Hello everyone - I'm a long-time reader, this is my first post...

Some buddies and I are planning a trip in the end of May for an area of the AT in N.C. - We're planning to pack light and travel 15 miles/day for 4 days.

In the past, we have always hiked in the early spring, when temperatures are around 30-40 at night. However, with it being late spring, I'd like to leave the mummy bag at home.

Does anyone have suggestions for alternatives to a sleeping bag? Initial research has shown space blankets and fleece blankets. I'm leaning towards fleece, but wondering if that will not provide enough warmth.
