ClimaShield APEX is the most thermally efficient synthetic quilt insulation avialable. It drapes, compresses and recovers extremely well and does not requiring through-stitching baffles to stabilize the insulation- that eliminates compressed sewn areas and prevents cold spots. Many other synthetic insulations require sewing of the insulation to the bag shell (you can see the many horizontal seams on the outside and/or inside of the shell) to prevent shifting or tearing. Apex is a modern continuous long staple type of insulation and does not need quilting in this type quilt and retains all of it's thermal clo value. - Some synthetic insulations made for small panels in clothing that that test good clo ratings loose much of that thermal efficiency by quilting to stabilized the fragile insulation matrix - Sewn through insulations generally can not recover as well to multiple tight compressions over time.
Large foot box for more comfort vs other light weight quilts and bags. Allows the use of insulated socks, booties or other clothing in the foot box with out compression formed cold spots.
MLD Endurance 10d X 10d 3xDWR The very best lightweight sleeping bag fabric available. It has a high thread count density for strength. See Fabrics Mojo Page. Our 3xDWR shell and lining fabrics are an important part of the thermal equation. The liner and shell are tuned for air permeability to limit condensation and slow heat transfer to boost the the overall warmth rating.
Can be used over ALL other bags to boost temp ratings because the foot and leg circumference can be adjusted - unlike a fixed foot box quilt. Use it over a 2 or 3 season down bag for full winter temps. The leg and foot area snap points have webbing loops that can be used with bungee for setting it wide over a high loft inner bag. True variable girth over the entire length. This system also helps keep the down inner bag dry. In below freezing weather- insensible perspiration from your body cools as it moves through the sleep system and condenses back to liquid water near the colder outer surface. By using a synthetic quilt over a down inner bag, the down bag stays dry and the synthetic quilt dries fast and retains most of it's insulation when wet.
• Hammock Under Quilt Use Ready : Corner webbing loops for use as a hammock under quilt.
• Foot box and lower leg area is larger than many other lightweight quilts. Body mapped shape offers warmer torso area and less bunching at the neck.
• Anchored no-fumble cord locks at each end.
• 24" soft velcro strips make a tight seal for lower legs and allows variable venting and full open use as a flat quilt or hammock under quilt. Also dries much faster when fully open.
• Removable dual sided adjustable back strap. Back strap has a long webbing to secure under a sleep pad. Sleep pad elastic clip on connection system supplied to make it easy to clip the quilt on and off of a sleep pad if desired.
• Quilt can be reversed to use inside out if one side gets wet.
• Head and Foot elastic cord sleeves.
• Foot box vent plug for the Spirit 28 and 38 - Prevents heat loss through the tiny gap after cinching the foot box closed.
Many users of the Spirit 4 quilts also use it over a 3 season down mummy bag to extend their system to 4 seasons. - Body produced moisture that can condense in any sleep system is then more likely to condense in the outer synthetic layer where it is more easily manageable.
