Very Good, Simple Bag

This is a very good, very simple bag. It has a small outside pocket on the top and main compartment. I have used it for a few hikes and a few 20+ mile runs with a bladder inside (it does have a loop to keep the bladder upright). Good bag for the money.

Great Day Pack For Experienced Hikers

It's a great pack for a day trip. Though some of my hikes are long days, this can carry the essentials I need but is light and versatile. Two water bottle pouches on the outside are great. Can be combined with a Fanny pack or other items.

Good Day Pack

I've used this for mountain runs and sport climbing. It took me a while to discover the hose pass-through for the hydration bladder. The pack is mostly one giant space which has plusses and minuses. I wish it had another zippered pouch on the outside for snacks. I've kept them in the outer stretch pockets which works well enough I guess.

Good Quick Trip Minimalist Pack

Good smaller pack for quick fast and light trips with minimal gear, wish the hip belt had just a little bit of padding , i probably should have bought the plus version as i'm 6'3'' and 208 lbs athletic build and the regular pack is tight on me even with the straps at max.

Lightweight Daypack Perfect For Climbing

I use it as a climbing gym bag. Just enough space for a harness and chalk pot in the main compartment. Small items like keys wallet and vape in the top compartment. The dual tumbler holders on the sides are expandable and can hold a camelbak 32oz chute mag bottle with ease. The material is thin and light yet feels durable enough to be thrashed around. It can flatten just enough to be squeezed into a folded-up crash pad with no problems. Only knock is the waist strap could use some padding otherwise it's an awesome just-right sized pack
