I gave the Stratam Jacket to my husband for Christmas and he loves it.
He is 5’9” and weighs 175 and the jacket fits great and he looks very nice wearing the jacket. We live in the northern half of Minnesota and this jacket works well as a mid-layer under a wind and water replant jacket, or light puff. It just depends on activity level and can be all that is needed. The Stratam packs efficiently and can easily be stuffed in back pack. With all that, the jacket will take him into restaurants with upfront style. Now I need one for myself.

Warm midlayer, high quality, just perfect

I've used it everyday!

Well made light jacket. Worn over a base layer it keeps you warm and is breathable for when you work up a sweat. If you use a wind/water proof shell it will keep you warm in cold temperatures. The jacket is thin enough to layer a coat or whatever you may need over it. I find it very versatile. Since I have had it only had it a couple of months and have not worn it in extremely cold conditions I am not able to say how it will hold up to years of use. I would recommend to anyone looking for a quality light mid-layer. I did have an issue with the first jacket I received but a message to their customer service and I had a new jacket within a week.

(No relation to Stu above)Left off a review of this until I had worn it for a season and forgot to do so, so its now a few years old. Fits well. I am 42 in chest average build and a medium fits exactly. Its very expensive but very well made. I use it for Himalayan trekking up to 5000+ metres and it does the job. The air temperature is a few degrees above freezing in bright sunlight but drops badly in cloud or high winds. I bought it for a main layer over a t shirt. I find it too hot on its own in sunlight and use it mainly as a throw-on when I stop or as an underlayer with something windproof or watertight in bad weather.

The thumb loops are great, the equivalent of light mittens which allow gloveless work on packs, tents etc and really add to the feeling of warmth. They do tear easily though – mine have been patched several times although I do wear rings which probably doesnt help. The rest of it has worn extremely well. The full front zip allows good ventilation and the neck fits snugly- if you roll the hood up to act as a neck scarf, you wont need a Buff or simliar. The hood itself is useful, I usually dont need anything warmer than that unless its snowing.

A small chest pocket would improve it – lipsalve, sunscreen tend to fall out of the side pockets. My main gripe is the side panels which are more permeable than the front and back. I suppose the idea is ventilation for sweaty exercise, especically running. , but this doesn’t work on cold dry trekking. I can sweat buckets up there but find that the side panels end up being cold spots – big ones - when the sun goes in and the wind springs up, the front panels are pretty wind proof so if the whole thing was made like that it would improve it for me.

So I revert to old tech fleece-lined Pertex which works better in wind at ½ the price.

But as a layer for stops and/or evening in the tent or lodge its great. I automatically goes into the pack for summer and winter.
