Great daypack

Great day pack for hiking. The pack is so light and comfortable that I barely feel it even after hiking most of the day. I like how easily accessible the pockets are on top. It’s also the perfect size for my lunch bag, emergency kit, jacket, and first aid kit.

Awesome bag, bad fit

I was in the market for a new backpack for hikes, biking to the library, and walking around the city. Everything about the bag was perfect, but it was WAY to long for my torso. I should've done a better job researching what best fits my torso. oops! My previous pack was 16.5in long which fit me perfectly. This pack is 20in long. The pack I decided to keep is 16.93; fits well! Sad the Nano didn't work out. Also, I bought the "Burnt Amber"; looks a bit different in person. Added photos; hope it makes the color more apparent. If bag fit be better it would've been 5 stars.

Love this very light backpack.

I have issues with both my neck and shoulders and was looking for a way to carry a pack without neck and shoulder stress. I found it!! I can position the collar strap on this pack to bear the weight thus giving my neck and shoulders a break.

Great pack for day hiking

This pack checks almost every box for what I want in a day pack. The Nano 20 is lightweight, holds a 3L hydration bladder in a dedicated area and carries all my needed stuff very comfortably. My only gripe is the stretch side pockets. They are almost large enough for a standard 1L nalgene, but not quite. I feel like this could be achieved with very little weight penalty or design change. I primarily use a platy 3L bladder but it's nice to have options and sometimes I prefer to carry nalgene bottles. Overall, this pack is very comfortable and has done great on my first few hikes.

12 Miles a day - Perfect Pack

Hiking 12 miles a day in the lake District of England. A perfect pack for 2L of water, water bottle, rain gear and a thermal base. Not too big or two small. Love the 4 separate pockets on a small bag + the venting. Great bag.

Nice day pack

I purchased a Nano 20 as an alternative for shorter trips, or where I wanted to carry less gear than my Zulu 35 (family pack horse duties), and to be confident it would be okay for airline carry-on. Overall, very happy with the pack. My 3L 3D Bladder fit nicely, and the pack carried well, even crammed with 3 liters in the reservoir and another spare 1 L of water, rain gear, a fleece, and big lunch on multiple hikes around Acadia National Park. The pockets to stow the hip belt worked nicely. I was a little disappointed that my Nalgene wouldn't fit into the side pockets.

Small, useful, and not bulky

It's small, functional, and sleek. Very utilitarian.

Nano 20

This is a great little back pack. It’s light and fits great. It holds enough for a day hike or any day adventure. This has been great for me because it keeps me from packing too much but allows me to pack what I need. I have used this for skiing, traveling and for work. The only downside is side is the small loop used for hydration hold the hose in place on the shoulder strap broke about 2 months after every day use. I was not even using it with a hydration pack/hose. Still I would recommend this pack.
