I ordered and tried on the Sann shorts. They were nice and VERY comfy, but I felt the material was rather lightweight and might snag or get friction/rubbing damage too easily. Personally I like a heavier more supportive fabric. If you are looking for lightweight breathable shorts they would be good. I can't recall much about the chamois to be honest- I don't remember whether it was thick or thin. I ordered the shorts because they were supposed to be good for long distance though, so the chamois is probably good.
I opted for the Shebeest Ultra D shorts instead of the Sann- heavier fabric and liked that they had less tight leg bands.
