Patagonia Baby Capilene Daily Long Sleeve Crew

Long sleeves in hot weather? This shirt makes sun protection practical, thanks to featherweight polyester (35 percent recycled, with 6 percent Spandex) that provides UPF 50+ sun protection. “Not only does it cut down on greasy sunscreen applications, but it does a great job of protecting my four year old’s arms from sharp twigs and underbrush,” one parent says. (Kid’s take: “It’s my favorite.”) It also dries within minutes, so it can pull double-duty as a rash guard for pool and beach wear.
