FuelBelt Helium 4 Bottle Belt Buy Now

I tried the Fuel Belt, Nathan Belt, and Amphipod in a store before choosing the Amphipod belt.

The Nathan Belt had the most comfortable elastic band, and the bottles were easy to remove and place onto the belt. However, I didn't like the placement of the bottles as the front bottles interferred with my arm swing (on the 4-bottle belt). Even if you remove the front two bottles, the cup holster still got in my way. With the 2-bottle belt, it rode comfortably on my backside, but I couldn't reach the pouch to grab jelly bellies and goo on the run. With the bottles in front, I ran into the problem of my arms swinging into the bottles again.

The Fuel Belt was comfy, but not as comfy as the Nathan. Had the same problem as the Nathan in terms of arms hitting the bottles and not being able to access the pouch when it's situated on my back. Additional disadvantage of the Fuel Belt is that it takes two hands to place the bottles back in the holster. Also, I seem to fall between sizes where the small was too small and the medium too large.

I ended up purchasing the Amphipod b/c of its flexibility. I'm 5'3", 110 lb. Although it took a few tries to figure out how to configure the belt, I finally got it so that the bottles would stay out of the way and I could still reach the pouch to grab my jelly bellies on the run. I wish I could run with the belt on my hips, but it's much more comfortable on my waist. With it on my hips, even though I tightened it completely, it had a tendency of riding up b/c of the movement of my legs or when removing the bottles. Additionally, you could feel the weight of the bottles bouncing more with the belt around my hips (especially in the rear!). Around my waist, the rear bottles sat comfortably on the small of my back (sideways to minimize sloshing). I found that the belt stayed in place as long as I wore it just tight enough to wrap comfortably around my waist. It didn't move much b/c it naturally sat in the curve of my waist (and I don't have curves!), so I didn't feel constricted at all. It takes a little getting used to, but it's not uncomfortable at all.

Some people mentioned that it was hard to snap the bottles in and out. I found this to be extremely convenient since you can access the bottles with just one hand, allowing your other arm to maintain its swing. It takes a little practice to get the feel for it, but it was very easy to remove and replace the bottles in the holster. If you're unsure, just jiggle the bottle slightly to make sure it's locked in place. Again, you can do this all with one hand, unlike with the Fuel Belt. Overall I'm happy with my purchase. I wish the belt part was as comfortable as the Nathan belt, but I need the adjustability factor due to my petite frame. Hope this helps!Get more detail about FuelBelt Helium 4 Bottle Belt.
