are graded by height as much as by width. Between two sizes take the larger one, because a onesie that is short in the body pulls at the shoulder every time you sit down.

What it does not do. A onesie is not a costume and not outdoor wear. It is also the hardest thing on this site to get out of quickly, which reviews mention more than the warmth does.

Prices update on a schedule

Every figure on the site comes from our last update, and the date sits on the prices page.

Sizes are pages, not a dropdown

A size with no current price loses its page until the price comes back.

Fabric from the label

Fibre percentages and care come from the label sewn into each piece.

Ratings belong to the piece

Colours and sizes of one style share a pool of reviews, so we never add them up across the range.
