Less smell, more waterproof = good idea. Sorry bears.

Masked the smell of spices in my bag

Was doing a winter trip where I carried 5 days of food last week. I had one gallon bag per one day’s worth of food. I had a total of 5 one gallon bags that weighed about two pounds each and the NyloPro bag was able to hold that amount of food. It also masked the smell of the pungent spices that I had in the bag! Would recommend!

Zpack Walking the Camino

The front pack was wonderful! While walking everyday, I had everything I needed right in front of me at all times! I did think this was waterproof but in a heavy side rain & wind - my passport and other items were damp! I totally recommend this!

We used these bags as backpack liners in the Zpack backpacks to keep our gear dry and in the Zpack bear bag to keep our food odor-proof. Although there was no rain to test the bags, I’m sure they would have kept the heat dry. They are much lighter and easier to use than trash compactor bags that so many hikers use. We saw one bear in the area but our food remained safe. I must say they are extremely lightweight, easy to use, fit both bags perfectly (I cut the length of one bag for the bear bag but the width was exactly right). I will continue to use these bags and highly recommend them.

They seem like a good bag. And very fast service from Zpacks.
