I have the 2019 carbon MIPS version. I wouldn’t say it’s particularly light.
I use it for uplift / DH days as i find it far too warm to pedal around in. It is comfortable and does offer a LOT of protection.
I also have the proframe Neeko mentions this is better suited for pedalling around in but doesn’t offer anywhere near the amount of protection as the rampage but it is a lot lighter.
The fit of the proframe is a little strange, it’s not as immediately comfortable as the rampage but you soon get used to it.
Depends on the type of riding you mainly do really. If your always in the bike parks then definitely the rampage, if you have to do a bit of pedalling then the proframe would probably be better suited but could still get hot if your doing a lot of pedalling.
