I am 510 and I got the large. Its pretty big but proportionally it
looks good for the oversized style. This is only a wind resistant shell so on
colder days you need to layer up. There is plenty of room for me for base
layers and sweaters. The glow in the dark graphic logo is a cool design
gimmick which really gives the jacket an accent. Not too much, just
enough. Super comfortable to ride in on the mountain and in the park.
Gives you plenty of room for your joints so it is no problem moving around.
Only spot that feels a little slimmer is the neck/collar area. I have to
zip the jacket up all the way or the velcro pads rub against my chin too
much or get caught on my helmet straps. This is not a problem on some
other jackets I have with a little looser fitting necks/collars. Very good
pocket design. Large front pockets come in handy when I am not riding and
need a place to stash the wallet gloves etc. Other jackets are over loaded
with features which are actually distracting and don't get used. Overall this is the coolest
jacket I have gotten and to be honest its not a bad price.
