It's a fact!!!  Down sleeping bags are simply the most comfortable, lightest, and most compact-able sleeping bags out there. but the fact is, down bags are extremely expensive these days, and most people think that down is too hard to take care of, so to help keep costs down and help keep the benefits of down comfort, and warmth we have "brained up" our all new  "downX" sleeping bags. We've taken our best selling down bags and made them the next generation of backside backpacking HI-TECH performance sleeping bags. Now you get our extremely popular Xfiber on the bottom that insulates even if it gets wet, and the super soft comfortable down softness on top! talk about a great idea...

YKK zipper
Many manufacturers do not offer the luxury of a solid YKK zipper. WE DO, we also went a step further and used a self locking zipper on our sleeping bags that won’t keep sliding down in your sleep.

Breathable Diamondtech
is water & wind proof material that is incredibly lightweight, soft and a downproof thread count Micro-Fibers as a shell for our bags. Diamond tech MicroFiber fabric threads and filaments are tightly packed so air spaces are few and too small for wind and rain to breach. Each fiber is treated separately before it is stitched which builds the water & wind proof characteristics.

Insulation
We use premium 600 in our down bags.

Wider Means Better
A good nights sleep is critical for the physical restoration that your body needs in order to enjoy the next day's adventure. You won’t wake up feeling cramped in our bags.

Compatible Zippers
All Backside sleeping bags come in both left & right zippers to allow them to zip together side by side.

Super fat draft tubes
come standard issue with all backside sleeping bags. Our draft tubes run the entire length of the zipper and up around the collar to keep warm air from escaping through the bag’s zipper.

Totally FREE Compression sack.
Just another reason why you should choose the backside products. All of our sleeping bags (other than our fleece bags ) come with this.
