No. All Platypus hydration products are 100% BPA-, BPS- and phthalate-free, and do not use polycarbonate.

Congrats on your mud-packed adventure! To clean your pack, hand wash with mild soap. For simpler cleaning, rinse off your pack with a hose.

For the best care, use a technical garment soap. Hang or lay flat to dry, avoiding direct sunlight.


Tip: Use the rainfly on your ride to reduce the need for deep cleaning (Included in all of our A.M. packs).

Yes, you can shorten the length of your drink tube. Depending on the model of your hydration reservoir, you simply trim the tube down to the desired length.

If you have a Big Zip™ EVO or Hoser™, trim the tube from the end with the bite valve. For the Big Zip EVO, simply remove the shut-off valve, trim to the desired length, and re-insert the shut-off valve. For the Hoser, remove the bite valve, trim to the desired length, and re-insert the bite valve.

If you have a Big Zip™ LP, trim the end of the tube that mates with the quick disconnect at the base of your reservoir. You can trim from either end, but trimming from this end is much easier!


Detailed instructions on how to do this are provided in your pack’s user manual, which can be found on your pack's online product page.

No, the waist belts on our hydration packs are not removable. However, you can wrap the waist belt straps around the back of the pack, securing the straps through the light loop. This will keep the straps stowed when you don’t need them and accessible when you do.

To disinfect your Platypus hydration reservoir:

  1. Fill it with a solution of unscented household bleach and water, using a concentration of 2-5 drops per liter of water.
  2. Close the reservoir and swirl for 10 seconds.
  3. Squeeze the bite valve to flush the hose and valve, being careful to keep the valve opening over the sink. Leave filled overnight.
  4. Dump the solution and rinse the hydration reservoir (including hose and bite valve) three times with hot water, then air dry.

Note: for an eco-friendlier option, use a chlorine-free, hydrogen peroxide-based bleach alternative.

Yes. Periodically adding a little Vaseline to the tracks will keep them supple and easy to close. Wipe away any excess Vaseline. In the field, a little lip balm or water can do the trick.
