I am wearing these as an all-season base layer for motorcycle riding and light touring. I wear them underneath a protective jacket and pants.
First, they are made of a soft fabric that is not slick feeling and does not generate static cling etc.
Second, they are cut even, fold easily and neatly, and fit appropriately. The shirt is neither too tight nor too loose. Pants also fit correctly and come with a fly which is not the case with some base layers.
Third, they seem to function as advertised, whereby, they are not as hot as other products in the heat but feel warm in the cooler temps. The fabric washes up well and dries quickly. This also translates to wicking moisture in hot temps and not feeling wet, clingy and clammy.
