Assembly Type

Position

Getting your bottle out of the cage can sometimes be tricky (for example, with full-suspension mountain bikes or small frames, or when bikepacking). This cage lets you slide your bottle in from the side. 
What's more, it can be mounted for left- or right-hand access.

Why choose a bottle cage with side access?

Protection Area

Tightening Type

A product's ability to offer protection from the cold. It depends on the material's thermal resistance and how much air can pass through it. The higher its thermal resistance, the more the product retains the heat produced by the body while cycling.

Product warmth

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). 
The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is. 
For example: RET < 9 = extremely breathable fabric

Machine wash at 30°C. Synthetic cycle. Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.

Cap Type

All of our "FastFlow" bottles use the SureSnap® valve, the best on the market. This valve controls the flow of water effectively and precisely. When you press down, water squirts out of the mouthpiece.
Plus, the anti-leak mouthpiece can stay open while riding without water dripping onto your bike's frame.

SureSnap® valve

The mouthpiece is 100% watertight in closed position. Use this position for mixing the isotonic drink in the bottle or for carrying it in a bag.
Once on your bike, leave it open. The SureSnap® valve prevent leaks. Drink quickly and safely!

How to use the FastFlow valve

There’s nothing worse than a plasticky taste or smell in a water bottle. But this is the case for most cycling water bottles. 
We tested numerous plastics before finding just the right one, which is supple and has a neutral taste and smell. When blind tested against bottles from other leading brands, ours were the most neutral-tasting.

No more plasticky smell or taste.

Clean the water bottle thoroughly after each use. If you use isotonic drinks, rinse all parts of the bottle, cap, and mouthpiece to make sure there is no liquid remaining inside. Use liquid detergent and a long brush to clean the bottom of the bottle. 
Dry well and store with the cap off. Otherwise, mould could develop in the bottle.
Do not put in the dishwasher (particularly above 70°C).

How to care for your water bottle

Care Tips

The trisuit material dries quickly so you don’t stay wet while you cycle.

Quick drying

1 mesh pocket at the back and 2 thermoformed pockets on the side of the thighs.

Hot melt tape offers more technicality (elasticity) to the trisuit.

Freedom of movement

Less thread seams and more hot melt tape to reduce chafing.

Reduced chafing

The fully covered back and shoulders protect against the sun.

The trisuit is an iconic accessory for triathletes and a staple for triathlons.
- For swimming, its fabric is similar to that of a swimsuit.
- For cycling, its fine, soft skin adapts to your body shape and improves sitting comfort. The trisuit acts like cycling shorts, to be worn without underwear.
- For running, its fine gel skin is almost unnoticeable: you can run lightly.
All you have to focus on is crossing the finish line!

The trisuit = A 3-in-1 product

The lightweight component of this trisuit allows super-fast drying during your swimming/cycling transitions so you don't stay wet while you cycle. And yes, you can swim with your trisuit on under your neoprene suit to save time during this transition!
This trisuit also has mesh areas which wick away perspiration where sweating is most profuse on your body: under your arms and along your spine.

Stay dry!

- This trisuit has thermoformed elastic at the arms and thighs, so doesn’t move during use or when putting on a neoprene suit for the swimming leg.
- The full-length zipper opens like a gilet and allows you ventilation during the race. It also makes toilet stops a lot easier!
- The top of the trisuit is made of very lightweight material for more comfort and quick drying. The “shorts” part offers very good support.

The small details that change everything!

To get to the finish line of a short-distance triathlon (3 to 6 hours of exertion), you need to eat! This trisuit has two thermoformed pockets on the thighs: you won’t feel them as they are seamless and zip-free, plus the products they hold are under tension and don’t move. 
There are also two net pockets at your lower back. In total with these four pockets, you can carry 10 bars and/or gels for refuelling!

Designed to carry nutrition

None! It’s the same type of triathlon outfit, a 3-in-1 suit: you pick the preferred term.Not to be confused with a neoprene wetsuit that provides buoyancy and insulation for the swim.

Trisuit, triathlon suit, triathlon trisuit... are there differences?

It depends on the water temperature!
The neoprene suit provides buoyancy, an asset for the swim leg. Good to know: The French Triathlon Federation forbids isothermal swimsuits when the water temperature is above 24°C, and requires them when the temperature goes below 16°C. Between 16 and 24°C, it’s up to you.

Should I use an additional suit to swim?

Boardshort Length

Boardshorts is a term used to designate this type of swimwear used in the world of surfing and watersports. 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 “boardshorts” comes from their use in water sports using a board, such as 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–XXL.
The 500 and 900 ranges are available in US sizes S–XL. Your body shape influences your choice of size.
We always recommend trying on swimwear before purchase. Fasten your shorts and gradually pull them downwards. If they pull down easily, they’re too big and you could be in for a few surprises once in wavy water! 

Choosing the right boardshorts size 

Elastic Waistband
Fits the boardshorts to different body shapes.
Semi-elasticated Waistband 
Provides a secure fit and adjustability for everyone.
Flat Waistband 
Ensures the boardshorts stay in place in the waves during duck dives and wipeouts.
Anatomic Design Waistband 
Combines the benefits of the elasticated waistband (adjustability to different body shapes) and the flat waistband (stability in the waves). 

Choosing your boardshorts by the waistband 

Shorter cuts (14–17 in) give you freedom of movement and allow you to do a wide range of water sports, including surfing (for occasional sessions of less than 1 hour). Longer cuts (17–20 in) reduce irritation from the board or wax on the thighs, and at the top of the knees when paddling. Therefore, these cuts are better suited to regular or even intensive surfing. 

Choosing boardshorts by length 

Whether it’s due to duck diving or a wipeout, retrieving and repositioning boardshorts that have fallen down isn’t easy while paddling at the same time...
Choosing the right waistband for surfing is essential to avoid such mishaps.
Choose a flat waistband for a more secure fit. 
The BS 500 has a flat, anti-slip drawstring that stays securely tied throughout your surfing or any other water sports session. 

Wave resistance 
500 range 

Surely the most important criterion. It is common for other boardshorts or their seams to chafe. Our boardshorts are designed specifically to limit chafing, a common issue for surfers.
In addition, the boardshorts 500 benefit from a central strip that moves the seams away from the usual friction zones, thus significantly limits irritation.

Reduced chafing 
500 range 

In surfing, bodyboarding, and bodysurfing, the legs are very much in demand, so boardshorts must not restrict motion and  should have an ample amount of stretch. These boardshorts 500 are made with a four-way stretch material. 

Freedom of movement 
500 range 

It’s really uncomfortable to feel sand trapped in your still soaking wet boardshorts, or worse still, to have the shorts themselves sticking to your skin. To avoid this and to maximize comfort when wearing your wet boardshorts, we recommend choosing swim shorts made with a synthetic fibre fabric, such as this model. Water drains away faster and the swimsuit dries quickly, keeping chafing at bay.

How to adjust your MH 500 Hiking Backpack

This hiking backpack is water-repellent, but not waterproof. It can withstand light rain, but not severe storms! We recommend that you add our 20-40 L rain cover, sold separately, to keep your belongings dry in case of rain.

A waterproof backpack?

Your bag deserves the best care! Opt for gentle hand cleaning: warm water and soap. Gently brush in contact areas. Rinse well, then dry in the shade. Avoid the sun and radiators to preserve its water-repellency. Between two adventures, give it a rest in a dry place.

How do you clean the backpack?

Over time, certain parts can break or become worn. To help with repairs, we make the most common parts easy to replace.

 
Don’t throw your backpack away, get it repaired!
