27oz Wide with Loop Cap

Took this on a four-day hike and it fit my backcountry filter without any adapter, which saved me a ton of hassle. The loop cap hasn't leaked once in my pack, and the 27oz size is just right for a half-day stretch.

The wide mouth is a lifesaver for filling up at stream crossings without spilling everywhere, and it threads onto my filter setup without any fuss. Lightweight enough that I barely notice it in my pack, yet it handles the rough trail days without cracking.

I’ve been stuffing mine with ice cubes every morning and the wide mouth makes it so easy, plus it threads right onto my filter for refills on the trail. The whole thing barely adds any weight to my pack, which I really appreciate on longer hikes.
