Normally I don't write reviews, but Tripole offered 5% Cashback to write a review on their website, even though we bought this on Amazon. My 5 star rating is not dependent on getting the deal. We want to be helpful to potential buyers.
When the pack arrived, we were anxious about quality of material, zippers, closures, and functionality. On examining the bag, the first thing that came to mind was to use it on our long Bullet (Royal Enfield) trips. It is made out of very sturdy nylon, and the zippers look rugged. It has a LOT of room, while still being light. When you strap it on your back, the padding is very comfortable and adequate. We will use it on our tour to Israel this year, as we can unzip the smaller backpack and carry it around as a daybag. The rest can go under the bus from place to place on a 14 day tour. If you are looking for a higher capacity ability to camp, hike, or travel, and carry a lot more gear with a lighter weight, then go for it!
