So far so good

Very happy with this jacket

Front pocket

Decent jacket, unfortunately the front pocket zip is very weak, zip broke on my 3rd ride which is disappointing as this was the feature that made me purchase this jacket.

Pretty good, could be a bit better!

Bizaare that you are asked for reviews after a couple of days but here goes. Just wanted a long sleeved top for cycling but Decathalon dont seem to do autumn / winter version, just these more coat style tops, which at circa £50 aren't the cheapest. I cant comment on water proofing yet, but it is a reasonable wind stop and warm enough for autumn especially if you are working. There is a breast pocket which is good for your phone and zipped pockets on the rear, however the traditional cycling pockets are on the side which i think is unusual, however they are so shallow i don't think i would dare put anything in them.

Great Jacket

Got it reduced in the sale. Reckon it'll be perfect in early spring, late autumn (got it in late Feb) , worn with a vest, and most likely good in winter with something more substantial. Fits well, looks good. Great MTB jacket.

MTB jacket

A really good jacket for the money and more happy with its performance

Looks great, runs v small

Tried on in store. It’s a strange size, nice and long at the back but ridiculously short at the front. Need to go up a size too but unwearable for me. Seems well made and practical but looks better in pictures than in real life.

Mtb jacket

Stylish, warm, fitted jacket. Front phone pocket and rear pocket for keys.

Great jacket, great purchase

Great product, sizing was a bit odd but keeps me warm and dry when out on the bike.

Great jacket

This is a great jacket, but more if a shell than a warm jacket. It needs a base layer under it. Then it’s really good

The 4 layers you need to stay warm when mountain biking.

How to stay warm and dry during winter MTB tours We're going to explain the 4-layer technique for the upper body: Start with a layer of underwear. For the second layer, place the straps of the bib over the top. Your anorak will then form and in the event of poor weather, a waterproof jacket will provide the 4th layer. Are you ready? Then get ready for your winter mountain bike tours, and cycle in comfort.

A clever design: cut, seams, materials...

The bib at the rear stretches down to the saddle, protecting you from splashes. The diagonal cut across the shoulders provides greater freedom of movement. The anti-slip waist keeps the jacket fitted close to your body. The foam-backed neck and wrists provide greater comfort and protection. The different fabrics ensure warmth, ventilation, and durability. And the full zipper closure can be opened and closed single-handedly, even with gloves!

No need to carry a hydration backpack!

A bottle holder on the frame is all you need to get going! Thanks to its pockets, this jacket allows you to cycle without carrying anything on your back. - 1 secure, waterproof vertical pocket at the front for your phone, accessible with one hand, even when wearing gloves! - 1 secure rear pocket for your keys, documents, etc... - 1 side pocket for an inner tube and hand pump. - And 2 side pockets for your cereal bars... and empty packets!

How we tested the st 500 jacket... with you!

We surveyed mountain biking clubs in 5 countries as part of the design process for this product. This resulted in 50 hours of interviews and 1000 user questionnaires to try and answer this question: "What do you want from a winter MTB jacket?". Once the prototypes were created, they were tested with users. On the menu: your feedback and your experience to ensure we offer a product that meets your needs.

We are incredibly proud...

... resulting from 18 months of designs, models, prototypes, surveys, tests and feedback with the entire design team. Why? to ensure we provide you with an innovative, accessible, comfortable, clever product that is suitable for your mountain bike touring.

Advice from the design team:

One last tip for before you hit the road (or should that be the trail)? "The most important thing is to be well equipped... or to be well supported!" To avoid any unpleasant surprises and to ensure your mountain bike tour doesn't turn into a long hike on foot, remember to prepare for any snags or technical issues. With a relaxed mind, you'll be able to enjoy yourself even more!
