.5 oz cuben stuff sack? on 10/17/2013 16:07:52 MDT Print View

i have a friend who offered to make me a 35L dry sack out of his .5 oz cuben, pretty awesome, but due to its application i dont know if it will be strong enough. thats where you guys come in...

the application: i am redesigning my REI flash 45 backpack to cradle a dry bag in the main compartment area. I've cut away most of the main compartment so the pack just has a back panel, bottom, and front panel, with the stretchy mesh coming up a few inches on the sides, and compression straps to keep the front and back panels attached. my idea behind this concept is that it enables me to use different sized dry bags depending on size load im carrying.

will a .5 oz cuben stuff sack carry up to 20 lbs of gear in it without bursting?

I have a 0.51 oz cuben stuffsack that I use for small stuff and toiletries. After 2 years of use it is covered in tape from stuff poking holes in it and from the stitched seams starting to pull open. A 1 oz cuben drybag that I bought at the same time has no holes and is still waterproof. I would recommend using at least 0.7 cuben and probably the 1 oz if you want it to actually be waterproof.

That confirms it. I will just buy a 35l s2s dry bag instead.

I like the concept! on 10/17/2013 19:22:23 MDT Print View

Well, it may not work with the extra-thin cuben (for the reasons above), but I really like your concept of adding whatever size bag you need within a lightweight frame...

I will probably carry the 35 most the time. But can surely bump it up to a 50 if I need it. One pack to rule them all!

That's smart dude. What's the stripped down pack weigh?

not sure yet, i will post a complete write up on it when i am finished. so far ive stripped off about 5-6 ounces from a 34 ounce pack, but there is still a good bit to go. im shooting for 24 ounces
