Trueloft insulation is lightweight, compressible, and quick-drying, and traps more warm air between its micro fibers than traditional insulations with the same loft. Additional features include: outer fabric in silky diamond ripstop polyester; inner lining made with a warm-touch brushed Pongee polyester; #5 two-way nylon coil self-healing zippers, draft tube, compression stuff sack with YKK buckles.
