Platypus collapsible water bottle 2L Ultralight 70oz - featherweight, stands upright

The Platypus Platy 2-Liter is an ultralight, collapsible 70-ounce water bottle that packs down small for travel and backcountry use while remaining safe, flavor-neutral, and compatible with Platypus caps and filters.

Compact but capacious, this soft-sided bottle gives you two liters (approximately 70 ounces) of liquid storage in a package that weighs only 1.3 ounces. When full it expands to a stable, self-standing shape; when empty it rolls up to fit into a pocket or the side of a pack. The food-grade polyethylene liner is formulated to avoid plastic taste and does not trap flavors, so it’s useful for water, juice, or other noncarbonated beverages during multi-day trips, commuting, or travel.

How durable and leak-resistant is this soft bottle?

Despite its featherweight construction, the Platy bottle is built to withstand typical outdoor use. The screw-top closure secures liquids during transport, and the reinforced base expands to provide a standing profile when filled. Avoid sharp objects and prolonged abrasion to maximize lifespan.

• Ultralight 1.3-ounce weight for minimal pack burden
• Screw top keeps contents secure against spills
• Stable base allows the bottle to stand upright when filled
• Made in the USA with manufacturer limited lifetime warranty

Can I attach a filter or use different caps with the Platy?

Yes — the Platy 2-Liter accepts all Platypus caps and drink tubes and pairs directly with Platypus filtration systems like GravityWorks. That versatility makes it easy to transform the bottle into a filter-fed reservoir or integrate it with hands-free drinking setups.

• Compatible with Platypus caps and drink tubes for quick swapping
• Works with Platypus filters and GravityWorks systems for treated water
• Use with a wide-mouth cap for faster filling and cleaning

How does this bottle handle storage and flavor retention?

The internal liner is food-grade polyethylene engineered not to retain odors or tastes, so you can switch from water to other beverages without lingering flavor. When empty, the bottle collapses and rolls small for efficient packing or stashing in a bag pocket, freeing space for other gear.

• Food-safe polyethylene liner resists flavor carryover
• Collapses flat and rolls up small for compact storage
• Easy to clean and dry when opened wide

What are the size and weight details I should know?

The Platy holds a full 2.1 liters (about 70 fluid ounces) and measures roughly 13.8 by 17.5 inches when fully expanded. At only 1.3 ounces empty, it’s intentionally light for fastpacking, backpacking, and travel where every ounce matters.

• Total capacity: 2.1 liters / 70 ounces
• Expanded dimensions: 13.8 x 17.5 inches
• Empty weight: 1.3 ounces for minimal pack weight

Who is this for? The Platypus Platy 2-Liter is made for ultralight backpackers, thru-hikers, and travelers who need reliable, high-capacity hydration without bulky hard bottles. It also suits campers, festival-goers, and families who want a safe, reusable container that stows cleanly when not in use. If you value pack space, low weight, and compatibility with filtration and cap systems, this bottle is a practical, flavor-neutral choice backed by a limited lifetime warranty.
