Technology

2D PermaShell™ Fabric is an extremely breathable, water-repellent 33-denier nylon with a DWR (durable water resistant) finish. This material is highly vapour permeable and down proof by construction therefore it does not rely on coatings that reduce breathability and add weight.

ULTRA-DRYDown™: is a permanent (no loss of treatment effect has been seen in over 14 wash cycles) Nano-level water repellent polymer treatment applied to Sea to Summit high loft, high quality down. The Nano-thin treatment vastly improves the down's reaction to water without effecting its weight or loft performance. ULTRA-DRY Down™ retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. Sea to Summit sleeping bags dry out 60% faster than bags with untreated down.
