Why You’ll Love It
I switch between electronic construction drawings to meeting notes and field sketches as well as personal journaling. The FFB5 is exceptional at containing it all together... I now have the tech along side the analogue at all times.

Allows me to use the P52-LG planner and standard comp notebooks. My work necessitates a lot of notes and this folio helps me to stay organized without being as large as the binder I used when I was in the field full time.
— Joseph C.
Considering that I use a regular composition notebook with a giant rubber band out on jobs as a landscaper, this Lochby B5 fit my needs perfectly. My book is no longer an embarrassment, everything stays clean, dry, and neat, it's exactly what I wanted and needed for jobs on the go.

FAQs
Please read our FAQs page to find out more.
Why is the zipper designed this way?
We designed the zipper to rest on top when the folio is fully open. This keeps the writing surface flat and free of bulges, so nothing gets in your way while you work.
The zipper’s position also determines where the pen pocket goes—keeping it on top makes it easier to access and keeps the folio clean and functional when closed. Read more.
