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.

“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.”

Don and his son tried out two of the large side zip bivysacks on subzero outings this past year.
One was made with the mil-spec 30d nylon with a Durable Water Repellent finish. Not a waterproof fabric, it has a hydrostatic head (measurement of water pressure at the point of leakage) of over 400 mm.
The other fabric was a 70d ripstop nylon with a pTFE laminate on the underside. This is considered a waterproof and breathable fabric with a hydrostatic head of 3000 mm.
Both sacks used a silicone coated nylon bottom.
I asked Don to let me know about condensation and other considerations he discovered on using the two bivys.
Here is his report.

OWARE BIVYSACKS FOR WINTER USE
I tested two of the OWARE large size winter bivysacks, one with the High Vapor Perm PTFE fabric and the other in Durable Water Repellent ripstop. fabric.
One night the temperature was a few degrees below zero Fahrenheit. My son and I used the two biviys directly on the snow after digging and firming up by snowshoe compression the base. The bivy sacks’ large size easily accommodated winter weight mummy bags and double sleeping pads. They were great for fitting in clothing and the many items such as winter mukluks or boots, clothing, etc that are needed close at hand on a winter bivouac. I was particularly interested in comparing vapor transport between the two bivy’s.
I found that there was very little if any appreciable difference in frost build-up between the HVP bag and the DWR bag. I think that vapor transport in far below freezing temperatures ceases to take place if the fabric isn’t close to a warm body, in this case the sleeping bag. When the vapor left the sleeping bag outer fabric and hit the cold bivy fabric, it turned into frost,.
I found that the black , textured PTFE fabric tended to harbor frost and snow within the fuzzy nap of the fabric on the top cover and was hard to thoroughly brush off.
I decided to choose the olive ripstop , very slick bivy as my winter bivy of choice.
The insect netting at the head was not just unnecessary for winter use, but actually a nuisance, as the netting accumulated frost from my breath and rained it down on my exposed face and sleeping bag. Much less of a problem (though still present) with a head opening lacking netting. I will probably remove the netting in the future since the Oware Large Bivy will be used by me for only winter use.
Another factor to be considered in purchasing gear is the sewing. The seams were all very tight and with no wander. All high quality zippers and material and made in America!

Backpacking Tarps
The lightest and most versatile of shelters, and can be used for a place for teaching out of the sun or rain. Their set up can inspire craftsmanship among students. They are used by many major outdoor schools and savvy go light backpackers everywhere. Our tarps are available in various weights of nylon with a thick waterproof coat of urethane or an ultralight silicone coating. To add strength, sewn on webbing loops are used instead of grommets for tying the tarp out and are also reinforced with an extra layer of fabric at high stress points. Custom size tarps also available.
