The Microtherm Stormdown Jacket is part of Eddie Bauer's First Ascent line of mountain wear. This is my go to mid-layer for the coldest of days.
Design: Like most things Eddie Bauer, you are definitely getting quality. Much thought into the design of this insulated long sleeve. The outer woven shell and lining are 100% nylon, the knit shell (armpits) is 95% polyester and 5% spandex, and the insulation is 90% goose down at an 800 fill. One breast pocket and two lower hand pockets offer everything you need for storage. The breast pocket has a port for media and headphones. The stretch fabric in the armpits ensures that your movement is never restricted. This garment is also fairly packable as well.
Weight: Extremely light weigh. You cannot even tell that you have another layer on.
Durability: Not the most durable. This is meant to be worn with a shell or jacket as an outer layer. The fabric is very easy to snag and could tear with ease. Stitching is top notch. I have worn this layer for years without any issues regarding durability.
Style: Fits more into the mountaineering or, dare I say, TGR crowd than here at Newschoolers. Don't worry, your XXL jacket will cover it up if you are worried about that.
Fit: At 6'1" 165 lbs, the large tall fits me perfectly. Most companies do not cater to us tall lanky folk when making pieces like this. Another plus for EB. Fits true to size, obviously if you are tall get the tall fit. Not baggy and not super tight. It is like wearing a pillow.
Waterproofing: NOT WATERPROOF. Definitely plan on wearing a nice technical shell over this if you are in wet weather. Down does not react well to getting wet; it will clump up.
Breathability: Surprisingly, it does breath very well. I have overheated while wearing this, but unzipping helps in those situations. I have gotten to the point of near sweating and this microtherm did let out the warm air quick enough to prevent me from becoming a sweaty mess.
Warmth: This is where the Microtherm Stormdown shines. With 800 fill goose down, you will be as warm as can be. Even in -15 degrees with high gusty winds, other body parts have forced me to go in while my body / torso has always stayed warm enough for the elements. Plus, it does act like a mini cushion for those bails in the park.
If you want the ultimate in warmth, look for something with 800 fill. There are many different options out there, but Eddie Bauer has not let me down.
