Great little bag with features to expand upond.

I've had this for 4-5 years now in black and canary yellow. I bought to replace my Marmot Kompressor. I added a magnetic clip for the water bladder and some 1/8" reflective shock cord through all the loops around the bag if you haven't notice. I also added a helmet mesh carrier. This backpack doesn't come with one. That being said, let me tell you what I put in this backpack: For an overnight or 2 days in the backcountry, I can put a sleepingpag, a 2p UL tent (supermega ul2 or ghost us2), sleeping bag, liner, bug spray, sun screen, chap stick, footprint, poles, small medical kit, water bladder, filter filter, battery charger phone charger, phone, inreach mini, two headlamps, something to sleep in, my rain pants and shell, ice axe and microspike as well as bear bag kit and food. I enjoy long pushes and scramble missions like the full Tattoosh Range Traverse Eastbound and down light and fast! Last week I surprised people on the trail when I was pulling out almost a double rack, 4 lockers, 4 non lockers, single double and triple length sling, cordalette, microspikes, ice axe, phone charger and batter changer, 3L water bladder full of caffeine and electrolytes, sunscreen, bug spray, crack gloves, rappel kit incuding gloves, and a 60m dry rope and my helmet atop it all and it was ALL in the bag with my climbing shoes and harness and ATC! I probably had some other nicnacks but it was what it was! How did I do it? Well, notice that long strap along the bag... you can move it from the bottom and girth hitch it to the top loop expanding the space with the bag. If I needed to carry overnight gear and real crampons I would just load it up, put the rope on tope, cinch it all down, and then used my shock cord to help secure it all around and the helmet in the accessory mesh carrier I bought (arcteryx) and then crampons outside the bag secured with shockcord through the extra loops. It's phenomenal. I don't usually hike with a stove and I eat all quick grab good like gummies and protein cookies and bars. It's just a day or so right? C'mon!

Very lite weight

Great pack I’ve had it for a year now and the drawl string clip broke. It still works with a small slip knot. Other than that it’s a great lite day pack.

Great pack to bring along for travels!

I bought this pack to bring along with me during travels, to carry as I explore cities, or for nature day hikes. It is very light, yet large to hold shopping items, extra coat, rain gear, water, snacks. And it packs away into its own small pocket to throw in my luggage. It's perfect for what I need.

Great travel pack

Perfect travel pack - I’m an airline pilot and it has served me well all over the country- I recently used it for a multiple day trip to Mexico City. Pyramids, balloon rides, museums - it was perfect

Great small pack. Fits 13 Inch MacBook

Love this little pack! It’s small but carries everything you’d need for a quick run out in the city or a short day hike. I do wish that it had some rigidity but that’s because I use it often enough that rolling it into itself isn’t how I’ll be using it. Fits a 13 inch Mac Pro in the pocket I believe is designed for a water pack. I like the open and close mechanism. Great little pack.

Needs design work but well made

Love how light this backpack is and it’s comfy to wear with quite a bit of weight in it. Downside - front zipper pocket is too small and the outside open pocket is not designed to hold a water bottle as it’s too short and too wide. bottomline it’s a bit too minimalist. the larger version has three outside zipper pockets which is designed much better.

Great daypack!

Love this daypack. Easy to use and very durable. I'm giving this a 4.5/5 stars because I wish there was a waist strap to alleviate some of the weight I carry from my back, but the chest strap helps. I also wish there was padding on the back side for more comfort.
