Winter Emergency Bivy Sack | |

I am looking for an emergency bivy sack. Not to be used in conjunction with a sleeping bag but solely for emergency use for planned single day climbs. I currently have an Adventure Medical Heatsheets bivy sack but I do not think it will be sufficient for winter climbs. I don't care about bug netting or any frills. As with all bivy sacks condensation issues are a worry esp. for the winter for an emergency bivy sack. I don't want to have my emergency gear causing more harm then good.
I was looking at something sub $150 if possible. Lightweight is a must. I am considering the Wild Things Half Bag $85 (military price) , Integral Design Micro Bivy ($157) , Black Diamond Winter Bivy ($89.95). Any other suggestions?
What do other people carry? Or suggest for an emergency mountaineering bivy sack?

I've personally used
This product doesn't exist.
It's def. a no frills style design, 9oz. The insulation is reasonable but I wouldn't leave behind your heavy jacket because you brought this along.
I used it while climbing the Grand Teton. The next step up would be Bibler which is Black Diamond's high end tent line.
is there 4 season bivy. But this comes at a large price and weight increase.

I was looking at the winter bivy. BD informed me that it is NOT waterproof. I went with the Integral Designs South Col event.. I got it on sale for $185.

With Epic fabric, BD doesn't tape the seams. Most of their tents recomend sealing the seams with Seam Grip to make them waterproof. That may be the discrepancy.

BD says winter bivy is not waterproof. They said the bivy is designed for emergency use only. Their words, not mine.

Glad we agree.

So the BD Winter Bivy is suggested and Integral Design Bivy's. I hope I can find something near $100 that is still lightweight and can be used for an emergency. I'll look more into the suggested bivy sacks though.

Rab Storm Bivy, Marmot Alpinist Bivy, MontBell UL Sleeping Bag Cover, and the REI Minimalist Bivy look like decent options too.
For the most part all reasonably priced and lightweight. I hope that if a bivy is lightweight it doesn't necessarily effect the durability of the bag. That's something to consider especially for winter emergency use. Anyone use any of these bivy sacks before?
Possible Choices:
MontBell Breeze Dry-Tec UL Sleeping Bag Cover- $120 (6.3oz)
Adventure Medical Kits Thermo-Lite 2.0 Bivy- $27.95 (6.9oz)
MSR-E Bivy- $68.95 (9oz)
Black Diamond Winter Bivy- $89.95 (9oz)
REI Minimalist Bivy- $64.93 (15oz)
Marmot Alpinist Bivy- $124 (14oz)
Rab Storm Bivi- $73.74 (17oz)
Integral Designs eVent Micro Bivy- $157 (18.5oz)
Wild Things Half Bag- $110 (29oz)

MSR E-bivy
I wish I could say I bought mine. After two cold nights in the Absorkee Mountains of Montana, I and fellow S&R with his bloodhound came across the hiker and got him off the mountain. He'd been so scared when he got lost and happy when that dog licked his face. He left his gear behind swearing to never backpack again!
The night time temps after we got the callout never got below -10 or above 15 degrees. He had hovered in that bag, ate the last of his food and couldn't even think to melt snow for water.
I figure if that bag could save his life, then I'm not letting go of it. To repay him I'll go to his hometown in Basin,MT and take him kayaking every spring since. Trust MSR

Another suggestion for a bivy...
botachtactical.com/mpiexproteem.html
A very lightweight solution that was recommended. Yet it still seems similar to the Adventure Medical Thermolite 2.0. It is waterproof and windproof. And radiates heat back to the body. But I still worry about durability with this type of bag. Input?

Thought i'd post another option I found for anyone's interest.

Blizzard Bag. Might be a good emergency bivy sack for some.
