SEA TO SUMMIT FLAME FMII 2019

Made with a 100% recycled Hydronaute XT-R Shell and a 100% recycled silk-touch Nylon lining. Available in Standard, Women's & Extra-Large Sizes. The Warmlite XT-R 550 is appropriate for temperatures of -1°C to -7°C.

With a technical shell fabric and high loft down but only the essential design features, the Warmlite XT-R Series provide warmth in cold to extreme cold at a very reasonable price.

The Warmlite XT-R Series feature a contoured 3D hood, box walled baffles, 3D draught tube along zips and premium 750+ loft water resistant down.

800+ loft DWR treated duck down is our premium choice – a must for the gram counters. This high-lofting white duck down delivers luxurious warmth at a fine feathery weight. This down has excellent compactability and loft recovery.

Down is the best insulation for lightweight sleeping bags due to its loft, compressibility and durability. However, this golden fibre has a failing: its ability to insulate drastically decreases when it is wet.

The solution is now here – DWR DOWN. This down has been selected to meet our rigorous standards, with a durable water-repellent (DWR) treatment applied after the cleaning and sorting process.
The benefits of DWR DOWN are:

• It absorbs less water in damp conditions
• It retains higher loft (insulation) in damp conditions
• It dries faster

Bungle sleeping bags are filled with 800+ loft DWR Down for greater weight saving.

Altitude AtII Women’s Sleeping Bag

Engineered for women to provide extra warmth where needed, be prepared for the unpredictable with our adaptable Altitude™ Series bags.

Thermolink

This bonded fibre weighs less and packs down smaller than competing synthetic fills, making our bags lighter and more compact while maintaining comfort and durability. The secret is in the manufacturing process: thousands of hollow fibres are sandwiched between a high-density thermal barrier and a fine, soft, body-conforming radiant retention layer to form one continuous sheet of Thermolink fibre. As it is one continuous layer, there aren’t any gaps for heat to escape, leading to better performance than traditional baffled fills.

Sac sleeping bags are made using lightweight and highly breathable 20-denier Vapour Vent fabric. This strong, compressible and highly breathable fabric uses a tight weave that keeps the insulation in but allows water vapour to escape. This reduces the possibility of clamminess and allows the insulation to loft fully for maximum performance.
