Rock Wren Nano

Write A Review

The zippered arm holes of the Wren series allow you to essentially wear your bag like an uber-warm parka when you're perched 10 pitches up, while the two-way center zip provides a convenient opening to remain tied in while you sleep. Trips out of the tent in the wee hours of the morning are no longer a matter of necessity overcoming endurance; the Wren's drawcord bottom the bag can be opened up and easily slipped above the waist.
