I followed the sizing chart which led me to order a "L" but I could barely get it zipped up - I wear a 44 coat and have a 36" waist. The Aion team was very helpful with assisting me in exchanging it for an XL however. From a quality of product standpoint, it appears to be great quality!

The vest is great quality but the sizing is way off
The vest is great quality but the sizing is way off. My husband is a large and the vest was far from closing
Hi there, thank you for your feedback. I’m glad you found the vest to be great quality, and I’m sorry the sizing did not match your expectations for your husband.
Our vests are meant to be a tight and snug fit, so they can feel smaller than expected when first tried on.
I’ve also reached out to you directly so we can understand your experience better and help you further.
Thank you for trying our vest.
