I can't find a loose fitting base layer made out of merino that I enjoy wearing. Admittedly I've enjoyed one two many cervezas and my fair share of donuts, which consequently has resulted in me having a little extra insulation, so putting on base layers makes me feel like a sausage in a casing. I've even tried to order base layers two or three sizes too big (C4E) and still get that skin tight fit around the mid-section. I'm doing my part to lose some weight, so maybe one day I won't feel like a Vienna sausage, but in the meantime, I'd like to find a base layer that fits more like a t-shirt, anyone have any suggestions?
