Nabaiji - Men's swin short

3 words to describe - stylist, functional and comfortable. Material is elastic but still feels durable.

Hi Chuan Chee,

Thank you for shopping with us and we are glad to hear that you enjoyed the product :)

That is what Decathlon aims to do: offering technical products with an affordable price point. This model is a new model for 2020, with the redesigned "NABAIJI" logo too. We will definitely feedback to the brand team that this model is welcomed by many users, like yourself. We have a slightly longer jammer that you may consider too: Men swimming jammer. They serve the same purpose as this current model, just that the length is longer.

Thank you for your feedback once again and we hope to hear from you soon!

Very good right from material, fitting, looks.

Great enough length in the leg not to cause accidents when chilling after a swim and really comfortable

Worth the money

Good for swimming/training

I bought these for a change from the jammers I wear and they are probably more suitable for lounging around on the beach than regular training but I don’t regret buying them as they will be used.

good product

fits good and better than other product

The best swim shorts I have ever had!

I bought these as I needed a larger size at the time, they are still as comfortable as when I used these for the first time. They also wash well and despite being used minimum once a week, they still retained their original colour. Definitely would purchase another one of these when the time comes in the future!

Hello Tan,

Thank you for taking time to give us a review on the (8361333) - BLACK YELLOW ALLFREK 500 MEN’S LONG SWIMMING BOXER SHORTS.

Glad that you find the bottoms comfortable during your swims. These bottoms are designed for intermediate swimmers who would like to be agile, and also have some freedom with their movements. They also provide good coverage to the mid-thighs, thanks to its excellent chlorine resistance material, which provides UV protection and elasticity throughout its lifetime. If you swim regularly or would like to join other swimmers on their swims, do join our Decathlon Swimming Club on Facebook and be alerted of any events held for swimming activities.

Thank you for your feedback, which is always appreciated! We are always happy to hear about our products doing its intended purpose. Thanks for having Decathlon along with you on your swims, and have a nice day ahead! :)

Stay healthy, by being sporty!

Additional Product Information


Main fabric

  • 100% Polyester cationic

Main lining

  • 100% Polyamide


LONG SHORTS - length 12.6", with good mid-thigh coverage LONG SHORTS are ideal for those who prefer a style with more coverage than regular swim shorts. A swimsuit should primarily favor comfort. It should enable you to move with ease. That's why it is important to choose the cut of your swimwear carefully.


Our engineers have developed a Polyester-based textile and replaced the spandex fibers with PBT fibers that give it sufficient elasticity to ensure user comfort while protecting it against the damaging effects of chlorine. This PBT thread offers the following additional advantages - quick-drying. - only loses 3 to 4% resistance throughout its lifespan. - Even the brightest of colors will retain their colorfastness.

Aquaresist technology

Products bearing the AQUARESIST label are guaranteed to deliver chlorine-resistance throughout their lifespan. They will maintain their elasticity and are UV-resistant. For these reasons, they are recommended for regular or intensive pool use.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. Website: Explanatory video:



Product testing

The products labeled with AQUARESIST certification are tested under repeated cyclical loading in a pool of chlorinated water for 240 hours. No deterioration of elastic strength was observed throughout the test. Unlike a standard swimming product, the product remains intact.

Storage instructions

Store the swimwear in a dry place.
