Black Friday: swimming jammers
You're knocking out the lengths, you're getting ready for a competition, or you just want a swimsuit that stays put: the jammer is for you. Its long, fitted cut holds in place with every turn.
Compare the models from the Black Friday, then filter by brand and size.
Why the jammer is essential for training
The jammer goes down to the knee or almost. It supports the thighs, minimizes unnecessary movements and handles repeated sessions better than shorter cuts. On this page, you’ll find models from the Black Friday, training versions with more technical cuts.
What matters when choosing
The most important thing is the fit. A jammer that's too loose loses its purpose, while one that's too tight restricts breathing in the pelvis. Look at the material: a chlorine-resistant fibre maintains its support for longer, which is important if you swim often.
Three names to compare for jammers
adidas, Speedo and Arena are featured on this page. adidas offers sporty cuts with a simple design, Speedo remains a well-known name in pools, and Arena is popular with regular swimmers. Use the Brand filter to compare two or three options in the list.
Other cuts to try
If the jammer is too long for you, switch to the swimming boxer, which is shorter. For a minimal cut, check out the swim briefs. The accessories then complement the outfit.

A jammer for what ambition
For club sessions or race preparation, the jammer is the most common choice. It stays in place during turns and glides, and it resists wear well. For a casual swim, a more flexible model will suffice.
Maintaining your jammer to make it last
Chlorine and heat damage the fibres. Rinse the jammer after every session, gently wring it out without twisting, and let it dry in the shade. Alternating between two jammers during the week also extends their life, as the fabric regains its shape between uses.
A fit that needs checking on trial
A well-chosen jammer should fit snugly without squeezing. The leg openings shouldn’t roll up, and the waistband shouldn't leave marks. If you’re unsure between two sizes, check the reviews on the product page and the brand's size guide.
Jammers and training accessories
A jammer pairs well with well-fitted goggles, a cap, and a pull buoy for arm sets. If you’re preparing for a competition, try your jammer several times before the big day to ensure the fit doesn’t hinder your turns.
