Hoping to save some money I bought first one, then another, off-brand vests from Amazon and promptly sent both of them back for refunds. They were both size XL, which should have fit me but neither did. Both were bulky and stiff. Both had very heavy batteries. One had a zipper that caught the fabric and got stuck.So I went ahead and ordered an Ororo in size XL. It arrived yesterday. Fits perfectly, fabric is soft and flexible, good zipper, battery is about half the size and weight of the cheaper brands, and unexpectedly it came with a charger (so I can send back the one I bought extra, expecting there to be none.) And it looks nice on me too - not like the bulky other vests that made me look like The Hulk.I'm charging the battery now, but I have the vest on already and it's keeping me warm in my cold, wood-heated house. I'll be testing out the heated features this weekend at a barn hunt trial.From what I'm experiencing with it so far, I'll definitely be keeping this vest.
