Running shorts with liner, or built-in underwear, help reduce chafing and sweating on your run. The liners are usually made of a thin, loose-knit fabric that may look like mesh and are more breathable than regular underwear to keep you cooler on your run. The liners are usually short and cannot be seen when you wear your running shorts. Some liners are even designed to be worn without underwear and are similar in style to compression shorts or boxer briefs.
Liners are important for runners to avoid chafing as they run because the friction of skin against skin is the leading cause of chafing. Runners can also develop chafing on the inside of their legs, especially near the groin area. The lining in running shorts absorbs sweat and pulls it away from the legs, helping to limit this friction between the leg and the liner or the leg and the outer running shorts.
Most loose-fitting running shorts come with a liner or built-in underwear to help prevent chafing on long runs and over longer distances. The liners are typically made from a fabric blend that includes polyester, elastane, spandex, or nylon. These fabrics are great for sports clothing because they are breathable, dry quickly, and help to cool you down when you’re running. The linings in running shorts are also shorter than the shorts themselves and can be pulled up or down when you need to take off your running shoes or re-enter the water.
Some runners prefer to wear running shorts that do not have a liner so they can wear their own comfortable underwear and still feel comfortable on their run. These styles tend to be lighter in weight and can be worn multiple times before needing to be washed. However, they can become chilly faster in cold weather and can lack the support of a liner which some runners require.
Many running shorts have pockets for your phone, keys, and other items. Some have side and back zip pockets for easy access to your belongings while you’re running. Other styles have a drop-in pocket in the waistband to allow you to store your running essentials without removing your shorts. Some running shorts have a wider waistband for a flattering silhouette and a more secure fit while others have a thinner waistband for a minimalist style.
There are some running shorts that do not have a lining and you can find them easily on the market. These shorts can be very lightweight for summer runs and are ideal for warmer weather or when you’re looking to layer up for the cooler months. Some of these shorts have mesh on the side splits for added ventilation while you’re running. They’re also available in different lengths and can be found in both men’s and women’s sizes. Some of these shorts are also available in a variety of colors and can be purchased from online retailers such as Amazon. These shorts are a great option for anyone who wants to save money but doesn’t want to compromise on comfort.
