Montane Litespeed H2O Jacket - Women's

But the sizing is off. The armpits are very tight - they bind and pinch. I normally wear a US 6 or 8 so ordered up a size. While the torso itself was an "athletic fit", the armpits were way too tight. Bummer there aren't any other larger sizes. I loved the weight and my husband has a Montane jacekt he swears by.

Just wore it for a fifteen mile run in the rain. It did a great job of keeping me dry and is super lightweight and fairly form fitting so very comfortable to run in. It is way cute and a number of co-runners were very jealous (they were wearing garbage bags and way less comfortable).

In a size US10/UK12, this fits my wife, who usually is a size small (4 or 6) in US jackets (backcountry.com, patagonia, stoic, helly hansen, etc), so keep that in mind when ordering -- sizes are way off. I was glad for the advice here to order two sizes up.

On my scale, the jacket weighs 5.5oz (if you add the stuff sack, it goes up another 0.4 oz), way over the advertised specs -- especially because this jacket is the same size as the reference jacket. The difference between 4.0 and 5.5 is huge from a percentage perspective -- the jacket is almost 40% over spec; when you are looking for the lightest possible option, this is a tremendous disappointment.

If we had paid anywhere close to full price, I would have been very disappointed and sent it back. Many of other manufacturers make similar jackets that weigh the same or less.

Hasn't been used in the rain yet, so I'm not sure how it will hold up. On the upside, the colors and fit are better in person than I expected -- looks nice on and the red is a much more pleasant red than the pictures would indicate.

Size runs quite small, which would be good for running or biking, but not for layering when backpacking or working outdoors. Can't say how many sizes I would recommend going up for this, since there were no more to choose from. I imagine an extra size or two up would also make the back way too long.
Pockets would be nice too.
Too bad, because the price is right and its so lightweight.
