Nathan Hydration Belt 4

This belt was crucial during the hot summer months of training. What I loved most about the belt was that the bottles were 10 oz, whereas my Fuel Belt only fit 6 oz bottles. I only needed to carry 4 bottles versus 6, which also meant easier cleaning. The other thing I enjoyed was that the smaller Fuel belt bottles actually fit into the Nathan Belt too. So if you’re thinking of buying more fuel belt bottles because they’re leaking – just buy a new Nathan hydration belt.
