User Review: MontBell Men's U.L. Thermawrap Jacket
Fabric: 15-denier Ballistic Airlight calendered nylon shell & lining
Fill: Exceloft synthetic insulation
Price Paid: $90
I definitely don't leave home without this jacket in the winter. No it doesn't get that cold in the Valley of the Sun, but up in the northern part of Arizona it gets wet, windy and snowy too.
This compresses down to almost nothing so I can store it anywhere. I almost wish I lived further North so I could justify buying the UL Down version!
