Description

Ultra-light and technical, our Flame™ Series bags are designed to
keep you as warm as possible while minimising packed weight and
size.

The Flame™ Series spans everything from an ultralight liner to
an expedition weight mid-winter bag. While the end usage is
very different, they reflect a design ethos of matching weather
conditions to the lightest bag possible.

The secret to the impressive performance is a combination
of premium materials and careful design. The RDS 850+
Loft premium goose down, light-gauge #3 YKK zip and high
performance 10D Nylon shell and 7D lining fabrics set the stage
for superior performance. These materials are combined with a
contoured mummy design for efficient insulation, and that mummy
design is then tweaked for each model to best fit the use scenario.

The women’s specific fit is wider at the hip and narrower at the
shoulder and we’ve added extra down overall for increased
warmth.

Our ULTRA-DRY Down™ water-repellent treatment protects the
down from external moisture and condensation from the inside
of the bag, virtually eliminating the negative effects moisture has
on down. All Sea to Summit Down Sleeping Bags use Responsible
Down Standard (RDS) certified down. The ULTRA-DRY Down™
protection also makes the Flame™ an impressive hard-alpine or
adventure racing bag, where every gram is counted and down has
never been a viable option.
