The Kids' Trestles 30° Sleeping Bag is a roomy, mummy-style synthetic bag that performs in cool and damp conditions, thanks to Spirafil high-loft insulation. Its unique blend of large, spiral hollow fibers and small polyester fibers provides the exceptional warmth, softness, and compressibility of natural down while increasing moisture resistance. The anatomically shaped footbox minimizes heat buildup and gives kids plenty of room to wiggle their toes, flex their feet, and find a comfy sleeping position. The bag's top portion is built for maximum loft and warmth, while the bottom portion retains a blanket-like feel for all-night comfort and the 3D hood can be adjusted to optimize heat retention. Rounding out this excellent bag are an interior stash pocket, "feely" draw cords, dual hang loops, and a stuff sack that compresses for convenient packability.
