Remember to properly fasten the overshoe’s elastic behind the heel for secure pedalling.
Our 540 and 900 City Cycling Overpants have a specific cut for both men and women.

Unisex cut

- Water-repellent treatment
A fluorine-free chemical wash on the fabric's surface makes water slide right off. This treatment can be reactivated by heat (10 minutes in the tumble drier on a gentle cycle).
- Waterproof construction
A waterproof strip under the seams prevents water getting in.
- Waterproof fabric
A fabric's capacity to prevent water from penetrating it.

Waterproofing

Waterproofing is measured in Schmerbers or mmH2O (the pressure exerted by a water column).
A material with a rating of 10,000 mmH2O (400") can resist 10 m (10 yd) of water.
The bigger the number, the more waterproof the fabric.

Measuring waterproofing

To preserve their waterproofing, we recommend regularly reactivating the fabric's water-repellent property. You can do this every three washes or after a dozen uses in the rain. The overpants’ water-repellent property can be easily reactivated with heat: put them in your dryer for about 15 minutes. After washing, be sure to rinse completely.

How to care for your overpants

You can clip lights behind each leg using the 2 attachment systems.For more freedom of movement, you can use pant clips to tighten the cuffs.

Compatibility with lights and pant clips

Wear your overpants with a waterproof poncho or jacket.

For optimal protection

Hydrophilic coating (RET = 12): Limits condensation inside the garment. To determine a fabric’s breathability, we test its evaporative resistance or RET (based on the ISO 11092 Standard). The lower its resistance, the more the fabric allows perspiration to escape, increasing its breathability.For example: RET < 9 = extremely breathable fabric. 9 < RET < 12 = highly breathable fabric. 12 < RET < 20 = breathable fabric. RET > 20 = slightly or not breathable fabric.

Component breathability

XS / S = 28 cm long x 7 cm across (11 x 2 3/4")
M / L = 29 cm long x 7.5 cm across (11 1/2 x 3")
XL / 2XL = 30 cm long x 8 cm across (12 x 3 1/10")

Tightening Type

A product’s ability to protect against the cold depends on its thermal resistance and breathability. The higher the thermal resistance, the more body heat it retains while you ride.
During intense rides, perspiration on your hands can make them feel cold. We therefore recommend exercising at a moderate intensity in cold weather.

Product warmth

Waterproofness is a fabric’s ability to prevent rainwater from soaking through. 
Water repellency refers to a fabric’s ability to make water bead off its surface without being absorbed. The fabric soaks up little or no moisture, dries more quickly, and remains light. Water repellency also helps keep the outer surface cleaner.
Water repellency is obtained by applying a treatment to the fabric's external surface.
This product is not waterproof!

Water repellent component

Machine wash at 30°C. Synthetic cycle. Use minimal laundry detergent. Do not add fabric softener. Hang to dry in a warm, well-ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.
