Swimming Jammers are the most popular form of swimwear at the moment. You can spot this type of swimsuit by the fact that they often look a lot like lycra cycling shorts. Swim jammers provide the most coverage of all the styles, from the waist to just above the knee. Usually made from Xtra Life Lycra or PBT, these swimming shorts are good all-rounders.
You can pick up a FINA-approved pair of jammers designed specifically to reduce drag and support muscles for swim racing. Or, at the other end of the scale, you can find long-life chlorine-resistant jammers with fun designs for kids. There's a huge range of men's jammers out there for all your swimming needs.
