Daniel O. ★★★★★ Oct 11, 2026

I bought this to replace a cap that cracked after a long hike — it threads on smoothly and seals perfectly, just like the original. No leaks at all, even when I toss the bottle in my pack sideways. Exactly what I needed.

Lost the original cap to my hydration reservoir somewhere on a trail last summer, so this was a relief to find. It screws on snug with no leaking, even when the bottle's rolling around in my pack.

The threading on this cap matches my reservoir perfectly, no leaks after a full weekend of hiking. I tossed my cracked one and now I've got a spare that screws on just as tight as the original.
