Functional and comfortable

7 days ago

I’ve been on the lookout for a daypack that’s light and comfortable without losing functionality. This fits the bill. I think what makes it so unique is the shoulder straps and the way they spread out wide over your shoulders to spread out the weight of the bag and then the twos chest straps come across to secure makes it feel unified with your body. Incredible design. Couldn’t recommend it enough.

Get this Backpack!!!!

1 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.

Awesome school backpack!

6 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!

Versatile lightweight daypack

7 days ago

I picked this up from REI for a lightweight/less technical day hike pack - had 3 days planned in Mt. Ranier (summer - so didn't need the capacity for extra layers). The running vest shoulder straps paired with some external pockets and lash straps was everything I needed externally; I never got close to filling it all the way up. I didn't experience the loosening of the sternum straps (Arc'teryx-specific design/construction) like some have complained about (in fact I quite like them), but wasn't thrilled with how low-cut and angled the side pockets were. Taller water bottles didn't feel fully secured (even when tightened), so I added some packmod bungees on both sides. Would I have liked that in the original design? Sure. But despite it all it's now my go-to day hiking pack. Sizing info: I'm 6'2" 185lbs and the fit is great. Even has small load adjuster straps!

Love the pockets!

1 week ago

The size is perfect for a day hike. I love the hole for the water bladder and that the backpack has pockets in the front for snacks or your phone so that you have quick access and you don't need to take your backpack off completely. Super comfortable and I like the colour!

Great features

1 month 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.
