For all the benefits of a space age design, it's still apparent that keeping it simple also works. The men's less-is-more Burton Southside Pant meets all the requirements without appearing too technical. That said, our exclusive thermo-regulating Living Lining offers stealth performance for the ultimate in adaptable warmth and consistent comfort. Whether you choose the slim fit or the tailored mid fit, there is still room to layer and move freely. All styles feature Test-I-Cool venting along with a handful of rider-inspired standard features.
