Hello survivalists of reddit.
I am preparing for the High Lonesome 100, a big mountain ultra trail race in late July here in the Sawatch Range of Colorado. Part of the required kit is an emergency bivvy.
I have to carry this during the crux of the race: Climbing Mt Shavano (14,231 ft) in the middle of the night, after having already run 60 miles, so weight is a huge consideration.
The race director has recommended the SOL Emergency Bivvy which comes in at 3.8 oz
I have been looking around for something even a tad bit lighter, even if only getting down to 3.7 or 3.5 oz.
Any recommendations would be greatly appreciated
I would take a look at a Tyvek ultralight bivy sort of like 3F makes, would definitely want to use a poncho for a ground cloth if the ground is wet or damp though.
The SOL Emergency Bivy has some insulation sort of like mylar emergency blankets, so it will be both somewhat warmer and more water resistant.
