A good puffy jacket is a winter staple, and having one that you can run in is even better. That’s why Saucony made the Oyster Puff Jacket. This puffer coat has a recycled polyester shell that is wind and water resistant to shield you from Jack Frost. The recycled polyester insulation is compressible and gives you that super soft down-like feeling. The insulation material is made of .5% ground oyster shells for warmth, and the sleeves are brushed inside for extra coziness without restricting mobility. Plus, the sleeves and hems are finished with elastic v-folds to keep the elements out, and there are zippered hand pockets to store essentials. Stay warm in the Saucony Boulder Oyster Puff Jacket whether you are taking a stroll downtown or hiking through the mountains.
