Triple Layer Down Filled Sleeping Bag
-60 Degree, down-filled, 4-season sleeping bag
The WARMLITE TRIPLE SLEEPING BAG is the only complete backpacking “bed” for ALL temperature ranges, providing comfort in all conditions, anywhere in the world.
Warmlite Down Filled Tri-Layered Sleeping Bags have THREE overlapping temperature ranges from -60° to +60°F (-75°F to -80°F reported by hardy Alaskans). An optional net top extends use to the tropics or insect prone areas. Making this a true 4-season Sleeping Bag.
A Warmlite Down Sleeping Bag has three layers that can be zipped on or off depending on the climate and conditions you will be facing. This bag gives the best comfort, warmth, adjustability, with least weight, through superior design, fabrication, and the most efficient use of materials.
INSULATION: This Sleeping Bag block all types of heat loss
- CONVECTION: Heat Loss is blocked by air-tight ripstop nylon, overlapping zipper layers, closely fitted collar and a fully adjustable hood. Air can’t enter the bag to carry away heat unless you adjust it to.
- CONDUCTION: Heat Loss is blocked by the highest loft 820-890 Goose Down available, held in a very uniform thickness that is not affected by your position in the bag. The bag is shaped for least surface area without compromising on comfort. Follow our girth measuring instructions to select a bag for best comfort. 3″ to 4″ less girth gives less weight but restricts motion, like a mummy bag, less girth isn’t practical for everyone.
- EVAPORATION: Heat Loss is blocked by flannel-like soft Vapor Barrier fabric on the bottom layer and collars, and your choice of Vapor Barrier fabric on the interior of the top layers. With collars snugly closed you get up to 15° more warmth from the Vapor Barrier layer. Open the collars and humidity escapes, removing the extra warmth. Vapor Barrier aids temperature control by giving extra warmth only when needed. We’ve used Vapor Barrier since 1955, and all Stephenson bags have had Vapor Barrier since 1968, a major reason for enthusiasm of users. The Vapor Barrier is as “breathable” as Gore Tex (as defined by their level of humidity transfer), and thus an excellent vapor barrier for this use.
Other Vapor Barrier gains:
Insulation always STAYS DRY. Meaning, the down in the sleeping bag that is keeping you warm will never become saturated in sweat. All bags without Vapor Barrier lining will get wet every night from inside, due to user’s sweat wicking away from their body and then condensing in the insulation.
Vapor Barrier helps you detect overheating quickly. You’ll open the bag to cool you immediately, not after the bag is soaked with damaging sweat, oil, and salt. The bag dries even before you’ve cooled down and doesn’t need hours of drying the next day.
It’s easy to clean with a wipe of a damp cloth.
Much less sweat is lost, thus you’re less likely to dehydrate or get frost bite the next day.
DOWN FILLED AIR MATTERESS
(Size 56”,60”,64” and 70” on DAM Refers to the girth size of sleeping bag it fits into)
Heat loss to ground is blocked with a 3″ to 4″ thick, full size 1 1/2 lb. Goose Down filled Air Mat (used since 1975), for the soft comfort and light weight of an airmat (which is usually cold), and warmth of Goose Down (in other bags Down is destroyed by lying ON it): no bulk and weight of covered foam pads (or those heavier “self inflating” foam cored air mats.) For less cost +1 lb. & much more bulk get the 2″ thick foam pad option (used since 1966), still lighter and more compact than “self inflating” foam air mats.
Our Triple Down Sleeping bags have a built in compartment to place a DAM or foam mat. With the pad locked to the bag you won’t roll off, or turn your insulation into pieces of cold non-insulating string by lying on it. The wider foam pad to fit in DAM space is ½ lb. heavier than normal foam pad and will need a larger carry sack.
We made the first Down filled airmat in 1959, learned to produce them in 1975. Net baffles block Down shift. Fabric is tough, heat sealed, coated nylon taffeta, the strongest used in any air mats. Performance exceeds all expectations, with lifespans of over 20 years. Color is orange for emergency use to attract attention. It can be used for a swim or fishing float or, will float the bag if the creek rises and floods your camp. It inflates fast with the carry sack used as a pump or the Camp-Tek Microburst Pump (never inflate by mouth).
RADIANT Heat is greatly reduced when inside a tent or under heavy foliage. The silicone coated nylon used on our tents is a great vapor barrier and is a standard on our tents.
LOTS of FOOT SPACE
After trying about every possible foot end design, we found that the simple extended foot space was best, allowing your feet to relax in a normal position no matter how you slept in the bag. Other “contoured” or fitted foot ends restrict foot spread and are uncomfortable for sleeping on your side or stomach. You can also put water bottles or boots in the bottom of the bag to keep them warm until the next day. The extended length of the bag allows you to do this without these items interfering with your foot space and sleeping comfort.
ZIPPERS
Even at the zippers there is no insulation loss. Parallel zippers separately close inner and outer surfaces. Separating zips on each side, and across the foot give independent venting and let you zip bags together on EITHER side, or join the tops together for a very wide warmth adjusting top. Use tops zipped together for a quilt on your cabin bed. In very cold conditions, to dress INSIDE or for fine tuning from -50° to +10°, using both tops, unzip tops on opposite sides to let the bag expand as needed.
In 1987 we switched to the excellent YKK zippers for bags, for least weight and least snags. Experience with these on bags since 1987 has been as flawless as on the tents since 1970. Heavy zips used by others snag fabric which spreads the slider and makes zipper come apart.
FULLY Adjustable HOOD
The unique Warmlite hood design evolved as a way to permit full head protection when sleeping in any position. Most hoods can only be closed if you lie on your back. Our hood zips up over the shoulders and snug up over or around the head with the top drawstring, so it can close snugly around your face or nose when you’re on your back, or adjusts to cover your head and leave breathing space when lying on your side or stomach.
For safety we use non-lock zip sliders; if you wake with your head in the bag, a good push will open the hood. Velcro tabs across the zippers at two positions take more than usual force to pass, so they won’t drift open. You can add tabs for more positions if desired.
Optional Net Top

Cost Comparison
The cost of a Warmlite bag may seem high, but consider how much it includes. Compare it to other bag combinations needed to match it, you would need a winter bag, a summer bag, an overbag, a Vapor Barrier liner, plus 4 lbs. of two self inflating pads to match the warmth and comfort of a D.A.M. Separately purchasing all these items would add up to a substantially steep cost, weight, and bulk not to mention closet space required for storage between trips. We give you more for by avoiding duplication of materials, low overhead, and no third party sales markup.
Many people don’t need extreme low temperature capability of a full TRIPLE bag, but want something for 3 season use where it might range from 10° to 65° F. The Warmlite Triple is ideal for that use, while no other single bag can cover such a wide range. The thin top covers 25° to 65° range, the THICK top -10° to 45° range, and the combination gives quick warm ups (and warmth enough for surprise emergencies down to -60° F. for average person.) Why buy 2 or 3 other bags to cover the range, not know which to take, or worse, find you’ve taken the wrong one, when one Warmlite bag does it all?
