Hooray! Finally, a sleeping bag that is both warm AND comfortable. The all new 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.

    Loved the features when I saw the video, way exceeded my expectations when I used this bag for the first time on a 3 day camping trip. BEST SLEEP EVER! Stayed warm and cozy! Actually hated getting out of my warm bag into a cold tent! Highly recommend!

    Good product

    Posted by Dan on 15th Sep 2020

    Tested in 40 degree temp with no complaints. Paired it with a 2.5" R6 sleeping pad. Actually had to open it up to cool off a couple times. Z top eliminates any cold air coming in and can only be used when temps are closer to the prescribed rating. Long enough for 6' 5" with room to spare. Extra foot room at the bottom was a noticable luxury. Rolls up nice and retention straps are quality. Carry/storage bag is not undersized and zipper is designed for easy and quick stowing. Definitely a comfort item not for backpacking (bulky and fairly heavy). Haven't owned many other sleeping bags to compare it to but so far I'm impressed and excited to use it in more extreme conditions.

    Best sleeping bag

    Posted by Bryan Peterson on 17th Oct 2019

    I bought 2, one for me and one for my nine year old boy. We camped out. It wasn’t very cold only around 40. I stayed very comfortable and a little warm but that is much better then being cold and my boy wants to sleep in it every night. What a wonderful design thanks to you Kodiak .

    Super Comfortable

    Posted by Scott on 28th Oct 2018

    Wow, this bag is super comfortable and warm. Very innovative. With the matching blanket and a good pad underneath it, it was about as comfortable as my bed.
