Using this product, our team found that the Icebreaker Sleeve Crewe was perfect for any outdoor activity. The fabric is lightweight and comfortable, making it ideal for running or hiking .The black monsoon color combination adds an element of style that can be paired with any bottom wear for the perfect outdoor look. However the sizing runs a bit small so make sure to order one size up for the perfect fit. Overall, a great addition to any men's activewear wardrobe..
