The biggest difference in the variety of baggy cycling shorts is the thickness and quality of the chamois pad or crotch liner. The chamois padding is sewn into a liner inside the baggy outer short. It is real important that the liner material be as stretchy and light as possible so that it is cool to wear in the heat of summer when you are most likely to be outside using the garment. The location of the pockets is important to many people as well. Some people view their legs as engines and don't want anything moving while cycling. Other people want lots of pockets with zippers so they can carry everything they need accessible within a quick zip. Most road shorts do not have pockets, so if you need pockets you may want to consider a baggy bike short. The fit of a baggy short is important because we all have a preference as to where on our waist we want to the short to wear. Some people want a shorter inseam for coolness and air. Some want a longer inseam for protection from sun, briar bushes and branches. Either way, a good stretch elastic waist with a drawstring is essential in any pair of baggies. Lastly, if you get caught outside after dark, a bit of reflective on the left side that alerts automobiles that you are riding is important to add visibility.
