Nice looking and soft
Special Size Type: Full Zip, Size: XX-Large, Color: Slate Grey
Soft fabric and great color (grayish purplish/bluish). Pants fit nicely, but I may have been able to size down just for how high I can pull them up and them slipping down. On the other hand, I wish the jacket was bigger. It fits probably like it’s supposed to but you can definitely see every lump on my stomach. I will wear it unzipped. The material is medium weight, very stretchy, and nice. I do think it will probably pill- it just seems like things I’ve had that do. I won’t dry it. I’m 5’4” and weigh 195.

Wonderful!
Special Size Type: Quarter Zip, Size: Small, Color: Taupe
Wonderful soft fabric. Not too thick, not too thin - just right! Love the taupe color. I usually wear a small, but needed to size up to medium for the shoulders to have a bit more room to move when I run.
