Platypus Platy 2L Bottle Review (2026)

By Grant — Last updated 2026-07-03 — hydration

Grant's Verdict

9/10 — Top Pick

Platypus Platy 2L is a coextruded polyethylene film bottle that weighs 1.4 oz empty and folds to wallet size. The taste-free film provides no plastic off-gassing at any temperature. Works with Sawyer Squeeze and any squeeze filter directly.

The Short Version

Platypus Platy 2L is the ultralight water carrier for thru-hikers. We tested Sawyer Squeeze compatibility and compared it to Smartwater 1L bottles for pack water strategy.

Who This Is For

Buy this if: Thru-hikers and ultralight backpackers who carry multiple water bottles and want minimum empty weight.

Skip this if: Car campers or anyone who wants a rigid bottle — Platy collapses and can't stand upright empty.

Pros & Cons

Pros

  • 1.4 oz empty — lightest quality 2L carrier available
  • Folds to wallet size when empty
  • Direct Sawyer Squeeze thread compatibility

Cons

  • Can't stand upright empty — not a camp use bottle
  • Film is thinner than rigid bottles — handle with care at edges

The Detailed Breakdown

Squeeze Filter Compatibility

Platypus 2L threads match Sawyer Squeeze standard threads. Fill the Platy at a water source, attach Sawyer Squeeze, and drink directly or squeeze into a clean bottle. The soft walls squeeze easily — better than the rigid CNOC Vecto for hand-squeeze operation.

Grant's Final Take

The correct carry bottle for serious ultralight backpackers. Pair 2x Platy 2L with a Sawyer Squeeze as the water system.
