30oz GeoPress® Nesting Cup & Lid

Still have to see how to set it up with the pre filter and find out if it fits in between the grail and it or over both for a super nice setup, hopefully a French press for that size but combo is a no brainer

Grayl nesting cup

The cup itself is just a little bit bigger in diameter the the Grayl bottle. But that is actually a good thing. If it gets a dent or deforms a little bit, the bottle will still fit. As a solution for those that want a snug fit, wrap a larger rubber band around your bottle, or set a clean rag over the cup, and press the bottle in. Then you have a rag to wipe debris or residue out of the cup. But it works great for what it was made for.

I chose this to add to my Geopress that I use for travel. It fits around my Geopress perfectly. The cup is super sturdy. I was surprised how well built it is. The lid fits tightly even when turned upside down (when it is empty). I have not used it outside yet but have no doubt it will hold up to anything I throw at it. Totally recommend. :)
