...if the prices keep coming down. My unit tested various cold weather uniforms and sleeping bags in northern Norway during the 1980s. I've spent plenty of time freezing in the old military "mountain" and "arctic" bags.
When the modular sleep system was first issued it did not come with the goretex bivy cover. We used ponchos or canvas shelter halves to keep the moisture off. The bivy defintely completes the package now. For the most bitter colnditions it helps to have polypropylene thermal underwear, down sleeping booties, and wool cap. (If you chill easily like I do you can drag a military poncho liner into the bag as well for another 10 deg. of protection).
Your excitement with your new purchase is entirely justified because that's how I felt the first time I used one. Enjoy!
