The sleeve lengths vary, and they’re suitable for different water sports. That said, our line was primarily designed to meet the specific needs of surfers. 
Choose your rash guard based on the duration of your surf session: 1 hour, 2 hours, or 3 hours.

How to choose your rash guard (Part 1)

1 hour: Occasional practice. Choose either a loose fit (easy to put on, comfortable when dry) or a tight fit (comfortable when wet). Look for a loop system so you can fasten the rash guard to your shorts.
2 hours: Regular practice. A rash guard with a drawstring and seamless underarm panels will improve fit and comfort in the water.
3 hours: Intensive practice. A style with added warmth will let you stay out longer.

UV protection

UPF (ultraviolet protection factor) is an international standard that measures  the proportion of UV rays a fabric lets through to your skin.A UPF of 50+ means that the fabric blocks at least 98% of UVB rays and 95% of UVA rays.

What does UPF 50+ mean?

This UV-resistant T-shirt limits rubbing and chafing against surfboards and bodyboards. It can also be used under a diving suit to limit rubbing, particularly around the neck and armpits. Seamless panels under the arms reduce irritation caused by paddling movements. Our tests show that chafing is significantly reduced after a 2-hour session.

This UV-resistant rash guard has a drawstring at the hips to keep it firmly in place. You can also attach it to the drawstring on your boardshorts to prevent it from riding up while you surf.

Support and stability in waves

This rash guard is recommended for use in water temperatures of 22°C and up. Air temperature may affect this recommendation.
Our thermal models are made of fleece, neoprene, or both. We recommend choosing a model made with neoprene if you’ll be out in conditions where the wind exceeds 15 km/h.

Warmth and wind

Our UV T-shirts meet the needs of the most demanding surfers. They’re also compatible with many other water sports, including kitesurfing, windsurfing, wakeboarding, water skiing, and stand-up paddle boarding.

Suitable for multiple water sports

This top is UV-resistant, but it doesn’t provide total sun protection. Consider other factors like reflections (off water, sand, etc.), temperature, and time of day. Wearing this top is just one part of staying safe in the sun. You should also wear sunglasses and a hat or cap, apply sunscreen regularly, and drink plenty of water.

How to choose a wetsuit Part 1

The second thing to consider is the length of your sessions. Our 100 models are suitable for sessions of up to 1 hour. For 1-2 hours, opt for a 500 wetsuit; for 2-3 hours, go for a 900. Wetsuits with a higher model number are warmer, more watertight, and better at reducing irritation and fatigue The same is true for the 900 models, compared with the 500 models.
Note: The 900 models are easier to put on.

How to choose a wetsuit Part 2

To get the most out of your wetsuit, it’s important to choose the right size. A surfing wetsuit should fit snugly and have no visible folds. It’s normal for the suit to feel too tight when dry; this discomfort will disappear once you’re in the water. If you choose a suit that's too big, creases will form and irritation will appear.

Choosing a size

This OLAIAN 500 shorty is made from neoprene for improved comfort during use.
The synthetic lining provides added wear resistance.
Neoprene thickness: 1.5 mm.
The neoprene is made of an elastomer foam with insulating properties.
We test and guarantee the quality of our neoprene materials. 

Materials

The neck is designed to limit irritation. If you have sensitive skin, consider wearing a UV-resistant top under the wetsuit to reduce rubbing and chafing. To prevent chafing during longer outings, we recommend applying petroleum jelly around your neck and underarms. Make sure the flap is always inside the wetsuit to limit the risk of irritation with the zipper and the neck.

Neck

Our zips and fastenings are lab-tested for guaranteed durability and resistance to salt water. The zip is at the back of the wetsuit for greater comfort when lying down to paddle.

Fasteners

There is a key pocket under the zip flap.

Key pocket

Seamless panels under the arms reduce irritation caused by paddling movements.

Anti-chafing design

When you’re in the water, more than half your body heat is lost through your extremities (feet, hands, head). To stay warm, consider these accessories:

- in water (>17°C) => low cut neoprene socks.
- Cold water (12°C–17°C): High-cut booties and gloves.
- Cold water (7°C-12°C): High boots, gloves, hood, and hooded top.

Boardshort Length

Boardshorts is a term used to designate this type of swimwear used in the world of surfing and water sports.
Practical and comfortable, they are suitable for both men and women.
This type of swimwear was created in the 1950s for surfing. In more recent years, they have become a popular style of swim shorts.
The name comes from their use in aquatic board sports, like surfing.

What are boardshorts?

100 range: Occasional surfing and water sports. 
Short cut.
Elastic waistband: Suitable for all body shapes. Drawstring for stability in the waves.
Inner mesh: protects from chafing.
Quick drying.

500/900 range: Regular surfing.
Various long cuts, protection from chafing.
Flat waistband: A more secure fit in the waves during duck dives and wipeouts. 
Stretch fabric for freedom of movement.

