WANDRD Essential Camera Cube - Packing Cubes for Camera Accessories - Tech Organizer for Travel Accessories - Fits PRVKE 21L Camera Bag

I use this to carry my Sony full-frame camera and a 24-70mm lens in a backpack. Still has room for more. Fairly basic, but so far so good.

This is a well constructed packing cube that I got so that I could use a lightweight backpack as a camera bag on an international trip. It mostly did the trick but was a little on the small side for my small mirrorless Canon M6 mark ii with a 70-200 lens attached, plus another lens. Otherwise than being a little smaller than I hoped it is a nice cube that can be used in a larger bag or with a strap attached alone. It has a small handle on it, attach points for a strap, and two different points of entry. Very good quality.

There's no way you can fit a full frame mirrorless camera with a decent size lens plus another zoom/telephoto without cramming them in. This whole 21L system from Wander is hyped up junk. Save your money and get a Tenba Fulton V2. Yeah, it's not made from Tarpaulin, but the Wandrd bag is heavy and stiff and you can fit more in the Fulton.
