Looking for a cheap underquilt just to get me started. And by cheap I mean, around $50 or less. Snugpaks are unfortunately too heavy to hike with, so I'm looking for something more along the lines of the Yukon Outfitters Kindle or the OneTigris underquilt. Just something to keep me warm and last a year or two while I save up for a nice down quilt. Surely someone has purchased one and later upgraded?
