When Wren set out to craft a field journal that could handle the elements, they knew exactly who to call. Karst specializes in tear-resistant, super-hydrophobic (read: waterproof) tree-free paper made from repurposed construction waste. Each of their pages has zero grain for friction-free writing, plus a dot grid for lined-paper tidiness—without the lined-paper looks. The A6 size fits easily in your back pocket, and the back cover has ruler markings for quick, on-the-go measurements.

And what's all that great, weatherproof paper without a trusty utensil to put your thoughts down with? We bundled the book with an equally dependable Grafton pen from Everyman. It's got a body of 100% anodized aluminum, perfectly weighted for that substantial feel. We included an exclusive ballpoint insert, chosen for its compatibility with stone paper. The deep-groove grip stays faithfully in hand, and that bolted-on clip isn't going anywhere, trust us.
