I got several TENCEL™ Lite Boxers, a SilverTech™ Boxers 2-pack, the SilverTech™ T-Shirt, and the recycled cashmere gloves-beanie-scarf-set.
The boxers are fine, though I am worried they won't last more than two years. The quality seems to be on par with, say, Calvin Klein's, nothing special. The TENCEL™ ones in black are starting to bleach out after several washes. Additionally, the t-shirt lost shape after some months. It got really bad after a year or so. It looks ridiculous now. On another note, I can't tell whether SilverTech™ is just marketing or actually working. The gloves, beanie and scarf, on the other hand, seem to be high quality. [Edit: a little over a year after buying the gloves, the material dissolved on the tip of both thumbs, leaving holes.]
Finally, the customer support was super helpful: One of the boxers had a manufacturing error and I got a gift card without any hassle.
Overall, the garments are overpriced and the brand cannot do justice to its mission of sustainability if their clothes don't last longer.
