Great for hydration on shorter runs or carrying personal fuel mix during races. When strapped to my SPIbelt, there is no bounce or discomfort. Highly recommended!
I ran the Chicago Marathon with the SPIbelt carrying all of my nutrition, and the SPI H20 Companion 8oz water bottle clipped to it. Both were amazing and gave me zero issues! I don't like carrying items in a vest (slows me down) or in my hands (fatigues my arm) so having them around my waist is perfect for me. Once you find the perfect adjustment for you, there is no bouncing and you'll forget it's there. While 8oz isn't enough to last through a marathon I was able to keep my electrolytes/salt solution in the bottle so I could sip throughout the race and it was really reassuring that I had some liquid on me in-between water stations. Any bigger of a bottle and I think it would add too much weight, so the 8oz is a great size. I plan to use this on shorter runs/walks/hikes too so I can be hands-free. Might even be a good idea for the kids so they can carry their own water hands-free, too. Totally worth it!
Great products and exceptional customer service.
I use nuun hydration tablets in my water bottle. A nuun tablet is for 16oz of water. To use the SPI H20 bottle I have to cut the nuun tablet in half. Kinda inconvenient.
I don't know how well the belt would hold up with 16 oz of water attached to it. If I were to change anything a 16 oz water bottle is what I would want.
Will be giving this to my sister for her birthday at the end of August. She will love it! I also got one for myself
