New way to carry dry powder for events!I don't like to put anything in my hydro bladder except water (too hard to clean). On 6 hour mountain bike rides, I carry 6 of these containers filled with Perpetuem powder, Sustained Energy powder, or Heed powder (the container holds a little over one scoop of each). Every hour, I refill my water bottle from the hydro pack, then empty in one or more containers of my desired powder, shake, and I'm all set. Of course they're great for Endurolyte pills too. The containers are the same ones that come with Perpetuem solids.
