A truly waterproof pant

The pants fit well enough to ride a bike without any problem while being comfortable inside. The elastic allows to maintain it well on the shoe to keep the feet dry.

Very impressed.

Tried it out in heavy rain and it worked a treat. Like the extra features like the large opening on the bottom to slide into with ease, the reflective tape, and the in built elastic strap to keep it all together when rolled up. Already recommend it to my cyclists friend and even motorcycle groups.

Great rain pants for cycling.

Have yet to try in the rain. Seem like they will do the job. Love the fact that they cover your shoes, this is a must whin biking in the rain. The fit is a bit on the large size perhaps for movement.

Decent overtrousers

My son cycles to school and puts these over his uniform on wet days. The straps keep the shoe cover part in place and the hi-viz stripes are great for dark mornings.

Keeps me dry in rain

Does what it says on the tin: Protects from rain. Overtrousers are easy to fit and take off without removing your shoes. There is a strap underneath the sole that keeps the shoe cover in place, protecting them from the rain. The overtrousers are lightweight and easy to store.

Dry warm legs. Son yet to receive the trouser, Christmas stocking gift. Sure he will be delighted as he was with his jacket.

Lovvit when it rains.

Thought these waterproofs with shoe protection as well looked too big. But when on were fine. I like a bit of room or they'll be more likely to split.Now look forward to heavy rain as it's fun riding past soaking wet fellow cyclists -sounding my bulb horn and having a giggle.

Additional Product Information


Main fabric

  • 100% Polyester cationic


  • 100% Polyurethane


Unisex cut designed for cyclists. Built-in overshoes to protect shoes in the rain. Remember to properly position the overshoe's elastic behind the heel to ensure a good hold while pedaling. For greater freedom of movement, if you need to tighten the cuffs of your overpants, we recommend using an additional pants clip.


These overpants are waterproof thanks to the durability and coating of their fabric and sealed seams. A fabric's waterproofing is determined by measuring its resistance to the pressure exerted by a water column, measured in mm (test based on ISO 811 standard). Our component is resistant to the pressure from 2,000 mm of water. The finished product is approved in a shower test in the lab, where we recreate the conditions of an average downpour: 60 L water per square meter per hour for 2 hours.

Compatibility with lights

This product has 2 attachment systems on the back of each leg for you to clip lights onto.


Hydrophilic coating (RET = 12): reduces build up of condensation inside clothing. To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower its resistance, the more the fabric lets water vapor produced by the body escape, and the more breathable it is. 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.


Dyeing in the mass is used to dye the fibers during the production of the fabric to reduce the environmental impact of the dyeing. It also reduces water consumption and pollution.



Product testing

This garment has passed a shower test of 60 L water/sqm/hour for 2 hours. This test reproduces the average conditions of a rain shower in the city. The waterproof strips have a life span of 2 years for regular use (around 3 times a week). To keep them in good condition, fully open the rip-tabs at the cuffs of your overpants when putting them on to avoid rubbing against your shoes. Also remember to apply a waterproofing spray after washing.

Storage instructions

Don't pack the product away when it is still wet as condensation may form and cause unpleasant damp odors. Leave your product to fully dry after use before packing it away.

Care instructions

Wash at 86°F. Use liquid detergent Do not use fabric softener Close zippers before machine washing. Do not tumble dry.
