Recommended additional product
Forclaz Rain overtrousers protect the lower half of your body and provide a complete and effective rain protection system for your mountain hikes. Care products: spray or liquid water repellent treatment in the washing machine. To renew the fabric's water repellent properties and optimise performance throughout the lifespan of your garment.
Waterproof component
We measure a fabric's resistance to water pressure, expressed as a water column of mm (based on the ISO 811 standard). The higher the water pressure withstood, the more waterproof the fabric. Components scoring 2000 mm can resist the pressure from 2000 mm of water (which is equivalent to a rain shower lasting one hour).
Waterproof garment
NOVADRY® technology: this garment has been subjected to a shower test using 100 litres of water/sqm/hour for 3 hours. This test reproduces the conditions of a violent storm in the mountains. Please visit for more information.
Component breathability
To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more water vapour generated by physical activity evaporates, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 9
In addition to breathable fabrics, Quechua develops technical solutions (zips, ventilation, mesh, etc.) to improve the overall ventilation of its trekking jackets and overtrousers (Forclaz, Bionnassay and Helium lines). These ventilation systems allow you to regulate the temperature inside the garment and also to facilitate the transfer of perspiration generated by the body during physical effort.
Water repellent component
A fabric is water repellent when it allows water slide over its surface without seeping in. This prevents the fabric from swelling, and keeps it lightweight, breathable and warm. Water repellent property is achieved by treating the fabric's exterior. This treatment must be renewed throughout the garment's lifespan (recommended after each wash). Water repellent treatment products are available in our stores. All Quechua waterproof jackets have received a water repellent treatment
A score for comparing products' environmental impact

Worth my money
Used for 2 to 8 weeks
Bought this for my Everest Base Camp trek as my triclimate jacket is really heavy duty. It isn't suitable to wear on the trail unless it is freaking cold at really high altitude. So this worn over a light thermal really served the purpose. The actual jacket is more bright than how it looks here. Before I started to train for this trek had put on medicine induced weight. Although bought one size larger, the fit was very tight. After losing 6 kilograms the jacket fitted perfectly. So it was actually a sensible decision to buy large size when the chart indicated that medium would fit me.
Great colour, quality and fit.
Actual size wouldn't fit.
Best £18 I've ever spent...
Used for 2 to 8 weeks
I bought this jacket in store to take to a festival a few weeks ago after the weather predictions for the first 2 days got worse and worse. It is the BEST £18 I have ever spent. It kept me dry through 2 hours of queueing in heavy rain, then trudging through the campsites and pitching the tents in miserable conditions. Everything else I owned was soaked but when I took this jacket off the hoodie I had on underneath was completely dry. It then kept me dry through constant drizzle the next day, and the material seems to have a hydrophobic coating and dries off really quickly once you're out of the rain. I did not expect it to be this good for the price I paid!

I'm 5ft 2" and a size 10 and would say the medium I have is snug, so it may be advisable to go a size above what you think you may need? But otherwise I was really impressed! (I also have this jacket in 2 shades of turquoise rather than yellow, but I'm certain its the same one)
WATERPROOF, nice colour, comfortable...
sizes come up a bit small?
Amazing jacket
Jacket is very comfortable and totally waterproof. It looks fantastic.
Forclaz 100 Rain Women's Jacket
Used for 2 to 8 weeks
Bought 3 of these and on a recent walk up scafell pike all 3 performed really well. It didn't stop raining the whole day with torrential rain for a long time and not a drop of water got through. Even in August there was sleet at the summit but the jackets all kept out the rain and wind and retained heat. I've paid many times this price and had much worse performance. At this price even if you only get a few trips out of them you've still got an absolute bargain
Excellent jacket
Pockets not big enough for a map
