Product Customer Reviews

This is so comfortable and lightweight but warm in the wind
Nice product
Was keeping me warm till around 5 degree Celsius
It served me a good purpose in -4 degree. Really with the price.
Water resistant genuine product
This product is sold as windproof along with some warmth but sorry it solves neither of the purpose. Waste of money completely

The Product is absolutely amazing. Its perfectly wind proof and really does keep you warm.
Product quality is top notch, and fitting is also amazing..... material is rugged..
superb
The jacket is an excellent performance product. Can be used in different conditions, chilled weather or a bike rides too. You feel very warm and cosy inside and also feel the re bounce of wind when traveling bat a high speed in temperature less than 10 to 15 degrees. Over all comfortable to wear. Could have a hood it would have been better. But worth it.
Excellent product
Good for riding in Winter and mornings. Not that good for wearing in mid day riding. not breathable, meaning - discomfort will be felt, sweats a lot. For this it could have been a little cheaper.
Good

As compared to this price range this product is not up to the mark and sleeve fitting is also weird for me. i am 5"7 and using small size..but good part is it is good againt winds for north india.

What is softshell?
It is a warm protective jacket that protects you from the wind and a short downpour (about 30 minutes) of light rain or snow. The fabric used is an assembly of 3 materials: a breathable and windproof microporous membrane sandwiched between the water-repellent outer layer and the inner one made from warm, comfortable fleece.
What measures have been put in place to reduce the environmental impact of our softshell jacket?
To reduce our environmental impact, we have put measures in place on several levels: - the outer fabric is made of 100% recycled polyester - the inner fleece uses a clean dyeing process called dope dyed (the yarns are self-dyed) which reduces CO2 emissions by 21% - the patronage has been designed to reduce fabric losses as much as possible, which has made it possible to achieve 90% efficiency.
Thermal comfort and windproof
The wind makes you feel considerably colder. With an outside temperature of 32°F and 12 mph winds, it will feel like the temperature is 14°F. The so-called “windproof” components take away this discomfort by creating a barrier against the wind; they also reduce heat loss extremely efficiently.
What is the breathability level of this softshell?
The main fabric has a windproof membrane with a breathability of 3,009 g/m² per 24 hours (according to the JIS L1099 standard, A2 method).
Functions
2 hand pockets with zipper fastening Inner flap under the front zipper to protect against the wind. Protective stand-up collar Elasticated cuffs Elasticated hem.
Water-repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its ability to make water run off its surface without absorbing it. This prevents the fabric from swelling and keeps it lightweight and warm. The fabric is made water-repellent by treating (PFC-free) its outer surface, however this property may deteriorate with use. We recommend that you restore it after each wash.
Follow the guide! https://www.forclaz.co.uk We recommend that you use the care product to treat and restore water-repellent properties https://www.decathlon.co.uk/p/fabric-waterproofing-liquid-250-ml/_/R-p-308192