Boardshorts design

Size guide on product file.
The boardshorts in the 100 range are available in sizes S to 2XL.
The 500 and 900 ranges are available in sizes S, S-M, M, L, XL and XL-2XL.
Your body shape can influence your choice of size.
We always recommend trying on swimwear before purchase. Fasten your shorts and gradually pull them downwards. If they are easy to pull down, it means they are too big and you could be in for a few surprises once you’re in the water surrounded by waves!

How to choose the right size of boardshorts

When surfing, whether from duck diving or wiping out, having to readjust boardshorts that have fallen down is far from convenient... This makes choosing the right waistband essential. Opt for an elastic or semi-elastic waistband with a drawstring or a flat waistband for a more secure fit.

Wave resistance

In aquatic board sports like surfing, it’s particularly important to have maximum range of motion so your boardshorts should have an ample amount of stretch. The boardshorts 500 are made from a material with four-way stretch.

It is surely the most important criteria.  It is common for the boardshorts or its seams to chafe. Our boardshorts are designed specifically to limit chafing, a common issue for surfers.
In addition, they benefit from a central strip that moves the seams away from the usual friction zones, which has the effect of significantly limiting the occurrence of irritation.

Waterlogged boardshorts can easily become caked with sand. For this reason, choose a "stretch" component which evacuates water more quickly from the swim shorts.

Quick-drying

Boardshorts length comes down to personal preference. However, you should be aware that the shorter your shorts are, the greater the freedom of movement. The average size M is 19 inches long (48 cm).

Length

These boardshorts have a flat waistband that helps keep them up when you fall into the water or have to duck under a wave. This waistband style is also more comfortable when you lie down on the board to paddle.

Waistband

These boardshorts feature a zipped side pocket.

Pockets

During the summer, when the weather’s hot but the water’s cool, surfers tend to stay out on the water longer without changing their equipment. This increases the risk of sunburn.
Did you know? The water’s surface reflects 10%–15% of UV rays, leaving 40%–95% to penetrate to a depth of up to 25 cm. This is why boardshorts combined with sun protection (UV top, etc.) are becoming the essential equipment for surfing in water >25°.

Surfing Swimsuits, Bikinis & Shorts

Shaped to optimize arm rotation while paddling. Stretch seams.

This shorty wetsuit is designed for surfing in warm water, for sessions lasting up to 1 hour.

The first factor to consider when choosing a surfing wetsuit is the water temperature. Water temperature varies depending on the location and time of year. Keep these guidelines in mind: Warm = above 20°C. Temperate = 17°C–22°C. Cold = 12°C–17°C. Very cold = 7°C–12°C. Visit seatemperature.org to check sea temperatures around the world.

The second thing to consider is the length of your sessions. Our 100 models are suitable for sessions of up to 1 hour. For 1–2 hours, opt for a 500 wetsuit; for 2–3 hours, go for a 900. Wetsuits with a higher model number are warmer, more watertight, and better at reducing irritation and fatigue. The same is true for the 900 models, compared with the 500 models.
Note: The 900 models are easier to put on.

To get the most out of your wetsuit, it’s important to choose the right size. A surfing wetsuit should fit snugly and have no visible folds. It’s normal for the suit to feel too tight when dry; this discomfort will disappear once you’re in the water. A diving suit that’s too big can have folds that chafe and allow water to seep in, reducing thermal comfort.

This shorty is made of 1.5-mm neoprene for guaranteed comfort in the water.
The synthetic lining provides added wear resistance.
Neoprene thickness: 2 mm.
The neoprene is made of an elastomer foam with insulating properties.
We test and guarantee the quality of our neoprene materials. 

When you’re in the water, more than half your body heat is lost through your extremities (feet, hands, head). To stay warm, consider these accessories:
- Warm to temperate water (> 17°C): Low-cut neoprene booties.
- Cold water (12°C–17°C): High-cut booties and gloves.
- Very cold water (7°C–12°C): High booties (boots), gloves, balaclava and balaclava top.

In order to prolong the life of your wetsuit, Decathlon is committed to ensuring that all Neoprene wetsuits are repairable and in perfect condition after repair!

How to choose your boardshorts according to the waistband

When surfing, whether it’s due to duck diving or a wipeout, it’s not easy to retrieve and reposition boardshorts that have fallen down while paddling at the same time...
Choosing the right waistband for surfing becomes essential in this case.
Go for an elastic or semi-elastic waistband with a drawstring that goes all the way round the waist. 
The BS 100 15-inch boardshorts have a fully elastic waistband with drawstring.

Wave resistance 
100 range

This has got to be the most important criterion when choosing swim shorts.
It’s not uncommon for a swimsuit or boardshorts to rub and irritate the skin.
Our boardshorts are designed, both in terms of the shapes offered and the assembly methods, to minimise chafing as much as possible during your time in the water. 
On the 100 range of our swim shorts, the inner mesh or briefs help to reduce the occurrence of this unpleasant phenomenon.
