Sea to Summit  Trek Down Sleeping Bag - TkIII Long

Sold Out

Traditional comfort and value, with an anything but traditional design approach, the Trek™ Series sleeping bags are the first choice of adventurers looking for maximum versatility in a moderately-priced sleeping bag.
Available in three different fill weights and three sizes, including Regular Wide.
Vertical baffles over the chest prevent down shift towards the sides of the bag during sleep, and the side block baffle construction maintains the 60/40 upper to lower fill ratio. The 3D sidewall baffle ensures that the down can loft to the very edge of the bag, and the hood and oversized draft tube help retain warmth. Lightweight fabrics – including a soft-touch 20 D Nylon lining - reduce weight and packed volume.
The full-length two-way #5 YKK side zip and secondary footbox zip offer unparalleled ventilation and allow the Trek to be used as a quilt. Zippers are backed by an effective anti-snag material.
A large internal pocket, perfect for keeping valuables close or batteries warm, completes the thoughtful design.
