Blast--Hiker..others..
i always buy sleeping bags in "long"--i may not need the
length but i found you can really pull it up over your
shoulders better than the "normal" size..
here's a canoe buddy of mine..he is into all the
expensive light weight--top of the line gear

thats a $325 Wallcreeper..if the arm holes had sleeves
i could see paying that price but you have to wear a
polyfluff top to keep your arms warm
