Fabric Composition: 8-ounce, 50/50 cotton/poly: This means the fabric is a blend of 50% cotton and 50% polyester. It's a common blend for comfort and durability. 60/40 cotton/poly (Heather Sports): A variation of the blend, where the fabric has 60% cotton and 40% polyester, commonly used for heathered (or melange) fabrics that have a slightly more textured, multi-tonal appearance. Construction: Double-needle stitching at waistband and cuffs: This is a reinforcement stitch that adds durability to areas that experience a lot of wear and stress. 1x1 rib knit collar, cuffs, and waistband with spandex: This detail ensures that these areas (collar, cuffs, and waistband) stretch and fit snugly but retain their shape over time, thanks to the addition of spandex. Visibility Compliance: Safety Green compliant with ANSI/ISEA 107: This refers to a bright fluorescent green color that meets the safety standards for high-visibility apparel, often used in work environments where visibility is critical (e.g., construction sites). Labeling: Recycled, high-performing black tear-away label: The garment features a sustainable, tear-away label that is easily removed without damaging the fabric. This ensures comfort and a more polished look for the wearer. Transitioning Labels: The manufacturer is moving to the new recycled label design, so some products in your order might have the old label, and others the new version. This just means there may be a mix of the older and newer labels in the same batch.
