TravelCoat® Fuji XF 500mm f5.6

I was worried about fitting this into my carry-on, but the custom tailoring makes it snug without being bulky. The closed cell neoprene feels dense enough to handle a knock against a seat armrest.

The 3mm neoprene has just enough squish that I stopped babying my bag on hikes. It slides on snug and stays put, and I like that I can toss the lens in with my clothes instead of a bulky hard case.

Slid this over my 500mm before a rainy hike and it stayed bone dry in the pack. The neoprene hugs the lens snugly without adding bulk, so it still fits in my camera bag. Way better than wrapping it in a jacket like I used to.
