Very stylish color and cut, and functional

Had it for 2 years now, still puffy.

superb - amazingly xcomfortable and warm

I use this when i run into work as it packs away into the right front pocket so I have a proper jacket when I get to work. I've been on walks in the dales and its like wearing a sleeping bag its that comfortable.

Warm and light

This jacket did a great job of keeping me warm at belay ice climbing on Ben Nevis. It's superlight. I dropped one star just because the pocket zips don't run smooth and are harder to use than they should be, especially with gloves on.

Excellent jacket no regrets

Very happy with the jacket. Was hesitant at first as I did not know of Simond or their quality. Glad I went with this one. Really warm. Incredibly light and packs down to a tiny size. Find myself wearing it all the time. Quality is really good and seems like it will last a long time, zippers, material all excellent.

Great jacket

warm and comfortable. Its light, fits well and is made well. A lot of jacket for the price. Would be nice to be able to tighten the hood a little but its made to be worn over a helmet. I have a variety of Simond jackets and I am very pleased with the quality and design of them.

Wore this to the Brecon Beacons on the weekend and it performed magnificently. Used at 5 am when I woke a little chilly. Very comfortable and well made by Simond

Great product, very poor online shopping experienc

Top quality, super warm and light, great price, can't fault the product. The online shopping experience however was tortuous, the worst I've ever experienced. Decathlon say they're "trying to adapt" their online shop but they've had a year to adapt and are embarrassingly far behind their competitors. Up your online game, Decathlon.
