"This is a -20 C synthetic (with 3M's liteloft insulation) sleeping
bag. As you would expect from a synthetic with that rating it's
quite bulky. It's also hard to pack into it's stuffsack (maybe it's
because I have the long model?). But it kept me nice and warm in
~ -20 C with a lousy tent (lot's of condensation). And at ~
CAN$180 it's the perfect poor student's winter bag!"
