Note that since this post, these pack liners have become a permanent part of the Zpacks site. Check them out Here!
I am happy with my (1.2 oz) ZPacks cuben fiber pack cover and have no plans to abandon it, but past experiences have proven that a pack cover will not keep the inside of a pack dry on its own. And now that I have started carrying more down items I figured it would be wise for me to pick up a waterproof pack liner. But after thinking about it, I decided I didn’t just want a pack liner that I would be swapping out every so often. Instead, I wanted to look for a fully waterproof dry sack that would function as a pack liner. So, I began looking for one that would fit inside my ULA Circuit as best as possible.
Thanks to one of Wallace Hunter’s AT videos I came upon the Outdoor Research UL Dry Pack Liners which sounded great and looked like it would fit great in the ULA Circuit, although I didn’t like the sound of the added weight. I then came across Lawson Kline’s cuben fiber dry sack and this one was exactly what I was looking for! Very light-weight and clear so I could see through it. However, I waited just a little too long, and now he is busy working on his tarp line-up so he is not currently making any more of his dry sacks. So, I kept looking…
I looked at the Mountain Laurel Designs large size dry sack bag, but it was just a tad smaller than I wanted. I was stuck on the size 18×36 and this one measured 17×35. (Yeah, I was being nit-picky here.) But at the moment, this one was leading the pack since Lawson’s were out-of-the-question for the time being. And the price was pretty nice on this one too, $37.
Now, of course I also checked at ZPacks, but there was nothing listed on the site that was even a dry sack, let alone big enough for what I wanted. So, I figured what the heck and emailed Joe. He quickly returned my email and told me it would be no problem to make a dry sack to my specs. He even included some estimated overall weights using various weights of cuben fiber. So, I picked the weight I wanted, added it to the custom button and submitted it. About a week later it was in my mail box…
So, in case you missed it in the video, here are the specs on this dry sack:
~Measured Size Laying Flat: 18×36 inches
~Measured Weight: 1.7 oz before seam sealing, 1.8 oz after seam sealing
~Capacity: approximately 2400 cubic inches or 39 liters (based on fit inside ULA Circuit)
~Material: 1.26 oz/sqyd Black Cuben Fiber
If you can’t tell from the video, I am very happy with this dry sack pack liner. It fits inside my ULA Circuit perfectly, it is very light-weight and being that it is made from cuben, it should be very durable (much more so than a trash compactor bag or some of the cheap pack liners). And of course, Joe has done a superb job, both on constructing as well as designing this dry sack. The hook-and-loop fastener that runs across the top not only makes it easy to close the top of the pack, but it also keeps the top stiff making it easier to roll closed. And of course, the highly waterproof cuben fiber should do a great job at keeping my gear dry!
So, thanks for taking the time to read this post as well as watch the video. If you have any questions just drop them at the bottom of the page and I will get back to you!
