Great Pack
Bought this for me and my girlfriend for our treks through Big Bend. They are, as has been my experience with anything SOG, awesome. Although they are bulky, the water packs didnt add much of any weight that we needed to try rebalancing as the the pack sits right at your back. One drawback, if you cou d call it that, is the water in the hose got a little hot, but thats to be expected in desert hiking.There are more than enough pockets tucked into this pack to carry just about anything you can fit in them. In this case, lots of snacks for the hours we spent on the trails.With the mole system set-up, I also have a first aid kit strapped to mine. Even then, the weight balanced evenly, didn’t feel like I was being dragged down. The waist strap also held the pack in place.One thing to note, if you carry hiking sticks like we do, there isn’t anywhere to put them thats out of the way when not in use. I am buying d-rings to attach to the pack for that purpose.All in all, it’s a good pack for the money.

Honest review. Works well.
Great backpack. Bought it a while ago for snowboarding and dirtbiking. I like how slim it is when not fully packed. That was my biggest worry when it came to it. Perfect small compact size. The bladder is good but when filled to the top it makes a weird buldge on your back. Works well for my uses. Plenty of room and pockets. Keeps dry in the snow. Seems pretty durable. My only issue with it is the bladder where the hose connects to the bag, its just some soft plastic so super easy to cross thread or mess up when putting back together. Could Potential leak point. The mouth piece i have NOT had leak on me like other people are saying, as long as you close the valve. Would buy again, would gift.

Not a huge bag with a ton of space… however worth the price it you are wanting to stay light
I bought this for a get home/ emergency bag to leave in my vehicle. Pending on your needs and or situation this bad may not be for everyone. I’m using it for the hydration pack, storage of a first aid kit(which is a large flambeau 5003). You can fit 2 trays in bit it makes the bag very tight. Middle storage is decently sized. The front 2 pouches are not very big, however if you are packing light than they could be used for snack storage, lights, matches, etc. Plenty of molle web to attach to as well. In conclusion I seems to be a good just in case/ hiking and cycling bag. Worth the money

Great pack for the money!
I got this for a biking/hiking trip in the mountains. It held up the whole time. Great water storage for the water pack. It has plenty of room and lots of different compartments. Great pack for the money.

Great lite duty bag
Bought it for a nursing work bag and it fills that role fine for my needs. I wanted a smaller thinner two strapped backpack over the sling I previously used. It is wide enough to hold a folder with my paper documents in it and thin enough it doesn’t take up much room. It does open and expand to hold a weekends worth of items and works great as a carry on bag. The quality is on par for the SOG bags I have had. Some stitching isn’t straight the molle is crooked and there is some loose threads but it isn’t falling apart and should last. My last con would be the lack of side molle for attaching a water bottle holder.

Perfect size
I have not used it yet however I wanted to write a review before I forget to. I was worried I wouldn’t be able to fit the items I wanted in this bag but it is the perfect size! I was able to fit a sleep pad, 1person tent, cooking supplies and food. Still gathering supplies and have no doubt it’ll all fit. I may need to attach my sleeping bag to the bottom but there is plenty of room and it is well made. Can’t go wrong with sog.

Excellent product from SOG, not to big or too small. Great straps, buckles, zippers, and compartment sizes. Easy to use/clean hydration system “BIG MOUTH” opening for pouring liquids, drinking tube has it’s own insulation sheath and mouthpiece has on/off valve. Great value for the price, also has mole and velcro attachment points. Well thought out and designed, makes my “Camelbak” mule obsolete and overpriced. Ty SOG.

Compre esta mochila para el uso diario y la verdad es que estoy muy complacido con ella.La bolsa principal te da la posibilidad de abrirla completa tiene organizadores dentro de las bolsas, los detalles como las jaladeras de los cierres el logo en la parte trasera y el emblema en el tirante la hacen distinguir por sobre las demás.Los materiales son medianamente buenos pero por el precio la verdad es que están bastante bien

I use it mainly for mountain biking and it fits the bill. Well made with enough space to bring tools and your lunch for long rides. Actually comes with a 3 liter water bladder! Maybe not the most breathable for your back but overall it’s great for the price.
