The Platypus Platy 2-Liter is an icon in the world of ultralight hiking water bottles. Weighing just 1.3 ounces, this collapsible bottle offers an incredible 70-ounce capacity without adding meaningful weight to your pack. It has earned a stellar 4.7-star rating from over 3,000 verified buyers, making it one of the most trusted hydration solutions on the market.
What sets the Platy bottle apart is its simplicity and reliability. Made from BPA-free, BPS-free, and phthalate-free materials, it features a food-grade polyethylene lining that doesn't retain flavors or give your water a plastic taste. When empty, it collapses and rolls up small enough to fit inside your pocket — perfect for hikers who need to pack light for long distances.
The bottle has a stable base that stands upright when filled, which is surprisingly handy around camp. It accepts Platypus caps and drink tubes, and it pairs perfectly with the Platypus GravityWorks water filtration system for group trips. This versatility makes it more than just a water bottle — it's a component of a complete hydration system.
Pros: Incredibly lightweight at 1.3 oz, massive 2-liter capacity, no plastic taste, collapses to pocket-size, BPA/BPS-free, compatible with filters and accessories, stable base when full.
Cons: Narrow mouth makes filling and cleaning slightly harder, not as durable as rigid bottles, can be punctured if handled roughly, no insulation for cold water.
Best for: Thru-hikers and ultralight backpackers who prioritize weight savings above all else. Also great for campers who need bulk water storage without the bulk.
We recommend the Platypus Platy for its legendary reliability and weight-to-capacity ratio. When every ounce counts on a multi-day hike, this bottle delivers the hydration you need without the weight penalty of traditional bottles. The 3,000+ positive reviews speak to its proven performance on trails worldwide.
