Yup, good deals on the stoic baselayers. However, I find just as many deals, even better, on Gear Trade sold by Backcountry and you get free shipping. Many times, I don't buy stuff on steep and cheap just because of the shipping.
Also, by buying gently used gear, it's environmentally responsible.
But, that being said, SAC's deals on the Stoic baselayers is awesome. I really like their alpine merino blends, more durable than straight merino, and dries faster but still stays funk free.
