After receiving some Woolly ultralight boxer briefs as a birthday gift and loving them, I decided to try the t-shirt as well. Now I want to replace all my synthetic base layers with Woolly! They are super soft, not a hint of "wool itch", and even have a bit of an upscale look with a slight sheen finish as a bonus.
I found these tees to be quite stink resistant. As an experiment, I decided to try going without a shower for a week and wearing the same Woolly tee every day without washing it (anything for science!). While I can't say I the tee was entirely odor free at the end of the week, it was way way less smelly and more comfortable than any synthetic layer I've tried would be after a single day. The Woolly shirt also rinses out easily and drys quickly, comparable to the washing and drying synthetics.
