Size Guide
2.0 TOG Adult Sleep Onesie
The NEW 2.0 TOG Adult Sleep Onesie has had a redesign, and now features a fit that is more suitable for feminine body proportions, large front pockets, thumb loops in the cuffs, and a detachable hood. Whilst the new Adult Onesie's runs true to size, we recommend sizing up for comfort, especially if you plan on layering underneath.
Please note: Table below reflects the flat garment measurements. The new fit has been designed to standard women's sizing and is best suited to female (AFAB) body proportions.

- Samantha K.Verified BuyerReviewingAdult Sleep Onesie DaisiesI do not recommend this productRated 2 out of 5 stars1 month agoWanted to love it
Man, I’m so disappointed I really wanted to love this onsie especially for the price of it. Thought this would be the answer to all my co sleeping dramas but it just created more- every time I tried to sleep in this I would end up taking it off in frustration. For being 2.5tog I thought it would be warm (ac is only on 23) but no I still felt cold. I have quite a lot of the ergo products and I love the fabric and the amount of stretch… this onsie offers none of that, feels extremely tight and uncomfortable when trying to sleep in a fetal/ optimal position to feed in- it digs in and restricts you arm movements and you can’t comfortably use the thumb holes at any point. Sizing needs more work- offering a larger size especially since it is a ridged material would be great-I feel like all of the issues I’ve stated wouldn’t be a thing if I could have sized up.
