Squared-away warmth.

Weighing in at just over three pounds, the rectangular Big Agnes Storm King sleeping bag provides a lightweight and roomy solution for catching some z's when it's below freezing. Top baffles feature supremely toasty 650-fill goose down, while the insulation-free underside of the bag (where down would get compressed and lose its loft, and therefore its warmth) features a built-in sleeve that accepts a rectangular sleeping pad.
  • Big Agnes Classic Series sleeping bags have no ground insulation and are meant to be used with a 20in (51cm) rectangular sleeping pad for optimum warmth
  • Insotect Flow construction uses vertical chambers with interior gates that control movement of down so as to equalize insulation distribution for uniform warmth throughout the bag
  • Down-proof, microfiber ripstop shell fabric uses a water-resistant surface treatment to keep goose-down insulation dry
  • No-draft zipper tube, collar seals, and wedge between the bag and pad virtually eliminate areas of cold-air leak
  • Interior fabric loops attach to a sleeping bag liner (not included) that provides an additional measure of warmth or moisture-wicking performance
  • Left- and right-zip Big Agnes bags with the same zipper size can be mated to create one large sleeping space for couples
  • Built-in pillow pocket holds your fleece pillow or folded jacket
  • Note: compatible sleeping pad not included

Super warm!

Really warm bag. The baffling helps keep my toes warm in a rectangle bag. Compresses nicely and it's not to heavy. Love the pad sleeve.

Did a fine job!

I used this bag on an elk hunt twice this past week. From very cold temps of 24-36 degrees it kept me very warm and was very comfortable. A tiny bit of condensation got on it at the foot of the bag, but it did not affect the warmth etc.The bag dried very quickly in the morning sun. I was pleased. I am planning on exchanging it for the Blackburn only to save weight and bulk in my pack. My knees are telling me every once counts. There is a half pound difference between the two, but if you are not worried about weight or bulk, this is an awesome 3.5 lb bag

Will it work with the thermarest prolite...

Responded on

Yes, the big agnes bags will work with any pad that fits the BA pad dimensions.

Warm and light

I've only been able to use this bag once so far. It was high up on a windy ridge, 15f temps, no tent just a nylon tarp pulled over for wind and rain protection. I stayed nice and warm all night. I move around a lot when I sleep so I really like the air pad in the sleeping bag idea that Big Agnes uses. I was very comfortable all night. I'm 6'3" 195 lbs. the XL size fit me great.
