TravelCoat® Nikon 400 VR FL

I've been packing this in my carry-on for two trips now, and the 3mm neoprene is thick enough that I'm not worried about jostling. It slides on smoothly and takes up way less space than my old hard case.

I was skeptical about fitting my 400 into a carry-on, but the custom tailoring of this neoprene cover makes it slide on snugly and frees up space I usually waste on bubble wrap. It’s clearly cut for this specific lens, not a generic sleeve, and the shock absorption gives me peace of mind when I toss

The 3mm neoprene is thick enough to cushion the lens in a stuffed backpack without adding much bulk. Fits snugly but still slides on and off easily, which I appreciate when swapping gear quickly in the field.
