Summer is the best time to backpack.

The Big Agnes Cross Mountain Sleeping Bag is warm enough for summer camping trips and light enough for backpacking adventures. Its Insotect Hotstream insulation uses recycled materials to warm your blood after sunny days by the lake, and it stays warm in case the summer rains start to fall. Big Agnes treated the shell to shed raindrops as well as other liquids.

Like most Big Agnes bags, the Cross Mountain has an un-insulated sleeve for the perfect pairing with 20-inch sleeping pads. The hood has a unique toggle that un-cinches for summer's warmest nights, and the vaulted footbox adds room for even more comfort. There internal loops for liners, and external loops for letting the bag air out. Big Agnes included sacks for camping and storing.

What do you think about this product?

Have questions about this product?

What's the widest sleeping pad that will fit? Also, isn't it reasonable to not use the sleeve and just sleep on top of the pad? Possible to roll-off in that configuration, but other than that, I don't see a difference.

Hey, Jeff the regular bag will fit a 20" wide pad. And it is totally reasonable to not use the pad. I never do use my pad sleeve, and usually don't have an issue. I suppose I don't move around much when I sleep though. Let me know if you have more questions!
