The Patagonia Better Sweater 1/2-Zip Pullover's cut keeps warmth locked in across the chest and shoulders, while the half-zip gives just enough venting when the trail pitches up. The pocket flap is woven from NetPlus nylon faille sourced from reclaimed fishing nets, and the body fleece is dyed with a low-impact process. Both details reduce the environmental footprint of the piece without affecting how it layers or wears across a full day outside. What Our Gearhead(R) Experts Are Saying:"I reach for this on chilly mornings before the day warms up. The half-zip lets me dial the temperature without pulling the whole thing off."
