Trusted by our military, and with a focus on saving weight and space, the SF (Special Forces) Series sleeping bags enable forces to adapt to unpredictable deployment durations - from a few hours to several days.. Specifically designed for use where reliability is required in harsh weather conditions, be it military operations or demanding outdoor adventures, the SF EXTREME is the first choice for extreme cold. SF Extreme sleeping bags are a 2 sleeping bag system, 1 outer SF2 sleeping Bag and 1 inner SF3 sleeping Bag. Combined together they can provide excellent thermal properties and offers reliable protection even in extreme cold temperatures upto -30 Deg Celsius. Despite offering immense warmth, this packs to only 45 x 22cm.
Constructed with a durable, water-resistant Nylon shell with a soft Nylon liner. These have the highest quality Down-like warmth, Supra-Loft laminated insulation which is water-resistant in itself to provide maximum insulation, loft, and compressibility. The outer SF2 (Special Forces 2) is attached to inner SF3 (Special Forces 3) via additional zippers so that they don't move while changing directions. Both of the sleeping bags have Three layer off-set construction featuring a contoured hood and wide semi rectangular shape, which help seal in your warmth.
Temperatures and usage conditions:
The SF EXTREME sleeping bag temperature ratings are determined in accordance with EN 13537:
-
- T-comfort: -25 C – the lowest temperature at which a woman can comfortably sleep through the night.
- T-limit: -30 C – the minimum temperature at which a man can sleep without discomfort.
- T-extreme: -37 C – the lowest temperature for survival in the sleeping bag. This value is not recommended for regular use.
Supra-Loft Laminated insulation
The inside of the sleeping bag is filled with Supra-Loft Laminated synthetic down, specially developed for Sper High Altitude use, which effectively helps maintain thermal comfort in extreme cold. The insulating material retains its properties even after contact with water, washing, or heavy use.
Anti Snag Zipper system
The Anti Snag system prevents fabric from getting caught in the zipper. Along the zipper, there is an insulated draft tube to block cold air. A Velcro flap at the top of the zipper prevents accidental opening. The trapezoidal footbox design offers more room for the feet and improves heat retention.
Easy transport and storage
When packed, the sleeping bag takes up little space – 25 x 35 cm, and its weight is 3400 g, making it easy to carry and minimizing gear load.
Integrated hood for cold protection
The model is equipped with a shaped hood with adjustable face opening that can be individually adjusted with drawcords to enhance cold protection.
