2XL

I started using it this week and what a difference. I wear a traditional concealed vest and this keeps me noticeably cooler in the heat. The difference was immediately noticeable as I stood in the hot Texas sun several times this week so far. It adds a bit of bulk under my shirt but it is still comfortable to wear and fits as it should. I imagine that if you have a large belly it may not fit but if you have an average build you’ll be fine.

I recently purchased this product, and I am absolutely thrilled with my choice! It exceeds my expectations in every way, showcasing stunning design and exceptional quality. From the moment I started using it, I knew I had made the right decision.I have no regrets about this purchase at all! It has proven to be worth every penny, and I appreciate the value it provides. I will definitely recommend it to friends and family who are looking for a reliable and beautiful product. You won't be disappointed!

First day wearing this product in 100 degree weather and it it’s doing its job-keeping me cool under full tactical black vest

It's awesome to get some airflow beneath my vest and not feel like I'm shrink-wrapped. The product does it's job, it does it well, and I wear it every shift under my vest.The product did run a little large so I had to exchange for a size down. The original version didn't allow you to adjust the distance from back to front (the straps that go over your shoulders) so it didn't always sit as I'd have liked. The second one I bought (so I could have a spare and launder it more-frequently), did have adjustable shoulder straps which made fit much nicer—the material also felt better but that could just be because it was new. It does shift around a bit so I will have to adjust it every so often, mildly irritating. I wish they made one I could just hook (like Velcro) into the vest so I only had to put on one thing instead of two.Overall, I recommend this to anyone who wears a vest and I have.

My friend got the 221B ($125) and I got this one. I got the better value. This makes wearing body armor so much more bearable. It seems well made and I expect a long service life. I've had it for 3 weeks. Summer is underway and this is money well spent.

After wearing a few days. It does not like to sit under my outer carrier. I am a motors guys and when the vest is in place great air flow, but after a while of movement it rides up and moves to a side and no more air.Needs velcro or tie down spots. But other than that great product.

Work’s and I see the difference!

Doesn't fit right regardless of measurements. It slides around and is just a pain to use. Complete waste of money! Honestly can't tell if it helps any. The struggle with my carrier sliding around angers me so much I want to burn this thing with the flames of a dog at large call gone wrong!
