Cuben Fiber Pack Liner, Dry Bags and Coupon Code

Wow I've never seen black cuben before. That's looking sharp. Nice prices as well. Too bad I stocked up on the GraniteGear uber-expensive ones.

I have a black cuben fiber quilt, but it's not nearly that dark. I think that dark black looks pretty sweet. Nice stuff on the site too. I may have to place an unplanned order.

The black cuben is very "mysterious" looking haha. The color is dark because the material is a heavier version then most people are use to seeing. I built a few dry bags out of the CT1K.08 a while back and they haven't lasted as well as I would of liked. I never realized dry bags and stuff sacks were subjected to so much abrasion and puncture. I didn't want to offer a product that you had to "use at your own risk". So I built something that would be durable and leak free, yet be lighter in weight then Silnylon. These seem to be fit the bill quite nicely.

What sort of internal volumes do they have?

Got mine and they look great.
Thanks!

I saw those, but those are areas (length x width), and don't tell me how much they can fit, unless they're for map storage.

For example, Granite Gear CTF3 drysacks are described as 7 Liter: – 4.5" x 17" x 17".

The bags are actually 2" longer then stated to allow for rolling.

4×6 .5 Liter (camera and gps fits perfectly)
5×8 1 Liter
6×9 2 Liter
8×12 4 Liter
9×15 6 Liter

I filled them so you could roll them once with water then measured. I figure you can't more exact then that.

guesses size wise for a light (16 oz) down quilt? trying to reduce volume as much as possible

I would think the 8"x12" would work perfectly. I don't own a quilt since I am still "old school" and use a bag

The 4 liter should work for your quilt depending on the internal volume after the rolltop is closed. It will be a little tight, but should work.

Rolltop bags also work for compression sacks so if its a little bit big you can just roll it down and compress your items.

thanks- ordered a 8×12 (along w/ a 4×6, 5×8 and 6×9 :) )

haha thanks for your order!

Thanks for the BPL offer, Lawson. When I ordered my sacks, your site said the pack liner would ship in a week (back ordered). Do you see any possible delays beyond that?

Lawson:

Do you do custom orders? Thinking about a bigger liner to house 'everything' inside my Mountainsmith Ghost backpack — say 30" x 18" x 14". If so, can you please PM me about est. cost and weight? Thanks.

The only delay is the my lack of material. I already have more material on the way so once it arrives I will build them and have them ready to ship the following day.

My focus is standard items but I will do custom orders. I recently built Doug Ide a 4 season cuben tarp.

I actually plan to build another 2 packliner sizes. I was thinking a 60 liter and a 90 liter. Would those interest you Ben?

pm me when u got it

got mine today- they look great!

the 8×12 was a very tight fit for my quilt, but it did fit- exactly what I was looking for :)

thanks

dry bags are out of stock.

More material should be coming in today. If that happens then new stock will be available in the next day or so.

Thanks,
Lawson

We have more drybags and packliners in stock. The price will go up after the sale ends on June 15 so act fast.

Wanted to give my initial thoughts after receiving the 30L cuben pack liner.

Weight = 2 oz

Black cuben fiber, seemed quite sturdy to me. I don't have any other cuben items to compare it too but it was thicker than I expected.

Seams are taped and the construction looks very solid.

I was not sure if 30L would be large enough as my pack is larger. However, I think the size is just right. I can fit my sleeping bag, all my clothes, my homemade net tent and my ditty bag with all the little miscellaneous items with some room to spare.

I cannot fit my tarp, cooking gear or food bag but I am not really worried about keeping these dry.

I filled the bag with air, closed the top and squeezed, air did leak out very slowly. I think that it would not keep things dry if completely submerged for very long but for rain or an accidental fall into a river I think it will perform well.

My overall impression is positive and I look forward to some good wet weather to try it out.

Hey Adam,

Thanks for your feedback!

I assure that these packliners and dry bags are water-tight. Please fill it with some clothes and submerge it for a while. If your drybag leaks water please return it since these drybags are designed to be 100% water tight.

Dry bags in generally are not designed to be 100% air tight since a water molecule is thousands of times bigger then an air molecule. It's the reason breathable laminates like Gore-Tex and eVent work.

Lawson, do you expect to have the pack liners in any color other than black at the reduced price?
