This is a great choice for day hikes and short trips. I’ve been using for everything from hiking, bike riding or even to my children’s soccer practice. It's very lightweight and comfortable which makes it very easy to carry. The design is very cool. The hydration sleeve, multiple pockets, and mesh panels for extra storage pretty much cover anything you might need. There's a 'lid-lock' for securing helmets, which is a nice touch. Which I didn’t think I would need at first but the first time I went bike riding it was very handy to have a place to stow my bike helmet.In terms of comfort, this backpack does a great job. It carries loads well, with most of the weight directed toward your hips and lumbar. The breathable molded back panel and adjustable shoulder straps make it easy to get a good fit. I will say that the waist strap is a bit thicker than Id prefer but for hiking, having that support is nice to have.The size is versatile but falls between categories. It's a bit large for regular day trips and a bit small for overnight camping unless you're packing minimally. We don’t really go camping but I imagine if you pack light, it could work. As a weekend bag for more civilized excursions it will easily fit in an overhead bin and I personally like to keep it in the front seat of the car with me when my family makes the long road trip to grandmas. Because of the size and design it works well to hold electronics, snacks etc.Overall, Im very happy with this and could recommend this to anyone looking for a quality bag for road trips, hiking, camping, biking or just whenever life calls for a compact midsized bag.
