Good gear to have

As a believer in ATGATT (All The Gear All The Time) I often find myself trying to enjoy a nice summer day in the city or local artists community or whatever my day’s destination lugging around a helmet and a heavy jacket because I have no way to store them safely on the bike. Helmet locks are available, but there’s really not much that can be done with your coat, gloves, etc. if you don’t have fairly large locking saddle bags.
Then my brother found this nifty gadget in an outdoor store. The PacSafe is a stainless steel mesh bag that you can use to “Throw … around your pack, secure … to something fixed and get on with your adventure.”  While it’s designed for backpackers, instead imagine your helmets, jackets, gloves, throw-over saddlebags and anything else you want secured in the bag. Just load it up and lock it to your back rest, rack, or any other part of your bike and your gear will be be kept safe until you return.
It comes in various sizes, with the medium size being most suitable (in my opinion) for two helmets and jackets. When folded it takes up practically no space, with closed dimensions of approximately 6 X 4 X 2 inches. And priced under $100 it’s significantly cheaper than a single lost helmet or jacket.
I won’t leave home without it.
