The UltraFlask™ 500 ml + Filter Kit is a compact and efficient solution for safe hydration, designed to provide clean water on the move. With a flexible and compressible design, it fits securely in hydration packs and vest pockets, ensuring stability and comfort while reducing bulk as you drink. The 42 mm wide opening allows for easy filling at water sources, and the bite valve delivers smooth, drip-free sips with every drink. The secure grip simplifies attaching and removing the filter, while the included backflush adapter restores flow rate for long-lasting use.
