I've had my sentinel jacket for about five years. I bought this jacket in college because the wind chill on the campus at Texas Tech is brutal. Turns out this jacket got more than it bargained for. This jacket has been through a year and a half of being stuffed in a backpack for sudden rain or dust storms. It's been through a surprise 18 inch snowfall that shut down Albuquerque, NM. It's been my main jacket to protect from windblown rain and downpours in Dallas, TX, and most recently, it's been mountain climbing in January. We went to the top of Texas on Guadalupe Peak, and even though I brought a bigger jacket, I never needed it. We went through a foot and a half of snow on the north face (haha) of the mountain , 25 mph winds through the canyons and 55 degree and sunshine at the peak. My heavy jacket was stuffed in my backpack the whole time. . This is literally the best jacket I have ever bought. It's only drawback is that it is not completely waterproof. It is very water resistant, but after a heavy downpour, you'll get some dampness on the shoulders. I'll definitely be buying another one soon... not because this one isn't still good, but because it is.
