Frequently Asked Questions (FAQs)

1. Do jammers help swimming?

Both trunks and jammers present a good option for amateur and seasoned swimmers. Trunks are typically for less competitive swimming, or can be used as 'drag shorts' to increase resistance in the water for a harder workout.

2. Do you wear anything under a jammer?

In general, you should never have to wear any underwear under your swimsuit. If it is a one piece, you don't need to wear a bra or panties. If it is swim trunks, swim shorts or swim briefs, you usually shouldn't wear underwear underneath those either.

3. How do I choose a swim jammer?

There are some key things to look for when picking out the best swim jammer: 🔑 Fabric: Most training jammers, unlike the Lycra-based racing jammers, are made of long-lasting polyester. The trade-off is that they do cause a little more drag, but they are far cheaper and will last much longer.

4. Why are swimming trunks called jammers?

This created controversy and led to FINA, in 2009, placing restrictions on the material and the amount of the swimmer's body that can be covered. FINA stated that male swimsuits must not extend below the knee or above the waist. This style of suit is called a Jammer.
