The ACG Wildsee quarter zip was the perfect product for me to try. I live in Michigan where we truly see every type of environment weither if be rain, snow, or sun and this ACG quarter zip held up in every environment imaginable. I ran with this top on in the rain and it held up incredibly well! I consider myself an avid fitness enthusiast. I train in the gym and outdoors and this quarter zip held up so well! I did training indoors and outdoors and found that this top did well in every environment imaginable. I’m a huge fan of ACG gear and this top made my training sessions perfect! The Wildsee top held up and absorbed my sweat with no issues even while doing some training on the beach with the sun being strong. I felt that it helped enhance my exercise when I trained. I didn’t need to change to another top. ACG gear never fails to impress me. I can count on it to never fail me and hold up incredibly well despite whatever conditions I put the clothing through. If you feel that you need a quality top that will hold up this ACG Wildsee top is the product for you to try.
