Pardon me, but the jacket I received must had been made a year or two earlier than the other reviewer's jacket. I know that WB-400 has a fleece interior, and the jacket I got was about 25 percent WB-400, and Nano-Sphere technology was definitely not on the jacket. I am not sure it was even available to the public at that point in time. Perhaps Mammut redesigned the jacket between the time I got mine and he got his. Maybe mine was last year's model and his this year's...
The previous review is misleading -- the whole jacket is made from Schoeller WB400 with Nanosphere treatment. There is no piece of Shoeller Dynamic anywhere, which is totally different animal. I think this is a very good jacket, with trim fit and nice features -- external pockets located high to not interfere with harness and two internal pockets. What's missing is a drawcord collar -- at least with my neck there is a huge gap, which is not a good thing for a shell, especially a warm one. That's why I returned it in favor of Mammut Laser Jacket (also made from WB400), which has an attached hood that gives even more protection.

The procuct description says Schoeller WB-400. I ordered it and realized that part of the jacket was WB-400, about the top one quarter of the sleeves and some of the body panels. The rest of the jacket is, I believe, another Schoeller product called Dynamic. The WB-400 is a stretchy, abrasion resistant fabric with a very breathable (much more than Gore-Tex) film between it and the fleece on the inside. The Dynamic is just abrasion resistant, stretchy nylon.
I could not figure out what the product would be good for, not enough for colder weather and too much for warmer weather. You'd have to be going full tilt in cold weather for it to be functional, but don't stop or slow down, you'll probably freeze. Get a full WB-440 product for colder and a Dynamic product for warmer, but this mix seems rather useless. I returned it before I even tried to figure out when to use it.
