Very versatile, the women's merino wool Icebreaker Nature Long Sleeve Haven Scoop is a sleek, natural, high performance warm to cold weather base layer top. Icebreaker Merino wool has ultra fine fibers so it feels soft and won't itch, and it resists static electricity build up so it won't cling. The lightweight material is perfect for keeping New Zealand high mountain sheep comfortable and happy, insulating to warm them in the winter, and breathing and wicking to cool them in the summer. Merino wool works like this for you too. Icebreaker merino wool resists odor naturally so you can wear it for days or even weeks without washing û and when you do get to it, it's easy care: machine wash cool and line dry. The Icebreaker Nature Long Sleeve Haven Scoop is a soft, sleek, stylish base layer top with comfortable flatlock stitching, feminine prints, and a flattering scoop neck, plus it offers sun protection (UPF 50+) when you wear it by itself.
