Small in size
Color: Grey
Very small, picture makes it look much larger than it is. Seemed more appropriate for a cat, and 6 month puppy figured it out in under 1 min. Not very challenging.

Extremely good quality. Soft ... SIZE UP if you want a looser fit. It is not "form fitting, or snug, but no extra. I am 5'5 190# 60 years old. This ... an XL will go to my daughter. I will be getting another 1-2 sizes up. We'll worth it!
