No colour options

It’s very disappointing to see other colours are not available for this exact jacket. I’ve been wishing to replace my older same jacket as it has been more than 4 years. But only one colour option on the website for over a year. Please please add more colour options for this jacket

Best jacket ever

wearing it almost daily from last 1 year and it is so perfect.

Best clothing purchase I've ever made

I bought this coat to keep me warm when camping after a full day of cycling. I have always previously suffered from the cold but this jacket has completely changed that. It fits perfectly, even with layers underneath and allows plenty of movement. The two way zip stops any bunching and loss of heat when sitting down and the sleeves do not ride up my wrists as in many other jackets. I'm not keen on the colour (coral) but that was all that was in stock when I needed to make my purchase and I'd forgo colour for the warmth provided here any day.

Lovely and warm

I love this jacket, love its unique colour and it fits lovely.. Nice deep pockets and is so cosy. Only gave it 4 stars as the sleeve has ripped slightly after rubbing against my backpack straps within 2 weeks of wear.. To be fair I've sewn it and it seems to be holding well.. Its not put me off thou, I intend buying another one the same on my next visit..

the jacket is great but the pouch was missing

The jacket is incredible. Does what it says. Have worn it in 2 degrees with a single layer and also in -17 degrees with triple layering. It protects from harsh winds and is really warm. Have used it in skiing as well and the cap is designed to block all wind. Ordered two sizes up for easy layering. It has strings to tighten up from below for tighter fit. It’s incredibly lightweight and easy to carry in person and in the rucksack. I was disappointed i did not get the pouch but its still is really compact and can be fit into its own cap.

Good product

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling scheme. To get more information:

Weight of down lining

- XXS = 3.7 oz - XS = 3.9 oz - S = 4.1 oz - M = 4.3 oz - L 4.5 oz



Storage instructions

To ensure down inflates when jacket is not being used, store it unpacked in a dry and well-ventilated place.
