JUST THE RIGHT WEIGHT Winter running is rough on motivation. We've all been deterred in making that first step because of the cold. Our Italian mid-weight merino wool, with a half zip air flow adjustment, will keep you comfortable throughout the run even when the temps drop and the winds are strong. This can be worn by itself or with layers underneath - from a singlet to a long sleeve - giving this top a wide range of comfortable temperatures depending on what you pair it with. THE LAYER YOU ALWAYS NEED There’s always that one piece you reach for first—the one that’s never in the drawer because it’s always in the wash. The Adirondack Wool Half Zip is built to be that go-to layer, the one you trust when the air is sharp and the miles feel long. At its core is Woolight, a premium Italian blend of extra-fine merino, polyester, and elastane, designed for warmth, breathability, and durability. Merino’s natural insulation keeps you warm while remaining breathable as effort increases. Polyester enhances moisture-wicking and quick-drying performance, while elastane adds flexibility without losing structure. Unlike traditional wool, this blend resists shrinking in the wash, ensuring long-term performance. Soft, odor-resistant, and built to last, this is wool without compromise. Ideal Weather: Cold (25 to 45), Very Cold (Less than 25), Mild (45 to 65), Windy, Rainy Fabric: 49% Polyester / 47% Extra Fine Merino / 4% Elastane Cut: Straight Cut Top "Straight Cut" garments are generally designed for individuals with a more uniform torso, as the garment is generally straight in its construction. Its size bands are commonly described or labeled by other brands as a "men's cut," "unisex cut," or "tailored unisex" though our garments are not slim fit. The size you most expect to be, if reaching for a garment labeled as "men's," would be a helpful starting point. Bakline firmly believes that garments should be described with respect to how they are designed. Anyone, regardless of gender, can be comfortable and perform well in any of our cuts depending on your personal preferences, body shape, size, and style. To better determine your size, we've calibrated a size recommender and provided detailed fit guidance specific to each product. If we have not provided product specific guidance, we have a high level sizing page and you can always contact us via the Live Chat or by emailing Bakline Support for help.
