What Is the LifeStraw Peak Collapsible Squeeze Bottle?
The LifeStraw Peak Collapsible Squeeze Bottle is a collapsible soft bottle with a built-in water filter for outdoor use. Designed for hikers, trail runners, backpackers and travellers, it allows you to carry, filter and drink water from a single lightweight system. The flexible design packs down when empty, helping save space in your pack while providing access to filtered drinking water on the move.
Materials & Technology
Membrane Microfilter
The integrated membrane microfilter features a 0.2-micron pore size that removes 99.999999% of bacteria, 99.999% of parasites and 99.999% of microplastics, along with silt, sand and cloudiness.
This filtration technology is ideal for backcountry travel, hiking and adventures where access to reliable drinking water may be limited.
Peak Series Filter Design
The filter membrane has been optimised to improve flow rate, allowing water to pass through more efficiently while maintaining filtration performance.
This helps users drink, squeeze or transfer water more easily during demanding outdoor activities.
Premium Flexible Materials
Constructed from durable, premium materials, the bottle is designed to resist punctures, tears and abrasion during regular outdoor use.
This makes it well suited to rugged environments where equipment reliability is essential.
Collapsible Construction
The flexible bottle body compresses as water is consumed and packs down small when empty.
Its space-saving design is particularly useful for trail runners, fast-packers and minimalist travellers looking to reduce bulk.
Features and Functionality
Lightweight and Packable Design
Weighing just 102g, the bottle adds minimal weight to your kit while providing both water storage and filtration.
This benefits hikers, runners and backpackers who prioritise lightweight gear.
Multi-Use Filtration System
The system can be used as a drinking bottle, squeeze filter or straw filter, giving users flexibility depending on their activity and water source.
Ideal for those who want a single solution for hydration and filtration.
Leak-Resistant Over-Cap
The over-cap helps protect the mouthpiece and reduces the risk of leakage during transport.
Useful for keeping packs and pockets dry while travelling or on the trail.
Smart Seal Mouthpiece
The integrated mouthpiece is designed to minimise accidental leaks while allowing quick access to drinking water.
This is particularly beneficial during active pursuits where regular hydration is important.
Carry Hook
An integrated carry hook provides convenient attachment to packs, belts or storage points.
Useful for quick access when moving through trails or campsites.
Durable Outdoor Construction
The bottle's reinforced materials offer improved resistance to punctures and tears compared to standard soft bottles.
This gives outdoor users added confidence during extended adventures.
