The REI Rain Spout hat fends off passing spring showers and provides summertime shade while your little one puddle-jumps or plays in the sun. Nylon shell features sealed seams at the crown for water resistance; mesh lining and sweat band add soft and dry comfort. Magnets in the brim and crown make it easy to fold the brim up at the sides. Breakaway chin strap is adjustable.
