This versatile bag is sustainably crafted with durable materials. Mountain Hardwear set out to prove that sustainability is about opportunity, not sacrifice. But there's more to the Lamina Eco AF sleeping bag than a little green here and there. In fact, there's no color at all. The Lamina Eco AF™ is undyed to reduce the brand's water footprint. And on top of that, it's made with a recycled shell, lining, insulation, and trims.

• Eco design features undyed recycled fabric, insulation, trims, storage and compression sack. 
• Proprietary, welded Lamina™ construction enhances loft and eliminates cold spots. 
• Recycled 20D nylon ripstop is lightweight and highly compressible. 
• Shaped draft collar blocks the escape of warm air from inside the bag. 
• Standard mummy cut is efficient, warm, and comfortable.
• Contoured footbox follows natural foot position for maximum warmth and comfort.
• Tailored hood comfortably blocks drafts and seals in warmth.
