The sweater that started it all for MerSea. As a MERSEA staple and one of our first designs, our Catalina Sweater is truly a year-round hero to be worn on its own, or among layers. With the MERSEA signature split sides, our Catalina Sweater also features three delicate pockets, a perfectly situated crewneck, and a billowy, oversized fit. One Size. Made by our partners in Ecuador, this piece is a timeless way to stay comfortable.
