フュージョン™ 3L グループリザーバー TRU® ジップ防水ジッパー付き

Three liters got me through a full day of hiking without a refill stop, which is exactly what I wanted. The waterproof zipper seals tight enough that I never worried about leaks in my pack.

That TRU Zip zipper is the real deal — no leaks in my pack even when I stuffed it sideways. Filling the 3L is quick and the wide opening actually lets me get my hand in to dry it out.

Just did a 12-mile hike with the 3L reservoir and never once had to stop to refill. The TRU Zip waterproof zipper is the real win here, no leaking or dribbling down my back the whole day.
