    After being selected in the Western States Endurance Run 100 (a cupless race) lottery for 2016, I purchased several of these cups (for myself as well as for my pacers/crew). They are made extremely well, and are lightweight and collapsible as advertised. A cup will easily fit in a pocket of my shorts or in my racing vest without taking up much space at all. I really look forward to practicing with them in the next few months then putting them through their paces at the end of June. Highly recommended.

    Very nice product for keeping the race course of any distance a little cleaner. Plus no germ worries from pre filled cups sitting there.

    no racer should be without their own personal cup! This C2Cup is great. Once you’ve used it swish it out with water and stuff it into your pocket ready for the next aid station. So much better than using a communal cup or adding to the heap of used cups heading for the landfill.

    Love this cup!
    Purchased 4, one for each of my running buddies and one for myself. Folds up small enough to fit in a zip pocket in my running shorts. No more wasting paper cups!

    I use this cup for camping and hiking and it’s great! Fold it up, use it, swish it out, fold it up, done! Also great to have since no sharing allowed right now. 🙂
