As a retired Army (Infantry) NCO, I have paid my dues when it comes to suffering at the whims of Ma Nature's elements in almost every climate imaginable.....literally. Therefore, I especially appreciate "good kit", as our British cousins refer to outdoors and/or tactical equipment. Beretta really did a good job with this shirt (much too lightweight to be referred to as a jacket), and should consider completely abandoning that rattling, loose-fitting, hunk of iron called a pistol, and stick to clothing.....the clothes are actually worth having, but I digress. This microfleece shirt is lightweight, water resistant, well-made, and very heat retentive. I really, really, like this shirt!!! I will probably buy two more...but, BEWARE it is sized VERY SMALL, so order TWO sizes larger, no lie, G.I. I normally wear size L (6'1" 185 lbs), tight as a man's M, sent it back for a XXL and it is a perfect fit. I hate to disparage the garment, but honesty demands accuracy - Order up two sizes and enjoy the finest microfleece shirt I've come across yet. Enjoy, hope this review helps you!
