You definitely need to try or be prepared to return as the fit is not that adaptable.
Fit, looks and heat are all very personal things but mine fits like a glove, decent ventilation for the level of protection it offers and I love the CHIPS meets Flash Gordon styling of mine! Not too hot for 2-3 hour rides where I push more on the DH than the climbs in 10-15 degrees, you do feel the heat when it’s over 20 or hammering the climbs – t it is warmer than some, as you can tell from the looks.
It has been perfect, almost forget it’s on and enough protection for hammering the descents – would buy another straight away if I ever need to.
