Rizanee Men Mesh Breathable Multi-Pocket Vest Outdoor Travelers Fly Fishing Photography

Seems good, though even the XXXL is tight, even over just a t-shirt (it would be nice if the clasps at the front could be adjusted just a little). I have my doubts that I could put a sweatshirt or jacket on under it. I haven't used it yet, so we'll see. The pockets look useful; since I'll be using it to carry keys, my phone, and maybe bug spray or a small hex wrench/screw driver set when I ride my recumbent trike, that's a plus. Since I'm losing weight, the tightness should only be an issue at the start; if I weren't, it would be a problem, since I don't want to wear it open and have it flapping around. Just for reference, I normally wear an XL, occasionally an XXL, in t-shirts, sweaters, etc., and probably a Size 48 business suit these days.

Fits perfectly

I am using this for Dog training, to carry treats, toys, keys phone etc
