The concept of a “camping blanket” may seem silly, but trust me, once you add one to your camping kit, you’ll never go back. Perfect for keeping your backside cozy at the campfire, adding some warmth to a two-season sleeping bag during that third season, or even just getting comfortable at home on the sofa or on your friend's couch while traveling. We’ve rounded up our top picks for best camp blanket in the past, but now, OG outdoor blanket maker Rumpl has reinvented the game with this new Mountain Hardware collab.

Dubbed the Mountaineer, the Rumpl x Mountain Hardwear down blanket is made of the same innovative materials as MH’s legendary Ghost Whisperer jacket—a staple in my kit, and most everyone else in the outdoor industry too—making it the lightest and most technical down blanket ever made.

We’re talking hyperlight 7D Ghost Whisperer ripstop with DWR coating combined with 800-fill Nikwax hydrophobic down insulation so it remains lofty and functional even when moisture is present. The blanket weighs right around 12 ounces and packs down to about the size of a Nalgene, making it perfect for travel.

Adding to the functionality is 3M reflective piping and branding, corner loops for staking down if needed, and a detachable emergency whistle fixed to one corner. And it’s machine washable, so you don’t have to relive every memory with every use.
