Unfit for purpose

I wore this in the Nevis range in winter conditions with light wind and rain. The jacket is not waterproof. I aas left cold and wet.

Beware of Simond sizing

This review relates to sizing, not the quality of the product which is generally very good for the price. Almost every item of Simond clothing I have ordered has had to be returned and exchanged for a different size. And there is no consistency; sometimes too big, sometimes too small. This particular item was ordered in a medium (based on another jacket already purchased). It was like wearing a tarp. I'm 171cm. Ordered the small, as a replacement and this is too short across the back - it is hunched up to my armpits and the sleeves rise above the wrists when arms are raised (useless for climbing). Yet the stomach area is baggy and the length is like wearing a short skirt.


Thanks for taking the time to review our Alpinism Light Jacket. Obviously the sizing and fit of a waterproof jacket are very important for waterproofing, freedom of movement and comfort, so your feedback is very valuable and will be passed on the product development team.

I'm sorry that you were disappointed with this purchase and thanks again for your review,

Not worth the money

Had this jacket for less than six months and in no way would I consider it waterproof nor breathable. I called the shop and was told I needed to nikwax it every four weeks including a retreatment to ensure it stays waterproof - it was never waterproof from the beginning and no different after a retreatment of it... did I mention it was less than six months old??

Can't wash after it get dirty

Really bad, after one use in the woods it get dirty of mesh and mud and I could wash it even tried two times. Really disappointed.

Hello Pawel Pieklo,

I'm sorry that the Men's Light Mountaineering Jacket did not meet you expectations. Would you be able give me more detail as to how you tried to wash the jacket and what the results were?

Jackets made for mountaineering are best washed with special liquids such as Nikwax Tech Wash which can be found here:
You would then need to reproof using a similar product to revitalise the breathability and waterproofing:

This method would give you the best results.

Hope this helps

Best quality and great price

Mountaineering light jacket.

Comfy. Found jacket to be lacking in breathability, got damp on inside from not too heavy perspiration. Could be better.

Hood not fit for purpose

This is a great attempt at a quality lightweight jacket. Unfortunately the hood doesn’t stand up to any significant level of wind. The goggles that grip the cords for tightening loosen off and you have to keep adjusting them as wind bellows in the hood! Also the hem with the cord on the front blocks your vision if your not wearing a helmet. Smaller hem at front of hood and a more effective lock on the cords would sort the problem and this would be an awesome jacket for the price! Will have to return.

Hello Niall,

Thank you for reviewing the Men's Mountaineering Light Jacket. 

I am sorry to hear that Men's Mountaineering Light Jacket did not meet your expectations in regards to the hood design. The hood is designed to be compatible with a helmet which may account for some of the issues you have encountered. I have passed on your feedback directly to the Brand.

Kind Regards

Voděodolná není

Bundu mam 3 roky, ale není každodenne nošená. Sedí hezky a nosim ji rád. Proti větru je to dobrá ochrana, ale co se vody týká, snese jen mrholení. Mirný déšť a za půl hodiny jste mokří. Kapuce je velmi otravná, pokud nemáte helmu.

Krásně barevná "goráčovka"

Bundu ve velikosti pánské S nosí 14-ti letý syn, vysoký 164cm, velmi štíhlý. Velikost odpovídá-S je na štíhlé hubeňoury. Je výborně zpracovaná, do kapucy se opravdu vejde helma (lyžařská i lezecká), bude dobře fungovat jako zimní skialpová bunda, v létě i v zimě oceňujeme signální barvy. Příjemná je nízká hmotnost, dobře dostupné kapsy, když má člověk batoh a neskutečná je ta cena. Velká spokojenost

Skvela membranovka

Dlouho jsem hledal lehkou membranovou bundu jako treti vrstvu. Pak jsem narazil na toto. S prihlednutim na cenu jsem dosti vahal ale nakonec jsem zkusil. Lehounka membranovka (xl), povedene zipy, vychytavky, neskutecna prodysnost (na membranovou bundu). Puvodne jsem mel vyhlidnutou konkurenci v hodnote okolo 9tis ale tohle me uchvatilo! Rozhodne doporucuji!


Die Jacke macht einen guten Eindruck und ist auch leicht stretchig, aber mir passt sie im Bereich Hals/Schultern überhaupt nicht. Das Führt dazu, dass sie im Hals unangenehm drückt/reibt. Die Passform anderer decathlon Jacken finde ich besser, viel besser jedoch sind für mich mit breiten Schultern die Bergans Jacken geschnitten.


Softshell plus diese Jacke darüber und Du hast immer warm, wenn Du Dich bewegst. Ideal für Winterspaziergang, Walking etc.

Additional Product Information


Main fabric: 100.0% Polyester ; Coating: 100.0% Polyurethane

Product's waterproofing

The jacket's waterproof was tested in a rain shower with 26 gallons of water / sqm / hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour.

Fabric waterproofing

We measure a fabric's resistance to a water column, in mm (based on the ISO 811 standard). The higher the water pressure resistance, the more waterproof the fabric. A component with a 2000 mm waterproof rating can withstand 2000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours). With waterproofing greater than 10,000 mm, the Alpinism Light jacket therefore offers a very high level of waterproofing.

Fabric breathability

To find out whether a fabric is breathable, we test its evaporate resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more moisture, generated by an active body, is evaporated, and therefore the higher the fabric's breathability.We consider that if: - RET < 9 = highly breathable fabric - 9 < RET < 12 = breathable fabric- RET > 12 = slightly or not breathable fabricThe Alpinism Light jacket's fabric has an RET of 8.


The jacket's hood size makes it compatible with a mountaineering helmet. Its height and depth are adjustable to suit your needs. A semi-rigid visor offers better forehead and eye protection. The high collar provides protection for the lower part of your face.

Pocket and zipper

Outer shell: 2 large pockets that fasten with taped zippers. The pockets are positioned on chest, making it easier to get access to them when wearing a harness. Inner jacket: 1 zip pocket2-way front zipper allowing opening from the bottom and a quick access to harness tie-in loop. The zipper pulls are easy to use with gloves.

Product care

Machine wash at 86°F. Use liquid detergent without fabric conditioner. Close zippers and adjust cuffs before putting in machine. Restore water repellency using a suitable treatment with every wash. A whole range of specially made waterproof and breathable fabric care products are available in our Decathlon stores. Using them will allow you to get the most out of your product throughout its life.
