Go ahead, stretch out.

There can be a lot of cringe-worthy aspects to sleeping bags. They’re too short, not warm enough, the zippers can catch, etc. The Marmot Radium 20 Sleeping Bag aims to ease all those qualms. The cold won’t hinder your slumber since you’ll stay cozy warm with the 650-fill insulation with an EN-tested 20F comfort rating. The hood has a drawcord to keep all that heat in, for ultimate comfort, while the Down Defender-treated insulation resists water so you can stay dry and warm even if the ground is not. The only thing worse than waking up cold and wet is waking up trapped in your bag. Fortunately, the two-way zipper with an anti-snag slider and zipper garage makes it a breeze to get in and out of. So go ahead and enjoy your sleep whether you’re on the trails or out for a weekend adventure.
