When Vaude set out to make the Blue Beech 450 Sleeping Bag, it wanted to create a bag that was environmentally-conscious, both in materials and in manufacturing process. That's not to say that performance went on the back burner, because this puppy is built to give you nights of sleep out on the trail that are typically reserved for cushy four-poster beds and silk sheets; you get the idea. Built for moderate climate camping, the Blue Beech features a rugged three-layer construction with camel hair, Tencel, and recycled polyester. Vaude filled it with Sensofil Eco fill insulation and made sure that all skin-touching fabrics were exceptionally soft and up to Bluesign standards. A pillow compartment inside the hood keeps your nugget comfy, and a warmth collar lets you seal out the cold. An interior mesh pocket keeps your essentials handy and free from the clutter of your tent.
