Hanes Pullover Hoodie (Red)
Size: Large, Color: Deep Red
​Pros: ​The red color is vibrant and looks great out of the box. ​Initial fit is decent. ​Cons: ​Excessive Shedding: The "fuzz" and inner lining fibers get absolutely everywhere. It sticks to your undershirt, your hair, and even the furniture. It’s a constant annoyance that doesn't seem to stop even after the first wear. ​Color Bleeding: The dye runs significantly. If you aren't extremely careful in the wash, it will ruin anything lighter than it, and you'll notice the vibrancy of the red fading faster than expected. ​Low Durability: Between the shedding and the dye issues, the quality just isn't there for long-term use. ​Final Verdict: I’d give this a 3/5 at best. While it’s an affordable basic, the mess it leaves behind and the hassle of the dye running make it more of a headache than it’s worth. I’d recommend looking for something with a higher-quality fleece lining that won't leave you covered in red lint.

Comfortable!
Size: 12.5 Big Kid, Color: Purple/Turq
My daughter loves these. She’s5. We got the size 12.5 and they fit her well.. a little space between her toes and the tip of the shoe but just the right amount. She says they are comfortable and good for her PE class and playing outside. We got the blue and then I ordered the black cause she loved them so much. They were on a great sale too!
