Still the warmest and most
compressible insulation available
GoLite
uses premium quality 800- and 600-fill power goose down. Down is still
the most thermally efficient insulation available, i.e. it provides
more warmth for its weight than any other insulation available. Down is
also superior in its drape, comfort, lifespan, and compressibility.
Nature is an incredible thing.
Unmatched warmth-to-weight ratio: down’s fine
filaments reach
out into its surroundings and create dead air space that slows the
escape of warm air, doing it better than any synthetic.
More compressible and durable than synthetic insulations,
and it retains its loft better over time.
