Cascade Designs has announced a new line of Platypus Origin hydration packs.

The five-strong range of weatherproof, lightweight hydration packs are designed with performance, comfort and customisation top of the agenda.

A taste-free Platypus Big Zip SL reservoir is the foundation of every pack in the line, built to accommodate both the two-litre and three-litre sizes without affecting the capacity of the pack itself.

Further design enhancements include pressure-relieving BioCurve ventilated back panels, stretch-woven fabric for comfort on touch points and storage and loops for gear and helmets.

“With 10-plus years testing and perfecting hydration reservoirs, we’ve tried a lot of packs,” said Cascade Designs division director Erik Flink.

“We recognised the need to build a pack from the ground up, with our Big Zip SL reservoir as the foundation.

“This line is the result of countless hours of obsessing over the details using the same design attributes we apply to all Platypus products-deliver maximum performance as simply as possible-and our testers have been thrilled with the results.”

The new Platypus Origin hydration packs include:

Origin 3 – Built for one to three hours of activity, this pack includes a two-litre Big Zip SL reservoir and three litres of weatherproof storage.

Origin 5 – Built for two to four hours of activity such as an ultra-light half-day outing or a quick trek. Pack includes a two-litre reservoir and five litres of weatherproof storage.

Origin 9 – A full-fledged day pack designed for everything from cold weather hiking to all-day summer epics. Pack includes a three-litre reservoir and nine litres of weatherproof storage.

Origin 22.18 and 22.20 – Ideal for fast-packing overnights, some features are removable to lighten the weight. Pack includes a two-litre reservoir with 22 litres of weatherproof storage and is available in two torso lengths.

Origin 32.20 and 32.22 – The largest Platypus pack is the mainstay of multi-night fast and light trips, as well as overnight alpine scrambles and gear-intensive day use activities. Pack includes a three-litre reservoir with 32 litres of weatherproof storage and is available in two torso lengths.
