This jacket works great at keeping the wind out. I wore it this morning under my alpinestars viper air textile jacket and it kept me pretty warm for my hour ride into work. For reference I live at 8600 feet in the Rocky Mountains and travel 50 miles each way to work. I wore this this morning and it was 29 degrees Fahrenheit and I averaged about 70 the whole way to work even hitting about 90 at one point I was never really cold but not exactly warm either but at 29 degrees that's to be expected. The only part of me that got cold was my hands but I don't have insulated gloves at the moment. The fit is great it's snug like it should be to fit under my other jacket and you can't even tell its on. There's no bunching up or uncomfortable seams. I would certainly recommend this jacket for sure. And as always revzilla sent it out in a timely manner as I received it 3 days after I ordered it!

This Jacket is just what I needed. I had been looking for a windproof mid layer to wear over a regular t shirt and underneath my Leather jacket and this is it. It fits great keeps the wind completely out and is very comfortable.

I bought this jacket to pair up with my TZ-1 Reload perforated jacket. In cooler weather riding it really works well blocking the cold air that comes through my leather! I'm 6'1, about 195 and the XL fits me perfectly. The arms are long enough, which is a pretty rare find. My TZ-1 jacket is a 46 US that fits me just right, and the tech jacket fits inside it just fine. I haven't noticed any uncomfortable stitching or anything like that. It's a fairly form fitting jacket, which I think is the desired fit given the nature of the piece. Decent pockets, decent styling, good neck protection from the elements, no uncomfortable zipper rubbing around my chin or neck. It's a good jacket that fits me great, and does its intended job very well. The only minor drawback for me is the little monkey cuff things you can put your thumbs through that come out of the ends of the sleeves are too tight for me and cut off circulation to my thumbs. Other than that, top notch.

i have a perforated gtr plus jacket and it was a great match for that not so warm morning . i was shocked how much wind this shell stopped ! it was 39 this am on the ride to work and i was completely warm with just a tshirt the shell and my jacket . super impressed well worth the money ! super tight fit so if u plan on wearing more than a tshirt under by a size bigger . I'm 6ft 175 with long arms ordered a m and returned for a L . cut of the shell fits good with the cut of a jacket no bunching up so you don't feel like the kid on the Christmas story. so all and all you will be happy with the $$$ spent once you wear it !

This midlayer let's me ride deeper into the winter comfortably. Windblocking, water repellent, keeps body heat in and is not restrictive especially in the arms. As I said, it does everything well and looks good while doing it.
