Need something for a spring and summer. I dont need anything sub zero. Just a good roll I can take anywhere, for less than $100
You may hear this again but as an infantry guy who loves to backpack/camp/survival trek, I like the surplus USGI system. Its not the lightest or smallest but it's modular for whatever condition and with the bivy component, you really only need a small sylnylon tarp to hang over your head and shoulders and you can weather any conditions minus maybe the arctic. While its far from perfect....what really is? It does everything well. Oh and when its chilly I carry a small pad to get off the ground or just pile up leaves to prevent conduction.
Another vote for the USGI system. I comes with a heavy bag, a light bag, and a bivy cover. While it is not the most lightweight gear, I think it makes up for that in durability.
My set up in winter is to carry the black bag with the bivy cover, and then in spring/summer/fall, carry the green bag with bivy cover, also get a new stuff sack. This will help to keep the weight down.
This is where I got mine from, and for the price its hard to beat.
I concur with the USGI bags. Last year I did 4 nights in the Rockies in August, but where i was got to 37 at night. I only used the black bag in my hammock and i was as toasty as i could be.
I've been eyeballing this bag. Its a little bit above your budget ($114), but it's lightweight (1.5 lbs.) and I like the look of the dual zippers.
That outfit is a local shop that has great prices.
