Sleeping in a bivouac sack in bad weather is never quite as comfy as sleeping in a tent, but I like to carry a light backpack, so despite camping in skies that looked like this…
…I once chose only to carry a very lightweight bivouac sack for a few nights out above Chamonix in the French Alps. My backpacking companions, however, chose more wisely:
My sister carried the one-person tent pictured on the above left, and her two friends chose to carry the burly two-person mountain tent on the right. I plopped down my bivouac sac between them, hoping that their tents would provide extra shelter from the elements, but I woke up–flooded out–in the middle of the night when rain streamed off of their shelters and straight on top of me! This is how I felt the next morning:
But, I wasn’t deterred. And I planned for a better shelter the next night. First, I set up my bivouac further away from their tents, and I also stretched a tarp across my trekking poles to deflect rain.
However, I knew the comforts of that two-person tent (even with three people!), and as soon as the rain started falling, I jumped inside:
On this trip, I had two bliss-less nights in a bivouac sack, but these lightweight shelters truly are amazing–in an emergency situation, on a rainless summer night, or anytime you don’t want to slog around with a heavy tent. But despite the benefits of going ultra-lightweight, I’d recommend a model with a pole or a moldable wire support to keep the material away from your face and to create a way for rain to slide off of the sack’s exterior while you sleep (more) soundly inside.
