These shorts are so light weight and comfortable, which is great for long runs. The fabric and construction make it airy and breathable, which is good when running on hot days. The inner lining adds a bit of security. The waist band is wide and high rise, which is helpful, as there is no digging, but the construction of it and the material (basically it seems to be a breathable "leggings" material folded on itself) means that it bunches, or creases while I run (which is the only reason it is 4 stars rather than 5). It could be that it is just due to my shape though and it might work better for others. Nevertgeless these are good and comfortable running shorts and I keep using them for many of my runs.
