I had a 3L that I loved but my gear was outgrowing the bag. Picked up the 6L and it's my favorite camera bag right now. Perfect size for my A7RV and a 35mm f/1.4 GM, which is my usual combo, another lens, and still enough space for my EDC (wallet, keys, power bank, charging cable, extra battery, etc.).
The Midnight colorway is also fantastic. It's dark and sleek, and the leather accents give it that classic Peak Design feel that makes it look less like a camera bag.
High recommendation from me for the entire Everyday Sling line, having had both the 3L and 6L. Favorite bags to bring around with me on a normal day out.
