Marmot Ion Windshirt - Women's - 2009 BCS

Excellent shell for distance running. I am 6' tall, 165 lbs and I have a Large. The fit allows you to wear a light fleece top or regular tshirt underneath. The back hem hits halfway across your bottom so there is plenty of coverage and warmth. The chest pocket is convenient for ID/ credit card and has a loop for a key chain. The hood can be a little annoying ( not removable) but it can be rolled and there is a tab to hold it in place. It is not waterproof, but it really cuts the wind and will keep you dry in a heavy fog or sprinkles. It retains a little smell after you sweat in it a few times, but airs out quickly. The color is a brilliant bright blue. Overall a great jacket.

Everything about this jacket I absolutely love. It's great for XC with some Smartwool unders and a waterproof fleece. The only gripe that I have is that "willow" looks like a sage green, and it's definitely no where near that. It's a much brighter green. However, I don't hate it! It's still a great color, and is nice and visible in the backcountry.

I have this jacket in a size small in a silver color. I bought it directly from Marmot so that might be why there is less colors here. Either way regardless of this this jacket is great. It is very lightweight and fit me perfectly I am short around 5 ft 1 and it ended around my waist. I wore this jacket in class 5 rapids on a rafting trip in Costa Rica and it didn't rip once when I fell into the water. It is very durable and kept me reasonably warm in the heavy rain.

Got the Willow- it is more of a true green color, but still very pretty. Jacket is extremely lightweight and flexible. Kinda short for my liking (ends right at my hips), but I like jackets to be a bit long. I'm 5'2", 110 lbs and the XS fits fine- sleeves are good and long. Small is more comfy on me- just depends on how you like the jacket to fit. Haven't tested it in the rain yet.
