Big Agnes Shoestring SL 22 Sleeping Bag was named Best Synthetic Sleeping Bag in the Backpacker’s Gear Guide 2013, and the Gear Guide 2013 credits the new Pinneco Core® technology.
Backpacker’s Gear Guide 2013 appraised that the Shoestring SL 22 uses Insotect Tubic™ insulation system. Insotect Tubic™ combines the presence of Vertical Thermal Channel™ (VTC) and Insotect’s proprietary DualVault™ system component, alongside with the Pinneco Core® technology, into one complete insulation system. The tubular-shaped channels allows for the vertical and arched insulation fibers to deliver its maximum loft. Air is better trapped, and this system saves weight.
