Great features

21 days ago
Very, very good for everything. Comfortable to carry, not too warm because of the design. It takes rain trousers, rain jacket and a warmer long sleeve pullover at the same time, so good capacity.

Get this Backpack!!!!

a month ago
Love this backpack!! I brought it with me on a 4 month trip in Asia, and it was the perfect smaller backpack to have. I brought it on shorter 3-4 day excursions leaving my main pack behind, and it was the perfect size to fit clothes, toiletries, a small towel, everything you need. I love the front pockets along the straps as well, It's a perfect spot for your phone for easy storage and grabbing. It also fits very comfortably on the body, and lastly I got major use from the straps on the back of the pack, I would stuff my jacket or shoes in there which made packing all of my stuff a lot easier.

Be Ready For Piling Caused By Back Material

5 months ago
Great backpack but the only downfall is the material on the back will cause your clothes to pile. Used my Aerios 18 along with my Cormac tee (first time using it as well!) for a quick hike and it immediately caused piling. Really disappointing. A 70 USD backpack and a 180 USD backpack should have better quality and durability than this. Hope Arcteryx helps me out!

Awesome school backpack!

5 months ago
LOVE using for school! I use the Aerios 18 for my school backpack. It perfectly fits my computer (macbook air 13) , ipad air, notebook, a book, my 18oz hydroflask, and keys. I like the strap mesh pockets, perfect for straggler hairties, keys, or chapstick. One small thing, if the pack gets too bottom heavy (ipad, heavy calculator), the frame of the back will curve a bit. I usually have no problem because I have my laptop to even out the weight but on those days I don't it looks a bit wonky!

Best for day speedy day hikes/ scrambles

7 months ago
If I know I’m going after a straightforward hike/ summit/ scramble objective (no glacier traverse) and I know I’ll have water sources along the way, this is the pack I reach the most. It’s super light. The vest fits incredibly comfortably. The position of the two front water bottles makes it possible to sip from them without taking them out. And the compartment of the bag is spacious while being relatively water resistant. Because this pack is so super light, I’ll even pack it in my heavy overnighter bag when I know we’ll be leaving all our overnight gear behind for us to push up to a summit. I currently have no cons for this pack. It’s perfect for my needs. Highly recommend having this pack as part of your go to kit for day hikes and easy scramble objectives.

The ultralight, ultra-strong grid pack fabric sheds light rain and stands up to all the drops, drags, and snags a pack encounters on the trail.
