I've searched and googled, but I can't settle on an inexpensive (<$20) short sleeve base layer. Just want something to wear under a short sleeve jersey down to 45-50 degrees with the temps generally warming during a ride. The Champion double dry compression shirts are in that range, but does anyone have experience with this brand? I can vouch for plain compression stuff doing little else than stopping loose parts from jiggling - the stuff I've tried doesn't breath too well. I'll spend more if I have to, but $50 for a "technical" T shirt seems pretty silly. I'd rather confine my bicycle spending excess to the search for a perfect saddle.
