Our roomy all-mountain hydration pack created for women, the Siouxon (Sue-sonn) AM is made for a full day of riding. It offers ample room to pack and organize your riding essentials, 3 liters of fast-flowing hydration with the new, taste-free, Big Zip EVO reservoir, the airy FloatAir back panel to keep you cool and ventilated. It offers a stable, tailored women's fit to keep you comfortable all day long. Available in 10.0L & 15.0L sizes.
  • Women's Fit: Designed and built for optimal fit and comfort, pack features soft-touch materials at body contact points, an optimally sized back panel length, anatomically shaped and angled waist belt and shoulder straps, as well as long-track sternum strap adjustment.
  • FloatAir back panel: Highly breathable mesh is tensioned over a lightweight wire frame, floating the pack over your back and optimizing cooling airflow; the wire frame is reinforced to help prevent the pack from compressing against your back, maintaining airflow.
  • 3.0L Big Zip EVO reservoir: Premium taste-free and BPA-free water reservoir features a 50% faster flow rate, low-profile shape, wide-mouth opening that seals securely, and a convenient quick-disconnect hose.
  • Easy hose routing: The drink tube can easily be routed on the right or left by threading the hose through the webbing loops on either shoulder strap (note: routing over the right shoulder is recommended, as it allows the bite valve to easily return and reattach to the magnetic clip).
  • Smart hydration pocket: Hook and loop closures hold reservoir securely in place while you ride; dedicated hydration pocket makes it easy to access reservoir for refilling or cleaning.
  • Full-face helmet and pad carry: A front stash pocket with adjustable straps, quick-release buckles and stretch side pockets securely stow a full-face helmet and protective pads.
  • Tool organization and separate pump sleeves: Main compartment features a zip mesh pocket with key retainer and three mesh stash pockets to organize tools, repair kits, snacks, and other gear for easy access; two pump sleeves conveniently secure a shock pump and tire pump.
  • Fleece-lined eyewear pocket: Located at top of pack for fast, easy access, the soft fleece lining of the pocket protects your sunglasses and phone from scratches.
  • Waist belt zip pockets: Two zippered pockets on the waist belt stow smaller riding essentials like energy foods for fast, keep-your-pack-on-your-back, on-the-go access.
  • Rainfly: Protective rainfly can be quickly deployed from its dedicated pocket on bottom of pack for on-the-go protection from rain and mud; it can also be detached for easy post-ride drying and cleaning.
  • Reflective detailing: Reflective hits enhance your visibility to others when you're on the trail or traveling between rides.
  • Light loop: Attachment point for rear blinky light.
  • Magnetic hydration hose retention: Offers clip-free access to the bite valve.

Do any of your packs come with a rain fly?

Yes, our A.M. packs all come equipped with a protective rain fly that is stowed away in the bottom of the pack.

The rain fly can be found in its own zippered pocket at the base of the A.M. packs. It can also be detached for easy post-ride cleaning and drying. We strongly suggest removing the rain fly and allowing it to dry separately when wet. To re-attach, simply clip the fly back in and zip the pocket up.

Do any of your products contain BPA, BPS, phthalates, or use polycarbonate?
No. All Platypus hydration products are 100% BPA-, BPS- and phthalate-free, and do not use polycarbonate.
My hydration pack got really muddy. How do I clean it?

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).

My hydration pack’s drink tube is too long—can I shorten it?

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.

Can I remove the waist belt on my hydration pack?
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.
How do I disinfect my Platypus filtration system?

To disinfect your Platypus filtration system, fill it with a solution of unscented household bleach and water, using a concentration of 2-5 drops per liter of water. Close and swirl for 10 seconds. Leave filled overnight.

Filter solution through any filters and/or hoses, then rinse system (including filters and hoses) three times with hot water. Let air dry.

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

The zipper tracks on my reservoir are hard to close. Can I make it easier?
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.
Can I get small replacement parts for my pack?

Many replacement parts can be purchased directly from us online on our Accessories page or from one our retailers. If you cannot find what you’re looking for, our friendly customer service team can assist you:

For customers outside North America, please consult our International Distributor listings.
