Review on TRIWONDER Hydration Pack Backpack 5L: Ultimate Performance for Marathon Running, Cycling, and More! by Russell Roberson

This is a great hydration pack at an affordable price. Good materials for the price, light and comfortable and the multiple pockets are great. Seems to have better stitching than other backpacks I've looked at in this price range. The zippers are also of good quality. I especially like the flexible opening pocket on the back. I can carry, grab and get things in it without taking off my backpack. A bit lengthy, but doable. It's also very adjustable. It's also large enough to hold a full 3 liter water bladder. I'm 5, 11 and 250 pounds and still have 6-8 inches of room in the adjustment straps when adjusted comfortably for me. On the other hand my teenage daughter wears a size 4 Petite and we were able to easily adjust it to fit her. Again, there is still room to get smaller. The front cross straps slide up and down so you can easily move them where you want and they just stay in place as you run. Because it has a higher water reservoir than my old pack, it feels lighter and more balanced when running. The only thing I can say against the product is that the collapsible water bottle doesn't fit well in the pocket provided. He enters, but with a lot of work, and there's no turning back when you're on the run. However, standard single-use water bottles are easy to put in and take out, and I have a refillable bottle that's the same diameter, so I have to carry electrolytes around. I'm not taking any stars off for the water bottle because I didn't buy it for it, but even if I included that in the rating it would still be a high overall score of 4 plus.
