The Ultra-Sil™ Stuff Sack is an ultralight but durable solution using a 30D siliconized CORDURA® fabric. Ideal for organizing gear in your pack or bag, these stuff sacks incorporate a reinforced pull handle on the base, a durable pull tab at the top and are available in several great colors. The slippery exterior means they slide down into tight spaces easily.

FAQs

IS THE ULTRA-SIL STUFF SACK…?

• Waterproof? It is only water resistant. The seams are not tape sealed, and the top does not utilize a roll-top closure.

• A good choice for a (lightweight) tent storage bag? Yes. If you carry the poles separately (for instance, under the compression straps of your pack), you can pack the canopy in an Ultra-Sil Stuff Sack.

• Able to be printed on? No – the siliconized fabric cannot be printed on at all. Please contact us through our  if you need (larger quantities of) printed items.
