Going light on weight doesn't mean sacrificing comfort. Cocoon's Air-Core Hood Pillow weighs less than 4 ounces, packs down to 4 x 3 inches, and sports a soft microfiber face. Built specifically for use in the hood of a sleeping bag, the Hood Pillow's contoured half-moom shape prevents any bunching up or movement when used inside a mummy bag.

The inflatable air core is bolstered underneath a thin layer of synthetic filling for added softness and warmth. The twist valve lets you dial in the firmness and to make more room if you need to cinch the sleeping bag hood tighter on cold nights.

We love the reversible cover with microfiber on one side and nylon on the other. The microfiber provides added warmth on cold nights, and the cooling nylon side is built for summer camping, making it one of the more versatile ultralight inflatables on the market.

Pros: 

• Tiny packed size
• Shape is ideal for mummy bags

Cons: 

• Nylon side sticks to face on sweaty nights
