Product Customer Reviews

Wouldn't purchase again
Having previously made my first purchase from Decathlon online, this time I was lucky to go in and try them on. Buying a size up seems to be the safest bet.

I was looking for a swim swear which was higher than normal but still as slip, and that's it... The NABAIJI B-Strong Men's Swim Briefs Swimming Trunks it's comfortable when you swim, resistant if you seat on rocks and it gets dry fast.
Bought a size bigger than the one stated in the 'check my size' selection after keying in my hip size in inches. Thought that it will be abit loose but to my horror, it was so tight and small when I wore it at home. It was very uncomfortable. The size chart should be revised to prevent other consumers from buying the wrong size like me.

Chất lượng tốt
sản phẩm tốt
The sizing was confusing. I ordered a size larger than my usual (36 instead of 34) and it fits well (but only just)
Vše v pořádku
Doporučuji.
Pěkné barvy
Ein guter Kauf, günstig
Badehose hat eine super Qualität. Sie sitzt sehr gut, fällt jedoch bei mir zumindest etwas klein aus, trocknet schnell und ist für Schwimmer, die regelmäßig Trainer sehr gut geeignet. Dazu noch ein cooler Hingucker im Schwimmbad.

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
Lining
- 100% Polyamide
Style
BRIEFS – side height 5.3". First and foremost, a swimsuit should be comfortable. It should enable you to move with ease. That is why it is important to choose the cut of your swimwear carefully. Bandeau-style swim briefs have a trendy cut that provides good support and plenty of freedom of movement.
Material
100% polyester Our engineers have developed a polyester-based textile and replaced the spandex fibers with PBT fibers. These give it sufficient elasticity to ensure user comfort while protecting it against the damaging effects of chlorine. This PBT thread - is quick-drying. - only loses 3 to 4% resistance throughout its lifespan. - UV-resistant: even the brightest colors will retain their colorfastness.
Aquaresist technology
Products bearing the AQUARESIST label are guaranteed to deliver resistance to chlorine throughout their lifespan. They will maintain their elasticity, and are UV-resistant. For these reasons, they are recommended for regular or intensive pool use.
Use
Swimwear intended for regular use.
