Does anyone use a Cotton Carrier with large telephoto lenses?

I just ordered a Cotton Carrier G3 dual harness system. I've seen these carriers around for awhile but never thought about them due to how bulky they are. However I could never figure out a way to hike distances while having my camera and larger lenses (sony 70-200GM and 200-600G) mounted. On a strap they swing too much, and the gear smashes into things, and on a camera clip like Peak Design they weigh down backpack straps too much / put an uncomfortable amount of weight on one shoulder.

So after watching a few reviews I decided to give the Cotton Carrier a chance since Adorama had a sale on the dual setup with the bino mount so I ordered it last night. Anyone else use this system for large telephotos? I'm mainly worried about if I'll still have mobility with the 200-600 on the front of my chest. Anyone have pros, cons, tips, or tricks while using the Cotton Carrier?

I'm a big fan of the Cotton Carrier. I use mine at air shows with my Canon 300 f2.8 IS II.
It also worked well with the 400 DO II and 200-400 that I rented.

It puts the weight on your shoulders, instead of the neck. My only wish is there were a bit
more padding on the carrier at the shoulder area. But the way it is now is fine.

If you look at the video, one must rotate the camera/lens 90 degrees to remove it from the hub.
In this way the camera/lens is locked in place and can't accidently fall out of the carrier.
However, at air shows I walk on a flat surface. No chance of it falling out. So I mount the hub
rotated 90 degrees from how the instructions show it to be mounted. This way I can remove
the camera/lens by pulling straight up from the carrier. Easy in, easy out. Like a gun in a holster.

But if one is hiking, biking, or bouncing around a lot, then mount the hub as instructed.

I also use a tether from the camera to the carrier, for safety, in case the camera slips from my hands.

I also put a drop of Locitite Blue 242 removable thread locker on the hub screw.
And a squirt of PAM cooking spray on the hub for lubrication. Makes removal-insertion a little
bit easier.

I have a similar product that I used to carry my 7D markII with a Sigma 150-600mm lens. It was much cheaper than the Cotton Carrier and looked almost the same, build quality might be the difference, I didn't care for the stock hub adapters that screw into the tripod socket, I replaced them with heavier duty metal ones. It worked pretty well for me, mine is a Movo MB1000 branded one that I got from Amazon for $32.99 back in 2016, the upgraded hubs were Movo MB1000CH, they were another $14.95.

Good idea, I used the tethers but the rotating to remove the camera sometimes would loosen the hub.

Good advice. Thank you for your input. I'll have to hit it with a spray of quickdraw that I use for my kydex holsters. Did you own the newest carrier (G3)? It looks like they've made significant upgrades since the first carriers were introduced, but I'm not sure if they've upgraded the padding or not.

My CC is about 8 years old. I don't remember the model number (if it had one). But it's still holding up well.
I believe you'll enjoy yours.

I've been using the CC Vest for about a decade now. For hiking with a long, heavy lens, it's a must. I've used it mostly when I had the Sigma 150-600, but when I sold it recently, it's now to carry the RF 100-500 with the 1.4x and sometimes the RF 800. I use either a Peak Design Slide Strap or a Black Rapid Breathe Curve Strap, both of them modified with the PMG QR plug, as a safety tether around my neck while using the CCV. For something as long as the RF 800, I turn the lens horizontally. Any lens that's long enough to hit with your knees while hiking uphill, just turn it horizontally.
