Sportful Jacket Sizes
 

Hey Guys,
I wanted to pick Sportful Hot Pack No-Rain Jacket, but wasn't sure about what size to get. I've never bought a jacket for cycling so I'm not sure how fitting it should be. I'm about 5' 11 and 135-140 lbs. I usually wear smalls, but sometimes mediums. Their sizing says that the small is 92 cm for chest and 80cm waist and the medium is 96/84. I guess if I'm not sure I should pick up the medium? Also if anyone has opinions on this jacket, that'd be awesome too! Thanks in advance!
