Our review

Stylish and compact design, suitable for active, year-round use. Good jacket for the price, but may be too lightweight for harsh winter weather.
Pros: Affordability.

Looks sleek – a good option for urban and country walks.

Lightweight enough to be worn in the warmer months.

Wide range of colour choices.
Cons: Waterproof rating not as high as other jackets on test.

Decathlon’s Waterproof Mountain Walking Jacket is a standard year-round option, especially if you looking to save a bit of money. At 538g, it’s light enough to use in spring and summer when bad weather strikes, and can be easily stowed away in your pack when not in use, but the jacket can be worn in the colder months – with a few caveats – particularly if you’re a fast mover on the trail. The simple, stylish design will appeal to urban dwellers, too.


The three-layer construction includes a waterproof membrane, which gives the jacket a good level of protection against the rain – though not as much as some of the other jackets on test. In really heavy downpours for longer than an hour, water begins to seep in around the neck. The hood is minimal in design and close-fitting, adjustable from the front and back with a semi-rigid visor, offering protection from the elements while allowing good movement and visibility. The cuffs can be tighten securely using adjustable straps, and there are drawcords at the jacket hem.

There is elastane in the fabric, which makes the jacket stretchy, meaning you can move quickly, freely and comfortably, and underarm vents offer a chance for quick cooling.

On cold days you’ll need to wear a couple of layers beneath this jacket. It’s quite a close fit so if you usually teeter between two sizes you may want to opt for the larger option.

There are two zipped pockets on the outside of the jacket. These are designed for hands but can also fit an OS Map – though it’s a bit of a squeeze and is difficult to access if you’re wearing a rucksack with a hip-belt. Two small pockets on the inside of the jacket are handy places for storing snacks, GPS devices and phones.

Decathlon Solognac Warm Short Wellies

These wallet-friendly wellies feature a removable fleece inner so warm that wearers can comfortably stand still for half an hour at -12°C, according to Decathlon. They are so well insulated they’d be too warm outside of the coldest months; and minus the inner they’d probably be too big.

The inner is integrated to the boot via a rather flimsy pull-loop; it’s essential for getting the boots on and off, but it soon came away in my hand as I pulled them on. Designed for fishing and frosty walks, these wellies are reasonably light and have decent grip, with soles studded with deep lugs.


They’re only available in black for men, women and children.
