This new Selk'bag isn’t just an update—it’s a game-changer. Designed for ultimate versatility, it has a mid-body zipper that lets it transform into a cozy jacket and bottom half.

Size Chart
A proper fit is essential to fully enjoy everything a Selk'bag has to offer. All Selk'bag models are unisex, meaning that they fit both men and women.
The size you need will depend on 3 factors:
- Your height (See recommendations below)
- Your waist/hip size (See Size Guide chart below).
The lower and of the height recommendations below are for people with wider hips/waist.
The higher end of the height recommendations below are for slender people. For example: A 5'5" slender person will most likely fit in a Medium, while a 5'5" person with wider hips will certainly need to upgrade to a Large. -
The activity you'll use your Selk'bag for the most: sleeping, being active or both.
For sleeping, if you're in between sizes, we recommend sizing up to make sure you have ample space.
For active use, if you're in between sizes, we recommend sticking to the smaller recommend size without wearing the booties. A less baggy fit might be better to move around without booties, but keep in mind if you plan on wearing the booties the sleeping bag might feel a bit short and 'pull' on your feet and shoulders when sitting/bending.
To help you choose we’ve put together the Size Guide below.
In case you're still unsure which size to choose, please contact us and we'll be glad to help!

IN BETWEEN SIZES?
A looser fit is better for a more comfortable sleeping experience, while a tighter fit is better for mobility while being active (but may feel tight on your shoulders if the booties are left on).
We always recommend sizing up if you are in between sizes or not completely sure. It's better to have a little bit more room than not enough while using your Selk'bag!
