I have both Arlen Ness and Rst Fusion one piece suits. As mentioned earlier the velcro on the RSTs can be a pain and a little shorter fitting but can’t fault them. Arlen’s fit well and no obvious faults. Both suits zips are fine. I tend to use Scott Leathers for kicking about in n one pieces for day tripping lol
i have a set of RST two piece, its an R16, and i think the quality of it is really good, probably better thatn my dainese laguna seca suit. I also think RST has some decent cred
I had the RST Razor two piece for about 6yrs with no issues what so ever. Sold it to get a tractech Evo 2 two piece. I've had the TT2 for about 4yrs and no issues apart from the velcro by the neck isn't sticking so well.
I’ve had the RST Tractech Evo 2 jacket and jeans for three and a half years now, only issue I’ve had is the stitching on the Velcro on one of the cuffs started to come out. Other than that, for me super comfy and don’t feel at all restricting.
