Trek Tk I

The Trek is cut broader than a mummy bag to give you room to move. The side zipper + footbox zipper are great for ventilation and allow the bag to be opened and used as a quilt, opening up a world of possibilities for camping and travel in warmer climes. The Tk I is the lightest in the series.
