I just noticed this (maybe?) bargain, too–at the REI Outlet. $165 for a long and, of course, free shipping if sent to the nearest store.
I have a grandson who will turn 10 next spring. He's now mature enough for a down bag. The alternative would be to get his younger brother (5) a TNF Tigger, which would be the third "Tigger" in the family. The problem is, of course, that the 10-year-old will outgrow his Tigger in a couple of years. That's why I thought that a mid-range down bag would be better for the older boy–lighter, more compact and, hopefully, will last him at least through his high-school years. If, as a teen, he decides he no longer wants to backpack, it's less money down the drain, too.
Another possibility would be a Campmor 20* (supposedly) down bag, which is heavier than the Sub Kilo. It of course has lower-quality down (550 weight, I believe).
For those of you who have found the Sub-Kilo to be more like a 30-35*F bag, have you been able to take it to nearer 25*F by wearing more clothing inside?
Any suggestions are most welcome! Money is as much an issue as weight here! Maybe more!
