Big Agnes - Mirror Lake 20 - Women's

The women's Mirror Lake 20 from Big Agnes is a traditional mummy-style down bag constructed with heat-trapping Insotect Flow baffles. Ideal for backpacking but versatile enough for couch surfing, the Mirror Lake is insulated with water-repellent Downtek™ and uses baffle construction for efficient heat distribution. If you’re in the market for a mummy bag constructed with high-quality, lightweight materials, this bag is your ticket to travelling fast and light.

What's in a Name?
Located in the Flat Tops Wilderness, CO, the trail leading to Mirror Lake follows pristine Mirror Creek. This beautiful turquoise lake with clear, still water makes the four mile uphill hump worth the trip. Virtually any caddis or mayfly patterns are bound to bring fish to the surface, so don’t forget your fly rod.
