Great Lightweight Jacket

  • Familiarity: I've put it through the wringer

Great all around rain jacket. I've put it through the paces without any issues in the rain or wind. It's worked well as a runaround in the rain jacket to fall hiking in and sailing in the NE. The wrist velcro wrist adjustment is a welcome departure from elastic, it's especially helpful when layering. 180lb - 6' - M fit well with room for a mid-layer.

Great rain jacket.

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

I love this jacket, it's roomy enough to add a warm base layer, and the helmet draw cord is great to give better fit with or with out wearing a helmet. This fits perfectly.

Dry in the PNW!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

Purchased this jacked for a two week trip to the PNW. Of course, it saw rain, lots of rain. I stayed dry and comfortable and the pit zips are great for additional ventilation and for when I needed to cool off. I found it to be true to size and I was able to wear a base layer. The hook and loop wrist adjustment for me is necessary. Many other jackets just have elasticized wrists. I am 6 feet tall, 170 lbs, and Medium is right for me.

Nice lightweight jacket. Sized way small

  • Familiarity: I've put it through the wringer
  • Size Bought: XXL

Bought is for spring bike and bc skiing. So far it has been good. I ordered about 1/2 size big so I could layer (XL). That was still too small so I went back for XXL. I am pretty average sized.

Update: If you will be riding in windy rainy or windy sleet conditions use a different jacket, the zipper is not waterproof when the wind is blown in, like on a bike. Otherwise I still like the jacket and it is my goto for AT skiing and biking, just not in extreme weather.
