I am selling an excellent Advance Progress 3 seat because I decided to reduce my equipment even more. https://www.advance.swiss/en/products/harnesses/progress-3 The seat has a "hybrid protector" which is foam but can be squeezed a lot and does not take up much space. It's a lapel and I could fit the Comet III L in it just fine, along with my helmet, counter, drink and clothes. As a backpack, it is ergonomically excellent and light. I am 184 cm tall and weigh 92 kg, I fit comfortably in the seat. It sits really comfortably and there is no problem with getting on/off. The seat was over fresh water on the SIV, so it has been washed once ;) It has one hook broken off at the helmet net, which I have never used. There is an Advance console for the seat. In case of interest, it is ideal to get in touch on Whatsapp. It is not a problem to come and see and try.
