Soft microfleece fabric: This pullover is crafted from 100% polyester microfleece, providing superior softness and gentle warmth without adding bulk. Microfleece is known for its lightweight feel and excellent heat retention, making it ideal for active boys who need to stay comfortable and cozy during chilly days, both indoors and outdoors. 1/2 zip in contrast color: The front features a convenient half-zip design that makes dressing easy and allows for quick temperature regulation. The zipper comes in a contrasting color, adding a modern, sporty style element to the pullover. Kids can zip it up for warmth or leave it partially open for a relaxed look and added breathability. Contrast binding on cuffs: The sleeves are finished with contrast-colored binding at the cuffs, ensuring a secure fit and preventing cold air from getting in. This detail not only adds a pop of vibrant color but also reinforces the cuff edges, giving the pullover extra durability to withstand everyday wear and activities. Contrast inner collar facing: Inside the collar, a layer of contrasting fabric provides both a stylish touch and additional comfort. This design element helps prevent irritation around the neck and also elevates the overall look of the pullover, making it stand out whether zipped up or worn open for a layered effect. Warm and lightweight: Despite its exceptional warmth, the microfleece material remains incredibly lightweight, so the pullover won’t weigh your child down. It's perfect as a cozy stand-alone piece in mild weather or as a layering essential under jackets in the colder months. The fabric’s breathability ensures comfort throughout all kinds of activities.
