Just joined here to see if I could get some expert advice—yeehaw! I've got a chance to buy a sleeping bag at a considerable discount, and since I desperately need a good bag, I'm doing a lot of research to see which one I should go for.
Basically: I know I want an ultralight bag, since why carry the weight if I don't have to? :) Also, I am planning on thru-hiking the AT in a few years, so I figure I might as well get as light a bag as I can.
I'm debating between a 15* rated bag and a 30* rated one; I sleep cold, but don't mind using layers, and I don't know that I'll do all that much winter hiking, to be honest, so I'm leaning towards a 30. I'm in Northern California right now (so think trips to the Sierras) but soon enough will be back east, in Connecticut, where three-season hiking can get down to the thirties or even twenties...
So here's what I'm thinking, and here's where I'd love your thoughts, o forum members! I was originally going to go for a WM Ultralight, but turns out I can't get a deal on that one. So then I looked into Marmot. I see the Plasma line is winning a bunch of awards and getting some good reviews (though not always 100% stellar) which prompts me to ask: since this is my first UL bag, and I'm thinking of it as my one real bag (I don't do enough camping, alas, to justify having more than one) should I go with the Plasma or the Helium? I know the Heliums are hugely popular, with good reason. But if you were going to buy a bag today, which one would you choose? (Or another one entirely?)
Thanks ever so—I appreciate it!
