DriClime Jacket - Men's
I am 5'10' and got the large, could have gone with the medium. The advantage of the larger size is that you can wear the jacket over more than one layer. I will probably get a medium too! If it were up to me I would change the name of the jacket from DriClime to "THE PERFECT LAYER". Love the napoleon pocket; it's great for quick access for misc items.
I can't really think of any improvements, the Marmot DriClime Jacket is perfect!
