Hi,

I'm about to pull the trigger on a Gore jacket on sale but I'm uncertain about the fit, never having owned any Gore tops. Their men's sizing chart says

Size S M L XL XXL
Chest 32.75 - 34.75 35 - 37 37.5 - 39.5 39.75 - 41.75 42 - 44
Waist 28.75 - 30.75 31 - 33 33.5 - 35.5 35.75 - 37.75 38 - 40
Hip 33.5 - 35.5 35.75 - 37.75 38 - 40 40.5 - 42.5 43 - 45
Arm length 29.75 - 30.75 31 - 31.75 32 - 32.75 33 - 33.75 34 - 34.75
Inseam 30.75 - 31.25 31.5 - 32 32.5 - 32.75 33 - 33.5 34 - 34.25

My chest size (38-39) indicates I should get a large. However, all of my current cycling clothes are medium, so I'm reluctant. Do Gore tops run small?

Thanks
