Great ICU if you have a lot of gear and/or big lenses

I recently bought this ICU to use it with my Tilopa DuraDiamond backpack. I bought this ICU mainly because I wanted an ICU capable of accommodating a body with a big lens attached. In my case I have a Nikon Z8 and a 180-600mm. In addition to this, I stored also a second body with a zoom lens attached, a few other lenses and accessories.

The Perfect Protection

I put a Pro XL ICU in an Ortlieb Atrack 45L backpack. It was used daily for the past six weeks and went from Svalbard to Tanzania to Kenya and back. It held a Nikon Z9 & Z8, 1.4x & 2x converters, 14-24, 24-70, 70-200, 180-600, multiple batteries for both cameras, chargers and several sizes of filters perfectly. It protected the equipment during 21 separate flights, untold kilometers bouncing around in the back of safari Land Rovers, several tuk tuk and taxi rides, and a thousand kilometers onboard a ship and in the bottom of zodiacs. The whole time it has worked flawlessly in some very demanding conditions. Getting lenses, bodies and all the other stuff in and out of it, has been easy. I'll be ordering another one soon for my other Atrack backpack to hold another Z9, 600 f4., 100-400 and a 28-135. I have no doubt that it will work perfectly and protect this set up as well.

Excellent ICU, fits all my gear and more

I use this ICU often as it fits in several packs that I own and holds everything I typically carry which is a Nikon Z9, 14-24, 24-70, 100-400, drone & controller, extra batteries, filters and other random items. Padding is great and doesn't fray like that Shimoda's do. Buy this ICU, you will not be disappointed!

Outgrew the L ICU, needed an XL ICU, works great

I have several F-Stop bags and the largest ICU I had was the Large Pro. I purchased a new lens that would not fit in that ICU, so ordered the XL Pro which fit great in my Ajna and holds all the gear I need to carry. I am a huge fan of F-Stop and am also very impressed with their customer service.

Love it!

The XL ICU fits perfectly in the YETI Panga 28 L! I now have a waterproof and bulletproof camera bag.

Love having the extra capacity in my Tilopa

The Pro Large “FILLS” the Tilopa. It allows me to carry my larger lenses with ease . . . I even insert them down high in my bag - up under the top zipper because I would not be able to reach smaller items that high above the opening. Front the top opening - there is room on top of the insert for 1 thin gear bag.
