I ordered some mid weight base layers and a hat from them. I haven't tried on a hike yet but they seem to be VERY HIGH QUALITY. The mid weight is quite thick and smooth and the fit is excellent. If they're as warm as I expect they'll be and machine wash like the website claims I'd likely have to give this gear a big thumbs up.
A caution on mid-weight base layers (Re the "I hate down..." thread):
Base layers should be the lightest weight that is practical so you can dissipate a maximum amount of heat when needed. Unfortunately, light, mid, and heavy weights are not well defined or consistent across manufacturers. I use light weight polyester base layers, but light-weight Smartwool is too fragile and mid-weight is a better choice. For comparison, I have some 100-weight fleece* long underwear which may have been called mid-weight but is far too hot for hiking. (I use it when lift-served skiing and may carry it as emergency gear.)
* Fleece used to come in three weights: 100, 200, and 300 (grams/sq meter). Now days, all outerwear seems to be ~200 weight.
FWIW, I wash essentially all of my mountaineering clothing (except for waterproof-breathable shells) by hand using ordinary detergent. If I am doing a big load of fleece, I may spin it in the washer to get most of the water out before hanging to dry.
