Using some pre quilted hollow fiber insulation and some Camo surplus nylon, sewed up a half bag. Fits over my down bag and ties to the side loops so it won’t slip off in the night. Allows extra insulation and weather resistance with minimal weight. My down jacket can serve as insulation on the top half.
Weighs 17 ounces.
Keeps wind, bugs, dirt off you and off of your nice down sleeping bag. Protects your inflatable sleeping pad and you from the damp ground. Great for Scout troops and schools, and those hard on equipment light, simple, inexpensive.
Super breathable top of 1.1 oz ripstop nylon. Waterproof bottom of silicone coated 1.1 oz ripstop nylon. Olive or Marpat digital woodland camo top, black bottom.
Drawcord closure at top. No zipper to wear out, you can draw it around your face to keep out drafts (especially nice for quilt users).
7.15 ounces in weight (7.4 with included tiny stuffsack) Roomy girth of 72″ from head to elbows, then tapering to 26 over it’s 85″ length (from opened top to heel). Drawn closed measures 80″ to heels. Squared footbox is 10″ high. This gives a 6 ft tall person 8″ total extra for your bag to loft on either end or makes it useable by taller folks in warmer weather.
Stake out loop at bottom to keep it in place when you are out of the bag. Reinforced tie out in middle of the top panel. Tie it up to keep the fabric off your upper body for more ventilation or bug resistance.

“This bivy is great and just what I was looking for and affordable, water resistant yet breathable bivy that will work really well for my 3 season sleep system. After using it quite a bit I really have come to like the draw top closure and not having to worry about an ultra–light zipper snagging on the fabric. It is very simple and does exactly what I need it to do.”

Just before Goretex burst on the scene, VBL’s
were more popular as they greatly enhanced the
usefulness of coated fabric rain gear etc. The most
popular undergarment of the time was the large
opening cotton string shirt. This worked really well
as it kept the VBL far from the skin but didn’t
have a lot of fabric for absorbtion. Even better
were the expensive wool versions.
One combination I have used with success is a half
bag of silnylon for the legs and waist when sleeping
combined with a VBL jacket. This way your feet
stay warmer than using VBL pants as heat from your legs can more easily reach them. It also can
double as a pack liner.
The jacket can be worn during the day and with the advantage of enabling you to layer coats over the top of the VBL for both sleeping and hiking.
I have found that a VBL jacket over long johns was comfortable with no noticable moisture buildup when hiking in sub zero weather
and balancing my outer layers
to keep from overheating.
Climbers on Denali wear
VBL vests under down gear when climbing to keep
their insulation layers dry next to their backs.
Been curious about using a VBL (vapor barrier liner)? Here is an inexpensive and light way to learn about their advantages.
Bring this shorty VBL on your next cold weather trip. At night use it inside your sleeping bag to add warmth.
For cold conditions, wear over long underwear and inside sleeping bag to retain heat and limit insensible perspiration. This will keep your sleeping bag dryer, hence lighter and warmer and also reduce the amount of fluids lost by the body at night, so you have to drink less (melt less snow too). Especially good on extended trips where it is difficult to dry the sleeping bag each day. Also carried by mountaineers and search and rescue team members for quick emergency shelter ( it slows heat loss due to evaporation, convection and radiation).
Possible other uses include slowing heat loss in emersion cases, as a wind sock for helicopter evacuations, as a pack liner, as a solar still, or to keep your bottom half out of wind and weather when on a stand or bivy ledge. Very compact and light. Folds to fist size.
This version is a half bag, just 52″ long. Made of silicone coated 30d nylon it is sturdier than a trash bag, plastic or mylar versions. Weighs under 4 ounces so there is no great weight penalty to bring it along and in fact your sleeping bag will not pick up as much condensation weight over time. And with a half bag, you can still wear an insulated coat on your top half. Just snug the elastic cord around your waist. Your feet will get warm air flow too, unlike socks which isolate the feet.
Custom sizes available.
