Unusual Gear and Accessories?

[FeelsGoodman]

When I look up camera gear and accessories on Google I tend to get the same responses back, camera bag, batteries, memory cards, lenses, etc. 

My question is what unusual gear and accessories have you bought that have been of great use to you?

I am disabled so here are a few things I already own, but looking to try new stuff if it makes things more fun or easy.

Chest harness

Side harness

Sun hood

Window hood

Lens bag with belt loop

A few kinds of straps

Thank you

I made a list of about 5 things and then decided I'd keep it short and sweet.

My favorite carry system for day use is my Black Rapids Sports Breathe.  100% hands free camera carry and it's available to you in 2 secs.  No arm, hand or neck fatigue.  It's probably they best accessory I've ever purchased.  When it's on you can eat, drink and shake hands.  It.also has secondary retention.  I have their wrist strap too.  The carabiner clip on / clip off connections are fool proof.
