I am very happy with my new Nathan Trail Mix 4 Water Belt for Running! I needed a belt that would let me carry more than a half liter of water for the longer runs I had started doing this summer. Other systems I tried didn’t work because they bounced too much when the weight of the water got too high.
Nathan’s solved that problem by designing their water belt with an elastic material that stretches to give a secure fit to the body, and by distributing the water to four, well-designed water bottles and their fitted holsters. The belt is adjustable, and I found that I had to adjust it tighter than I initially, because the elastic waist band stretched more than I thought it would.
A writer of one of the reviews I read suggested that it be worn up by one’s natural waist rather than closer to the hips. I generally think that idea is a good one, though I discovered that when I tried to wear it that high, it slipped downward a little bit from my waist over the course of a run. Nonetheless, it remained comfortable. If it didn’t remain comfortable, I could always tighten the belt a little tighter so it would be less likely to slip.
I tried wearing the belt with the buckle forward, which is what I would consider the normal way to wear such a device. I discovered that the front two water bottles are not spaced very far apart, and it felt uncomfortable the way the water bottles hit my body both above and below the belt. Fortunately, you don’t have to wear it the “normal” way. I tried it with the buckle at the back and the storage compartment in the front, which worked just fine. But in the end, I preferred to wear it side-ways, with the storage compartment on the side (my right side, since I’m right-handed).
