More colours please

I've worn these Kola pants for years. Working in hot countries they really can eliminate chafe. However they used to be available in green, blue and purple. It seems now that the elastic in the waistband parts at the seam. Not as good as they were.

Come up small

Had to exchange

So comforable I bought more pairs

I needed something to wear under my trunks to retain modesty when taking part in active water sports. I bought one pair in store in June 2017. I found them so comfortable that I started to wear them daily as boxer shorts. When I went back to Decathlon to purchase more pairs they were out of stock. I ordered four more pairs online. Two pairs arrived within 5 days and were of the same quality as the first pair. I had to wait several weeks for the second two pairs to arrive. I found that these were of slightly different material than the first three pairs (possibly from a different supplier). The first three pairs had been a very soft microfiber but the latter two pairs were very slightly less soft and flexible They also sat lower on my hips so were not exactly the same fit as the first three pairs. Otherwise they are of good quality and very comfortable.

Better than I thought.

Felt & fitted like a 2nd skin . We're great under shorts I had cut the net out of , for being uncomfortable . They had a lot of use over two weeks and I can't fault them.

Good product

I wear these boxers under my wetsuit similar to wearing a rash vest. The only negative is that in my opinion the size of the boxers is not aligned with normal clothing garments. I.e I had to buy 2 sizes bigger than normal boxers

What is the olaian brand?

OLAIAN, DECATHLON'S SURFING BRAND Based in Hendaye, in South West France, OLAIAN is Decathlon's surfing and bodyboarding brand. In our offices at the water's edge, we can design a pair of boardshorts and then on the same day go surfing and test them to check that they stay in place in the waves, are comfortable and durable.

Sandproof component

The component of these boxers allows the evacuation of grains of sand, thanks to its special mesh. This contributes to the non-irritant effect of these under-shorts.
