It's a good size apron, and it seems to be of good quality, but the snap closure is useless. I got an XL. The size chart said it would have a two-snap closure. It only has a single snap. Every time I crouch down, bend over, or really move at all, the snap immediately comes undone. It essentially serves no function. If the buckle belt wasn't there it would just fall off all the time. I'm going to have to head to the craft store to look for an add-on solution. Maybe some velcro or a hook-and-eye backup would have helped. I know there's also heavier duty snaps out there that don't come apart so easily. Would have been 5 stars except for the ineffective snap closure.

I am very pleased with this apron! I use it for all types of training. Works great for tracking when I lay a track with several articles. Fits bait bag, articles, clips, etc very nicely! Plenty of room in back for her favorite reward toys. Lanyard for e collar transmitter can be looped to belt easily also so I don't lose it.
When consider sizing, I recommend sizing UP and consider the clothing you wear under apron and how high you prefer the apron to ride. I keep the apron lower near top of hips and not at my waist so I needed proper sizing up to accommodate jackets and having the apron lower.

Excellent fit. Just have your tape measure to check your measurement and then order your size.
