The Streamer SQ 1.5 L fits perfectly in a hip bag or hip pack. Its shorter, wider shape makes maximum use of the available space, and still leaves enough room for tools and snacks in your hip bag. The drinking tube is standard length and compatible with all hydration models in the range. Easy-to-use and reversible for better cleaning and drying, the Streamer SQ 1.5 L is a great addition to your hydration set-up.
