Nice sweatshirt
Color: White, Size: Small
Really happy with this sweatshirt. The material is soft, warm, and has a nice thickness without feeling bulky—perfect for crisp fall days and layering in winter. The quilted texture and mock neck give it a more polished, upscale look than a regular sweatshirt. Fits true to size, and the color is vibrant and unique. I like the quarter-snap buttons and chest pocket for a little extra style and function. Easy to dress up or down with jeans or boots, and works great for everyday wear or going out. Definitely a solid addition to a fall/winter wardrobe.

Buy it!!! Do not skip on this sweater
Color: Dark Grey, Size: XX-Large
I bought this for my husband to wear if he needed something nicer in the cold weather . But i have wore it more than him because how amazing it is. First off the material is such great quality, it is hard to explain that its thick/ dense but not thick.. the sweater is thin, light and wonderful yet feels thick good quality. It did not shrink when washed, fits wonderfully and color has stayed strong as well. It looks high quality and is an amazing value for the price. No one would know it was not name brand. Do not skip on this sweater.
