Big Agnes System Bags
Our Big Agnes System sleeping bags attach your sleeping pad to your sleeping bag, for a more comfortable night's rest.
Insulation requires air to work effectively, and lying on top of the insulation in a traditional sleeping bag renders it ineffective. With any sleep system you'll want a properly insulated sleeping pad to keep you warm against the cold ground. Our System sleeping bags feature no insulation between the sleeping bag and pad - this not only saves weight and bulk, but makes for a more comfortable sleeping surface, without lying on top of clumped, ineffective insulation.
Big Agnes System bags keep you secure on top of your pad at night - no more rolling off of your pad onto the ground! They also tend to provide more room than a traditional mummy style bag, and reduce friction noise between your sleeping bag and pad.
All Big Agnes System bags require an appropriately insulated sleeping pad to create an effective sleep system.
