I had a Rolan pro cover on my 200-600 that I just sold and was happy with it. This time I purchased the chasing birds brand for the 600mm as I've heard really good things about their covers and I preferred the colour scheme. I just received it (before the lens) and it feels great quality, more padded than the Rolan pro. Can't speak to fit yet.
Tried out Chasing Birds with the 400-800 and the quality was nicer than my outdoorphotographygear 200-600 cover.
While my 400 F4.5 & 600 F6.3 were on pre-order I ordered covers from Chasing Birds. On arrival I found out I had mistakenly picked the wrong camo pattern. Customer Support quickly sent me a replacement after I provided tracking info for exchange. My order was from AliExpress, shipped from CN but the return address they gave went to Portland, Oregon.
