Top 10 SL Down Sleeping Bag

Super warm, super light, incredibly lofty goose down sleeping bag with Thermium insulation at hips and heel.

The TOP Ten sleeping bag is rated for extremely cold weather; down to -70°C (-100°F). Yes, that's minus 100 degrees below zero. If you're planning on that, you need our Top 10 sleeping bag (and a sanity check).

The foundation of warmth comes from using 800+ FP goose down in deep, trapezoidal baffles that are welded, not sewn to provide consistent insulation throughout. For additional warmth the lining has silver threads to reflect heat, and we add Thermium^® insulation under the hips and heels.

To keep spills or condensation from wetting out the ultra high loft down the outer shell uses Dry Factor, the same waterproof/breathable 3-layer laminate used on our rain jackets. There are two zippers, a full length one on the right, and short one on the left so you can sit up and extend your hands to start the morning coffee while staying inside a cocoon of warmth. A draft tube extends the full length of the zipper, with protective webbing to prevent zipper jams. The snorkel hood cinches down to your face, and combined with a down collar locks in body heat without obstructing breaths of fresh air. For convenience, there's a chest pocket for stashing small items, and a pillow pocket for stashing extra layers to rest your head upon. All that comfort and each model packs down small and light in a compression sack.
