Does not live up to my expectations

I purchased this bag for the foldable feature and waterproof capabilities. I’m on my first big trip with the bag. . The biggest issue is my hiking poles are not tight to the bag, so they slip and flop around. I’ve had to use a second cord to get them a bit tighter. Second the zipper on the front pocket is short creating a smaller opening than I would like. Many bags have crossed stretch bands on the front of the bag to hold things. This bag does not have that feature limiting the storage to inside the bag. It is nice to have a firm back of the bag against my back. So far I’m not thrilled with the functionality of the bag.

Sleek lightweight comfortable pack

Love the aesthetic of the bag. Lightweight and comfortable back panel. The zippers can be confusing at first but you get used to it. Haven’t been able to really pack it out and put it to work but on my short trip to the beach and pickle ball it worked great. Also extremely packable both folded and unfolded. Price point might be high for some but it’s a quality pack that justifies the financial investment.

Ideal small pack

Carried this for two weeks of travel in Greece - urban days, hiking, beach and boat days, air travel carryon. It's great, just the right balance of functionality and small size, packability, weight. It's now my goto travel and day hike pack.
