Best waterproofs for cycling by a country mile

Excellent idea, miles better than all the other expensive guff available. They do what is required and are tough enough for commuting and long rides. Price is reasonable too.

Quality item.

Good value.

Unexpectedly good

I wore these to work on a very wet day on purpose just to try them out, I was very impressed. Admittedly I’m only commuting on an e bike but I don’t take it too easily on a very hilly ride of 8 miles. No wet in the inside and the foot covers a a really good idea.

Good, At First

These are pretty great, at first. The shoe covers are amazing and the product is good. However, the material is pretty thin and after about 3 months, i have holes at the shoe cover, holes at the back and now a hole where it rubbed the chain ring. Saying that, i am going to buy another pair, as i live commute every day and need a pair that will keep my feet dry.

Very good

Very good trousers easy off and on, Good value

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.
