Product Description:

The Extreme Cold Sleep System has two versions, 1) the Red Dot Design award winning, standard edition and 2) the Military Sleeping Bag System. This system was designed to provide the thermal protection required to adapt to tropical, subtropical, temperate and polar conditions. Each of the two systems are made up of 3 components, that can be used individually or in combination of one another to make the complete system. The first layer is the hygiene liner, second layer is the down bag and the third layer (outer shell) is a synthetic bag. These components can be used in any combination depending on your environment, however, recommended to always use the synthetic bag as your outer bag to improve moisture prevention. The system is made with a draft collar, which is an insulated collar that can be tightened around your neck that prevents the “bellows effect” in which conductive heat is lost when air moves in and out of the bag as you move around inside. This system also has a draft tube to prevent the significant amount of heat that is lost through the zipper of sleeping bags. To minimize this heat loss an insulated tube was added behind the zipper.

An instruction manual is provided that includes key procedures for replacement and other general maintenance that may arise, including cord replacement descriptions if required. (Photos included). Proper sleep method and packing order will be highlighted here.

Always inspect your system before each use to ensure proper functionality.
Things to look for:
– Tears in any of the components of the system
– Fraying or damaged cords
– Broken Cord Locks
– Ensure zippers function properly

Do not wear damp clothing inside the system, this could get moisture trapped in the bag, down is a great insulator, however loses its insulative properties when it gets wet. The down used in our sleep system and other down products has been coated to help prevent heat loss and loft when damp, however, it is still prevalent. The synthetic bag however, will not lose its heating properties if damp and is suggested to be used as your outer bag for this reason.

To clean: wipe clean with a damp cloth and mild soap (not detergent) and hung to dry. Do not leave bags wet. Allow bags time to dry before packing them into compression or stuff sacks for storage. Use a sleep pad to prevent ground moisture buildup and prevent punctures.

Warning: Always leave face exposed, DO NOT burrow into the bag, wear a balaclava if needed to protect your face from the cold. Not only will this increase suffocation risks by burrowing into the bag, the moisture from your breath will build up in the bag and reduce the insulation properties as you sleep. When paired with a bivy bag make sure outer zipper is left slightly open 4-6” to allow for air circulation.

Materials:

Outer shell: Ripstop Nylon
Insulation: 850FP down and Primaloft synthetic insulation (Depending on system component)
Liner: Taffeta lining

HANK = High Abrasion Neoprene Kevlar laminate, the materials used for the closure and cord management system on each bag.

List of hardware with part numbers listed on page 17 of manual for replacement parts if needed.

Features:

Low shear closure on each bag – (why is this better? – standard hook and loop requires a lot of force to pull apart in shear, (what is shear?) our loop was chosen specifically due to its low strength in shear, making it much easier to pull apart and open the bag. (This is critical for our quick egress patented system to exit a bag during emergency situations)

Anti-Snag zipper system – (what is this? – waterproof, lightweight zipper guards are added to significantly reduce zipper snags, greatly increasing speed on ingress and egress.

Hanging loop – at base of zipper there is a hanging loop to hang the bag for it to air out and dry.

Cord management system – (what is this?) this keeps cord locks and cords in place and easy to find in the dark. Cords are directed by the management system to face into the bag so the user can tighten and loosen the hood, neck, draft collar effortlessly from inside the bag. We use two types are hardware to distinguish between adjustment points (what hardware is used for what?)

Zipline Orbit Pullers – (what is this?) – oversized O-ring shaped zipper pullers for easy grip, even while wearing gloves.

Additional Safety – (how?) – as mentioned above, the patented system for quick egress in emergency situations, we added a feature that the zipper ends 2” short of the top of the bag to allow for the bag to open easier. The user is able to “slam” their arms to the side from inside the bag hard enough to cause the hook and loop to shear open and the zipper to pull open enough to assist in exiting the bag. ** without damaging the bag.
