This pack worked perfectly for hiking in Hawaii. We used it for several days for a total of about 50 miles and was perfect. Very good price compared to some other name brands. Good quality.
I ordered two sets of these (four total), I kept one red and one blue and gave the other two as a gift. They are a great size for kids. The only issue is the bladders and tubing for the two are totally different. One has a screw off top that comes off completely and is larger, the other one stays attached. One has a mouthpiece like a Camelbak where you bite down to drink, the other has an on/off switch that is a little stubborn and a clear cap that was lost in the first 5 minutes of use (where are you supposed to put a tiny clear cap on a hike?). One comes apart completely for cleaning, the other doesn't so it's tough to get the tube dry inside. All and all, they are a good deal for the price, time will tell how the insides hold up.
