Designed for users up to 176 cm tall, this left-zip mummy bag uses a differential cut and H-chamber construction to keep down in place and eliminate cold spots. The shell and lining are both made from Toray Airtastic, a 100% polyamide fabric known for its downproofness, breathability, and featherlight feel.
