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.
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.
The bag itself is perfect! Super bright color, love the multiple pockets for different ease of accessibility. Where I messed up was not realizing that even though I'm plus sized, a plus sized pack was not the right choice. The straps are too long for my short torso and set widely apart. Very light and I would imagine comfortable for wider shoulders. I am 5'1" and 190 for comparison.
I bought this pack as an alternative to a Zulu 30 that I regularly use, because I wanted a smaller pack for times when I'm not the family pack horse, and to be sure it would fit as an airline carry-on. The pack carried well, even pretty well stuffed with a fleece, rain gear, miscellaneous personal stuff, and lunch. There's no raincover, but it seems to be fairly waterproof (I wouldn't trust it unaided in a major storm or full immersion... but did well in lighter rain and on a sea kayak without a cover). I was disappointed that the side pockets don't fit a 1 L Nalgene bottle...
I purchased this as alternative to a 35 L Gregory Zulu (too big for some purposes... but if you're the packhorse for the family...) daypack. No included raincover, but it's reasonably waterproof based on a wet week in Acadia National Park, and you can add one. Over all, a good size for day trips with basic gear (jacket, rain gear, lunch). I found it carried well for me, and I didn't really use the waist belt, which does stow nicely into the pockets provided. I was disappointed that the water bottle pockets on the side don't fit a normal 1 L Nalgene bottle.
I really loved this backpack over several other brands I tried but unfortunately the lower portion of the back dug into my lower back. A few hours after wearing it on a test "hike" in me neighborhood, I felt a soreness in my lower back, almost like a bruise, that lingered for a day. When I put the bag back on I realized the soreness was exactly where the bag was pressing against my back. I fall within the measurements for this bag, but something about it just doesn't fit me right which is super disappointing because this bag is awesome. Things I loved about this bag that sets it apart from other bags in this price range: - clip on the external pocket keeps things secure - shoulder straps are cushiony - zippers have a satisfying grab and open and close easily - grab handle at the top of the bag is thick making it comfortable to hold the bag from the handle - bag holds A LOT without feeling like a large bag - it's really light but doesn't feel cheap or flimsy
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.
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.
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.
Awesome versatile pack! It is sturdy and stylish. I love all the pockets and the straps keep it secure to your body.
