Hooray! Finally, a sleeping bag that is both warm AND comfortable. The Z Top™ sleeping bag has a unique top flap that comfortably seals in body heat and eliminates drafts. This revolutionary design allows you to sleep in the position you are most comfortable. You can even sprawl while keeping under the covers. In warmer conditions, you can fold back the top flap, or unzip and remove it.

In Kodiak Canvas fashion, this bag is constructed with premium materials and loaded with features. The top-of-the-line, locking, YKK zippers stay put and won’t travel during the night. Zippers are lined with anti-snag strips and have a full-length zipper baffle to reduce heat loss. Dual layer construction, with offsetting seams minimizes cold spots. A headrest at the top of the bag provides a comfortable area for head and arms. A pillow pocket helps keep a small pillow (not included) in place, or allows one to create a pillow by stuffing a sweatshirt into the space. A tech pocket provides a spot to keep a phone close at hand, inside your bag. The wedge-shaped foot box provides extra space, so toes don’t get scrunched. A zipper at the foot of the bag allows you to vent the bottom when needed. Roll up the bag and secure it with handy compression straps and snap buckles. It is made with a rugged water-resistant canvas shell, and a posh 100% cotton flannel liner. The efficient Factor-4™ insulation is a hollow fiber polyester that is light, fluffy, and very warm. A canvas duffel carry bag is included. Compatible with the Booster Quilt™ accessory (sold separately) that can boost the bag’s temperature rating by up to 30 degrees. Patent pending.

This regular size will comfortably accommodate sleepers up to 6’ tall and 225 lbs.

    Unlike any other!

    Posted by Andrew Rosen on 16th Oct 2020

    I had never really liked mummy bags but persevered with one because I used to pack everything on my motorcycle and the mummy bag would pack down really small. Now I load everything into my SUV and go glamping at the same location 12 miles off blacktop into the Black Hills SD. When I saw the regular rectangular Z Top sleeping bag on Youtube I thought it was ridiculous and just another gimmick. Because there were some good reviews I figured I'd buy one and unzip the Z-top part and use it like a regular sleeping bag. Well, sometimes I just love being utterly wrong!!! Last night was very cold, below freezing, and I had attached the Z-top part but was using it like a blanket. I finally figured I'd use it like I was meant to and wow, it is perfect!!! I could lay on either side or my front and my arms were still covered up. What a concept!!! Cold nights are cold no longer.....thank you Kodiak Canvas....

    I promise, using this bag has been the best sleep I've had using a sleeping bag ever. It's seriously so warm and comfortable, and the head flap is so nice.
