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.

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.

“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.
