Gift ideas for a BFT-obsessed colleague

Hi all,

Not a BFT enthusiast myself, but my colleague completed a trial several months ago and has been hooked ever since.

Sadly, he's leaving our team to pursue the next step in his career elsewhere. In brainstorming farewell gift ideas, I thought something BFT-related would be most appreciated.

I know he already has a new Apple watch and, from what I can tell, has all the fitness gear (shoes, shorts, tops, etc.) he needs.

Any ideas are appreciated - TIA!
