“If the weight and performance of your gear is important to you, I believe our sleeping bags set a new benchmark.”

3D and 2D NanoShell Technology
Sea to Summit has used a unique 3D Nanoshell technology to insulate, repel water, protect the down and improve loft. The 3D Nanoshell works as a condensation management system this is featured in the Alpine and Traverse bags only. The 2D Nano DWR finishes offers a super durable water repellent shell.
The Alpine, Traverse and Micro bags use 850+ Fill Power (Loft) Goose Down. The certificate that comes with each bag states that the fill power is actually over 900! The down is the very best quality available for sleeping bags. It provides the highest insulation for its weight and will last the longest. The Trek bags use a 650+ Fill Power Duck Down.
