The Brunton Zip Tag-Along Compass is a small and lightweight compass that's designed to attach perfectly to the zipper of your jacket for easy use.
Brunton says:
Integrating the revolutionary BRUNTON O.S.S. system into a small, tag-along compass, the new Zipper pull compass also features a tough, compact base plate and 5 degree resolution.
The clue is in the name. This handy little compass can easily be fitted to the zipper of your jacket so it can tag along with you on your adventures. Alternatively it can be stored in any small pocket ready for when you need it.
It is a high quality product just like all Brunton gear and is ideal for helping you maintain your heading without digging for your primary compass. This ultra light and compact compass won't leave you out of pocket either.
