The ULTRA-SIL duffel bag is a lightweight performer perfect as a carry-on or carrying around the city. A 40-litre volume capacity means storing essentials and then some. The Ultra-Sil fabric emphasises packability, durability and strength. The full top zipper means easy access to the main compartment. It packs into the stuff sack and has a Hypalon key ring attachment. Toughness comes from reinforced stitching at key points and the bar tack. The whole bag weighs only 80 grams.
