my fourth selkbag

Just love it Perfect for any situation either at home outdoors on a survival trip anywhere anytime I just give so much comfort. If I’m going to buy a fifth one I will buy one for myself if it’s made of water proof material and has a few more vents and more outside pockets for small tools. Pocket knife phone etc and is made of cold weather and perhaps a small inflatable layer for additional isolation.


That's so awesome.You are part of the Selk family for life now. Thank you for the support and the love Mark!

I’m a survivalist. I use the selk in the woods sometimes in a hammock and sometimes in a bivvy. A bought two. Original and the camo one. Both great. It’s a relief the movement freedom you have. The size is something I gladly give up in my pack (goose down is half the size) so all in all a huge five star ⭐️ from Holland!

Size Chart

A proper fit is essential to fully enjoying all the Selk'bag has to offer.  Please note, that the sizing recommendations are meant for people of average weight and sizing is impacted by user weight.  For example, a Selk'bag will fit a person of below average weight with a taller frame that exceeds the guidelines.  Likewise, a person of above average weight will require a bag meant for someone taller.

In-between sizes?  Please first consider the weight recommendations in the previous paragraph.  Second, please understand that a looser fit is better for more comfortable sleeping, while a tighter fit is better for mobility - but may restrict sleeping comfort if booties are left on.

We always recommend to size up if you are not completely sure. It's better to have a little bit more room while using your Selk'bag!

Please mind that our Original 6G model due to highest loft of insulation (contains more padding insulation that Lite 6G) makes it more snug, so we recommend to size up if you are 1'' to 3'' below the in between size range (i.e if you are getting the Original 6G and you are 5'9'' we recommend getting an XL)
