try this on....burton size chart not reliable
I got this jacket when Burton replaced a jacket of mine under warranty. A couple of things to note: the sizing seems a little bit "off" to me. I had an old AK jacket in a medium and it was a bit tight in the chest. I am 5'5", 140, and a 34-D. When I got this new jacket, I got out a measuring tape and went by the size chart. I ordered a large, and when I got it, I was swimming in it! It was huge. The sleeves went way past my fingertips, and I have long arms. The chest, waist and shoulders had lots of extra room. Also, the shroom color was more of a purple than a blue. I returned it and am waiting on a new jacket in SpaceDye in Medium. Hopefully the medium fits.
Things to note: The jacket is toasty warm, and the interior is lined with a fuzzy material. As with all burton gear, this is a quality jacket. I would simply recommend going with your normal size or be prepared to exchange if you go by the size chart's sizing.
