Thanks for that link. The difference seems to be that the Minus33 stuff tends to be machine washable and dry-able. AdamDZ recently wrote that all wool can be cleaned by machine as long as it's very gentle, but the manufacturer's approval gives it some reassurance. Other than that, that product seems like a good buy for those that like those colors and the V-neck design. It's available with more colors and sizes at lower prices at Amazon.com.
