Good value gillet

This is the cheapest gillet I have - yet it’s warm, is light and packs down really small into my rucksack. It’s not got great water reliance but it withstands a light shower. Great value for money.

Brilliant light body warmer.

Really light weight item. Very warm over a fleece mid layer. Useful zipped pockets take a big wallet and XL sized phone with ease. Folds down to a tiny pack size when the weather warms up.

Excellent quality for the price

Bought size medium and size large for my husband, he was a little disappointed that the large was the better fit; but to be fair he is probably somewhere between the two sizes. This is similar quality to another lightweight gilet I looked at which was double the price. It’s been worn almost every day since Christmas so a great success. I was able to return the other size by post even though I bought in store, very quick and easy process once I’d emailed customer services.

Unbelievably good

I would not usually waste time providing a review but feel compelled to share that this garment is excellent in quality and fit so represents unbelievable value. You can buy this and the jacket version for less than what you would pay for one down jacket alone from the most competitive brands yet it is 100 per cent comparable to them. Also impressive is that it is Responsible Down Certified. Extremely chuffed with it and want to wear it all the time. Btw, I am a slim 5"10 with a 30 inch waist and medium sizes as snugly as if it were fitted (so if you're prone to adding a few pounds over winter you may wish to size up).

Well fitted but quite shiny

I’m 6ft 4, slim and ordered Large. Top quality gilet, comparable with some high end brands in fact. Lengthwise it’s acceptable. Not too short but would have enjoyed another inch or so for complete satisfaction. Chest is to size, but the material (navy) is quite shiny. Doesn’t bother me too much but it didn’t look like that in picture do loses a star.

excellent value

I was ready to spend the money on a RAB until I watched a review on youtube, they compared this to a Mountain Hardwear Ghost Whisperer which is considered the Number 1 ...both this one and the Whisperer dont have a breast pocket or any internal pockets which is why I didnt give it a 5*, the warmth fit and quality are very good for the price. this was my first time ordering from these people and the service and speed was 5* .. I will shop here again ... NB: im normally a xl but ordered a xxl .... perhaps I am getting bigger :(

Good gilet but sized a bit tight

This is a good gilet, especially considering the price, but the size is on the small size. A tight fit helps the heat stay close to the body.

Sleeveless gilet

Warm. Fits great and dual purpose, sport/ walking and casual.

Great price for a good quality product.

Really pleased with this. Sensible pockets and fit, I'm slim but sized up to XL (L in other brands), didn't need to in the end. It's a good length where other gilets are quite short. Warm for the weight and robust fabric, I've worn it climbing under my harness. Only downside - the material is a bit shiny but appears matte in the images... not the end of the world but I prefer matte.

A good lightweight top

Very reasonably priced its that light weight you don't even feel you've got it on. And is very good when the Chill is in the air.

smallish on the fit, and the zip feels cheap and catches on the internal baffle easily - so go a size bigger than you normally wear - but comfortable and warm

Perfect for Autumn

I bought this as I needed something that would keep me warm during walks and singletrack cycling, but was not too bulky or interfered with my riding and it is perfect. Warm and easy to use...just waiting for winter to see if it is usable, but if not can be easily stored away until spring.

Got two and love them - orange and black just wish you would do nicer colours for women

Why wear a down gilet?

A gilet helps to keep the body warm: it protects the chest, neck and kidneys from the cold, as these areas a especially sensitive to chills.It is sleeveless so it saves weight in your backpack, provides even more breathability during exercise and excellent comfort of movement when worn under a jacket.Worn underneath the MT100 down jacket, it can provide 6°C extra warmth when compared to a down jacket worn without the gilet.

The advantages of a duck down and feather filling

The filling power of down has 3 advantages for mountain sports:- Thermal insulation thanks to the air trapped in the down and feathers.- Ultra-lightweight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack.- Ultra-compressible.

How to measure the fill power of a down and feather wadding?

The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. It is expressed in CUIN (cubic inches). So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation. For this sleeveless down jacket, padded with 85% down and 15% feathers, the fill power is guaranteed to be 800 CUIN or higher (European standard).

What is rds certification?

RDS or “Responsible Down Standard” is a worldwide certification issued by an independent organisation to volunteer brands. This standard enables us to guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only feathers from geese and ducks raised for their meat and slaughtered before down and feathers are collected.

How to care for a down and feather gilet?

The down jacket can be worn throughout the winter and will certainly need to be washed. But the less you wash it, the more it will retain its thermal insulation and water repellency.Summary:1/Machine wash with a detergent suitable for down or technical garments, at 30°, with 2 or 3 tennis balls. Gentle spin between 800 and 1000 rpm.2/ tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until it is completely dry.

Water-repellent property of component (not to be confused with waterproofing)

The water repellent property of a fabric is its ability to make water run off its surface without absorbing it. This prevents the fabric from swelling, and keeps it lightweight and warm. The fabric of this down jacket is water repellent, however, we recommend that you wear a waterproof jacket over it in the rain. The fabric is made water-repellent by treating (PFC-free) its outer surface, however this property may deteriorate with use.We recommend that you restore it after each wash.

How do i reactivate the waterproofing properties?

Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric. This renews the fabric’s water repellent properties and optimises its performance throughout the lifespan of your garment.

A snag? here's how you can repair your sleeveless down jacket

A tear on a padded jacket can happen when trekking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the feathers from escaping.Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded jacket using a heat-bonded patch.
