Stylish and functional.
Color: Green, Color: Green
First, I love the color. Earth tones are my go to. This is a nice shade of olive green. The design is stylish. Minimalistic is also my preference. It’s very much form and function. So I’ve mostly used this hiking. It’s big enough to store everything I needed for longer or overnight trips. I had a light jacket, sunscreen, flashlight, bug spray, several bags of snacks, a book, wipes and a water bottle. I could have packed more honestly. It’s waterproof and the material doesn’t snag or scratch. I’ve also used it for travel, mostly for my art supplies. It’s sturdy so my sketch book doesn’t bend. Theres a dozen different pockets and compartments, so everything can be separated from each other. The size is good, the strap lengths are long and easily adjustable. The only downside is the compartment for a water bottle or travel mug is pretty tight. Other than that I like it a lot.

Good solid backpack
Color: Latte Beige, Color: Latte Beige
I’m really happy with this backpack. It fits my Lenovo Legion 5 16'' perfectly with just a little room to spare, but not so much that the laptop shifts around. The material feels sturdy and durable, and the waterproof design gives me peace of mind when I’m out and about. The travel strap on the back is a huge plus for me—it makes traveling so much more comfortable. There’s also plenty of space for my things, and I can easily use it as a weekend bag for 1–2 days without it feeling bulky. The price is not bad, for the quality you receiving is honestly really good. If you’re looking for a reliable, well‑made backpack with lots of room, this one is a great choice.

A really nice one!
Color: Latte Beige
This was so close to perfect for me! Love the fabric, the structure and the setup. I just didn't love the really thick padded laptop pocket. It made the bag bulky than necessary and I don't usually carry a laptop.
