User Review: JanSport Men's Orb Jacket
Fabric: some kind of nylon, a ripstop version
Fill: 650 fill down, or maybe 550
Price Paid: gift
I have used this on Rainier, Devils Peak, Devils Thumb, Eldorado, and countless other peaks. Bottom line, it works great. It's lightweight, packs super small, and it's very warm. My only complaint is that there's no hood, but for a jacket this inexpensive, but this well made, it's worth it. Just carry a few extra hats.
