Product Use

The Magnetic Clip accessory allows you to quickly secure your tube to your strap or jersey, allowing you to more easily access your hydration. To use, attach the strap clip to your pack and the tube grab to your hydration tube. ..

In order to maintain a hygienic reservoir, clean and dry completely after each use. Store in a clean and dry place. Before each use (especially the first use), rinse thoroughly with water. ..

To allow water to flow, bite the soft portion of the valve and suck at the same time. The valve will remain sealed when not in use. To prevent accidental spilling, engage the shutoff by pushing the body of the valve down. ..

Make sure the exit spout is sealed with the Plug-N-Play connector and the Topslider is off. Fill the reservoir with water. Do not overfill max fill line. The reservoir was designed to carry both cold and warm water (-20°F up to 170°F). ..

To open, pull the Topslider sideways from the closed/flared end until removed. Unfold the opening and pull the two sides apart. To close, fold the top molded parts down once and slide the Topslider across the length of the folded area to seal. ..

To connect, push the insert (on the tube) into the body (on the reservoir). You will hear and feel it click into place. To disconnect, push the gray button on the body and pull out insert. The body automatically seals after the insert is removed. ..

Yes, it's safe to freeze your NDURE Reservoir or Soft Flask, but please note: 1. Don't fill it all the way - ice expands and if it's completely full, it could split open the plastic. 2. Be sure not to drop it, as an impact while at a low temperature can cause the plastic to split open.  3. When you remove your Soft flask or Reservoir from the freezer, add a little bit of cold water to it so that it can break up any sharp ice shards that might puncture the plastic film. Otherwise, you're safe to freeze your Soft Flask or Reservoir and enjoy ice cold water. ..
