Great wetsuit top.

A great all rounder. Bought initially to wear in the pool while teaching long hours in winter. But will wear at the beach as well for extra warmth and sun protection. Great budget friendly top.

Good value for money.

I have been searching for a rashi for some time but the lack of variety and price of major brands available were not to my liking. I purchased the Decathlon top and have been using is regularly. Very happy with the product as it is good quality and exactly what I was looking for. I like the colour/design and the tight fit.

Just what I wanted

I already have one of these and am very happy with it. Need another one as my second wetsuit top has finally worn out. I teach swimming and it is perfect to wear underneath my uniform rash vest to keep out the cold. Teaching more than one shift a day it is important to have dry items to put on before the second shift that is why I need 2. Easy to wear, stays warm and very economical.

Does not have neoprene arms or shoulders

Nice top bought for my husband, easy to put on with front zip, snug fit, we went up a size and it's fine but unfortunately it's not clear from the description that the arms and shoulders are not neoprene, they are just lycra and it's loose round the neck so will let water in so is not what I expected.

Tight yet comfortable

Feels tight before it gets wet then feels comfortable in the water.

Sizes are WAY off!

I'm a fairly average sized bloke. If I was buying a t-shirt or a casual shirt or a jumper, I would tend to buy it in size L because I prefer a loose fit. I bought this in L, and couldn't even get the zipper to meet at the front! L is probably the equivalent of XS or even XXS for most garments. Apart from this, the quality is actually pretty good. I'm going to order another one - but this time I think I'm going to go for XXL or even XXXL!


Good value

How does wearing a top help when snorkeling?

Even in water at 86°F, you will end up feeling cold! With a snorkeling top, you can snorkel for longer. The neoprene foam keeps you warm, while the other components protect you against the sun, without limiting your movements in the water. Choose a top for longer and more comfortable excursions!
