Ah, Spring. We love it and we hate it mostly on account of the fact that there's nothing more discomforting than embarking upon a warm trail run, only to break through a cold front unexpectedly. So when all else fails, layer strategically like a cake of many flavors with the Icebreaker Women's Ellipse Vest. Crafted with critically placed MerinoLoft panels, this vest offers paramount performance and covert warmth with its moisture wicking and body temperature regulating merino wool jersey while the women specific design keeps you warm in all the places you lose heat easily. A full length zipper, gasket like collar, and zippered hand pockets further make this piece a trail side no brainer.
