I'd like to believe that I spent a good amount of the last 22 years camping or dreaming in some form or another, about camping. In those years, only at one point was I ever required to sleep at the "position of attention" and that was as a young recruit at Marine Corps Recruit Depot, Parris Island. Those days are long gone and so should be the un-comfort of a standard sleeping bag. Be it canvas and down or high tech materials one thing has remained the same for decades, the same lifeless shape of sleeping bags. I'm no cadaver, so why stuff me into a restrictive sack.

When I first saw the Selk Bag I told myself I must have the body-shaped sleeping bag. Exit the cocoon and enter the sleeping sack, with arms, legs, feet hands and a hood. Two zippers, one on either side to make entering and exiting the bag very easy. But here's the catch, once you're in, you don't need to get out unless the call of nature dictates otherwise. From the campfire to your tent, to visit your camp neighbors, to check on that noise. No exiting the Selk bag, the arms and legs allow you to move around camp fairly freely, never sacrificing warmth.

Speaking of warmth, there are various temperature ratings, the 4g is rated to 35 degrees. Personally, I felt  the warmth and efficiency of the bag to be greater than a standard cocoon. There were no "cold spots" where there is a void of body mass to bag space. The compression of the Selk bag is adequate and I can stuff this into the included sack and have to compressed to the same size and a comparable sleeping bag.

The Selk is not a "one size fits all", rather there are various sizes available, to fit various sized people (makes sense right?) At 5' 10" the large fits me well with little leeway in the arms and legs. The hood is a full hood with drawstrings, the hands have access areas which allow the full exposure of your hands or you can keep them contained and warm all within the Selk bag and secured in via a hook and loop system.  You can roll, stretch and articulate all within the comfort of your bag without being subject to the normal sparse leg and arm room in a standard bag.

Overall, the Selk bag has brought comfort, warmth and mobility to sleeping under the stars. My only issue is that the feet are somewhat "floppy", and I have to pick up on the legs sometimes to keep myself from tripping over myself. A simple engineered hook and loop strap has removed this burden but it would be nice to see this included from the factory.  The durability of the bag, the zippers and the stitching looks to be acceptable and with 4 months of use, no problems have been encountered. If you like to sleep freely, the Selk bag may provide you with sweet, sweet dreams.
