Membrane vs. Stretch Woven Both softshell jackets aren't totally waterproof since they don't have taped seams to keep water out of the stitched regions. Stretch-woven softshell jackets are more breathable than membrane softshell jackets and are popular for outdoor activities such as jogging or cycling. They're also great options for warm-weather pursuits like hiking or biking. Waterproof softshell jackets are usually made from a nylon/polyester blend with a DWR (durable water repellent) coating. These jackets are ideal for active people who may get wet during outdoor activities such as surfing, kayaking, or canoeing. It's important to choose the right size softshell jacket if you want to be able to move comfortably while keeping out the elements. Try on several styles and sizes before you buy to make sure you get the fit you want.
