I'm shooting for a layered system this year and just ordered the uninsulated shell Jacket and Bibs from Klim in Tall sizes but the dealer said they do not have any tall sizes available in the base and mid layers. Looking around and I might be able to find Carhart wool/rayon base bottom and tops but I'm not finding squat for decent Mid layer. Anyone got any advise for decent quality mid layers in tall sizes up to 2XLT?
