Spray bottle MSR DromLite 4000 ml Polyurethane White

The MSR DromLite 4000 ml Polyurethane White spray bottle is a high-capacity, collapsible container designed for carrying and dispensing liquids during outdoor activities. Constructed from durable polyurethane with RF-welded seams, the bottle offers a 4000 ml volume in a lightweight, packable form. Its white finish and dimensions — 254 mm width and 465 mm height — provide a compact profile for storage and handling. The interior includes a BPA-free food-grade lining suitable for potable water; the design supports freezing and repeated use. The updated cap design allows filling, drinking and pouring functions to be performed from the same opening.

Advantages

The polyurethane film construction combined with RF-welded seams gives the bottle mechanical durability while remaining lightweight and packable. The large 4000 ml capacity reduces the need for frequent refills, and the BPA-free food-grade lining preserves water taste and safety. Collapsible design allows the container to compress down to about the size of the cap when empty, saving space in packs. The multi-function cap simplifies filling, pouring and drinking without the need for additional attachments.

Suitable for

• Backpacking and multi-day hiking where high-capacity water storage is required
• Field use for group outings, campsites, and team activities
• Travel and sports where compact storage and light weight are priorities

How to use

Open the 3-in-1 cap to fill the bottle with clean water or other suitable beverages, ensuring the inner lining contact is appropriate for potable liquids. Close the cap securely before transporting to prevent leaks. When dispensing, use the cap’s pour or drink positions as needed. After use, empty the bottle and collapse it for compact storage. For freezing, leave some headspace to accommodate expansion and ensure the cap is loosely closed during the freezing process.

Usage recommendations

Rinse the bottle with clean water after each use and allow it to air dry with the cap off to prevent odors. Avoid exposing the polyurethane film to sharp objects or excessive abrasion. Do not use with hot liquids that exceed the material’s intended temperature range. Inspect seams and the cap regularly for wear and replace if signs of damage appear.
