The addition of a zipper fly to any kind of pants would never hurt and fleece sweatpants with zippers are no exception. But why do so few pairs of sweatpants have a fly that actually opens and closes? Although we like a comfortable pair of sweatpants just as much as the next person, we have never understood why so few manufacturers make sweatpants with a fly that really works. It makes no difference to people whether the joggers or sweatpants have a button fly, zip fly, or Velcro fly closure at the waist. It makes no difference. Simply said, we want something in my sweatpants other than a fly that is sewed closed to serve a more practical purpose. Even more aggravating is the fact that almost no manufacturers indicate in the product description of their joggers or sweatpants whether or not they have a functional fly. This forces prospective buyers to either go through customer reviews or place their orders in the dark. Here are a few brands that produce sweatpants with zipper flies. 
Boden UK-based Boden was formerly known for selling menswear; however, the company is now far more well-known for its extensive collection of brilliantly colored apparel for women. It would suggest that the firm is making an investment in its menswear collection, which now offers a variety of fashionable alternatives for men, including athleisure and activewear, as well as elegant chinos and button-downs. (Boden is another excellent example of a fashion business that practices sustainable manufacturing.) Boden has a long history of producing sweatpants and joggers for men that have a functional fly, but since they change their inventory with each season, you'll need to go over their current assortment of sweats in order to determine what styles are now available. A pair of Boden's Rye Joggers for men are constructed from a fabric that is composed of 87 percent cotton and 13 percent polyester. They are, without a doubt, the most comfortable pair of sweatpants one would own. The joggers include a drawstring and an elastic waistband, in addition to a functional fly opening. 
Even though the Rye joggers are no longer sold online, Boden still sells lightweight joggers that include a zip fly. Mack Weldon Mack Weldon is a menswear apparel brand that specializes in "reinventing men's fundamentals" by providing men with t-shirts, underwear, socks, athleisure, and other types of clothes that are both comfortable and attractive. In addition to being an excellent online destination for men's multicolored socks and striped tagless t-shirts, the firm is particularly skilled in the art of manufacturing work-leisure clothes for guys. Mack Weldon's Sunday Lounge Pants include a zip fly that buttons up in addition to having a fly opening. This is in contrast to some of their sweatshirts and joggers, which do not have fly openings. These trousers include an elastic waist, an inside drawstring, and 100% peached cotton flannel, so not only do they appear fashionable but they also feel quite comfortable.
