Great for travel or day hikes!

I've used it once or twice and have initial impressions

So, I can’t say I’ve put this through the ringer because sadly it was stolen in Europe (completely my fault, I sat it down out of my sight line). But for the first part of my travels it was perfect for walks, metro rides, and shopping. Also great for a day hike (can fit water bottle, camera, and extra layer). Will like purchase another one.

Too Small

This is too small for what it is advertised. there is no way this pack can hold 18L. a case of bottled water is 30 - .5 liters which would be 15 liters of water. There is no way this pack could even hold the case of water if you poured it in.

Atom (really) means Small

I've used it once or twice and have initial impressions

Good pack. Solid construction. Functional and comfortable. Downside is this bad boy is small and I have 'things' I like to carry.

Do you think this would hold a small laptop computer?

For sure Katie. It held my 13in Mac without an issue. I just needed a touch more space than what was left over.

Simply Good

I've put it through the wringer

Great daypack. Simple no frills and bombproof. I've carried it for 80 miles and it looks like its fresh off the rack. 18L is plenty big for Socal hiking and everyday use.

Does it have an area to a hold a bladder? It doesn’t appear so, but I just wanted to double check since you’ve used it for outdoor activity.


How is this for day hiking? The back zip pouch seems like it would fit a hydration bag fine, which is usually less annoying than a water bottle on the side anyway.
