Zpacks.com Cuben Fiber Stuff Sacks

Summer UL gear List – 9.93 Pounds

Upgrading your stuff sacks to ultralight cuben fiber stuff sacks is often overlooked as a way to reduce your pack weight, but it can have a huge impact if you use heavier waterproof stuff sacks or compression sacks today.

I switched to cuben fiber stuff sacks this spring because a lot of my older silnylon stuff sacks had bitten the dust. I upgraded to the cuben fiber stuff sacks made by Zpacks.com because they’re super lightweight, and they come in lots of different sizes and colors which helps me keep my gear organized, and Zpack’s prices are very competitive for cuben fiber gear.

How much lighter are Zpack’s stuff sacks? They’re often 50%-75% lighter weight by volume for a comparable silnylon stuff sack with a roll top closure like the Sea-to-Summit Ultra-Sil Nano, and even more if you use compression sacks.

For example, here are the weights of the bags I purchased and the gear that I store in them:

1. Large, (Rectangular shape) with 12.3 liters of capacity - weight: .4 oz.  /  11 grams

Used to store my sleeping quilt or  down sleeping bag

2. Medium, with 5.6 liters of capacity - weight: .3 oz.  /  8.5 grams

Used to store extra socks, fleece sleeping hat, long underwear top of bottom

3. Slim, with 4.0 liter of capacity - weight: .2 oz.  /  5.7 grams

Used to store shelter

4, Small-Plus, with 3.3 liters of capacity - weight: .2 oz.  /  5.7 grams

Used to store my  first aid and gear repair kits

5. Mini, with 0.9 liters of capacity - weight: .13 oz. / 3.5 grams

Used to store personal items

When you have to measure gear weights  in grams, you know it’s ultralight!
