Product Customer Reviews

Had it for 2 years now, still puffy.
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.
After reading reviews on here, I decided to order this jacket in a blue medium. I am so pleased with it, very light, comfortable and looks pretty good on too. Thanks for your honest reviews guys, well done to all, Tommy
Great product does what it says on the tin
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.
Good quality light weight jacket
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.
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.
Lovely Jacket , Great quality
I like this jacket
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
Excellent jacket, great fit, well made.
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.
My second one, they are great! Good value.
good fit, good price,
