Platypus Softbottle 1,0L Platy Logo Closure Cap

The Platypus Softbottle 1.0L Platy Logo Closure Cap is an ultralight collapsible 1-liter bottle weighing 34 g, made of BPA-free plastic with a screw closure. The standard 28 mm PCO neck accepts Sawyer squeeze filters, letting the bottle double as a reservoir for field filtration. The cap includes a loop for clipping to a carabiner. The material is food-grade certified and the bottle is dishwasher-safe, making it easy to keep clean between trips. Compared with a rigid bottle it saves significant weight, and rolled up empty it packs down to almost nothing. It's a straightforward, no-frills choice for an ultralight kit. Unlike variants with a push-pull cap or an integrated drink-tube kit, there's no way to sip on the move, which can be a minor limitation on days with frequent hydration stops.
