On a recent hike over Memorial Day weekend, when it was hot as crap in South Georgia, I brought my regular sleeping bag. The first night, I was so hot I slept in pretty much nothing and just laid out on my foam pad, but around the wee hours, I got a chill. I wouldn't call it legitimately "cold" but just enough of a chill to be uncomfortable and wake me up so that I had to find a ladies tree. No good. The next night, I did the same but pulled my PJs out so as soon as the HOT left me I put on some clothes. Same thing happened. Mind you, days were in the 90s and nights in the 70s. I was just thinking I wasted a lot of space and weight bringing my big bag in the summer but... still I needed something on me. The last night I just yanked my bag, still all zipped up, over on top of me and I was comfy.
I said all that to say this... I am looking for a super lightweight something to take on summer hikes when I just need a something over me to knock the chill off. I was look at the SOL Escape Bivy. 8.5oz. Reflects heat. $60. How does that sound for an option? Does anyone have any experience with these? The ones I saw said it was breathable, so less condensation issues. Sounds reasonable unless someone has a horror story to share.
