i've been reading up on thes things. i want to make one. weight is not a problem but packed down size is. not hiking but riding a m/c--not much xtra space.
1. why is the length 60" ? won't head and feet get cold?
2. i have a couple old sleeping bags. if i cut and sew them to DIY specs, will they work just as well sa made from scratch?
3. if the bottom quilt works out, should I use a top quilt or sleeping bag?
4. i haven't seen much on the top quilts compared to bottomquilts. do top quilts keep you as warm as a sleeping bag ?
thanks in advance
