WIND JACKET for thru hike in New zealand

I weared it 5 months every single day during my thrue hike in New Zealand (TE ARAROA 3200 kms). Currently it is still good, there are not holes and the fabric are still pretty good. i like it because it is pretty light and the jacket can dry pretty quickly (sweat, rain..). I used it under rain, sun, storm. .

Great jacket

Bought this jacket for my grandson who absolutely loves.

Great garment

I wanted something that would keep the wind off me whilst walking. This is great; it's light, lovely long sleeves with thumb holes, the zip goes just high enough to do the job of keeping your neck warm without leaving you feeling throttled, and miraculously, the hood stays up without any cord to tighten it. If you get caught in a shower, it also does a fair job of keeping the rain off you. All this, and it's light and easy to roll up and put in the smallest of bags. Love it.

My go-to jacket for 5-12 degrees temperature

For hiking, I wear this with a Forclaz Techwool 190 merino wool base layer and it keeps me at a comfortable temperature while I am moving. I bought a fairly close fitting size, so that it doesn't flap about and am happy with this choice. It gives me about as much added warmth as a fleece, but with added wind protection and some rain protection, too. I particularly like the hood, which is close-fitting and made from really thin material. When you are not using the hood, it doesn't get in the way at all. I sometimes wear a cap under the hood, to provide a brim - particularly when it starts raining. The water repellency is good. I don't need to rummage in my pack for a waterproof at the first sign of rain. On a showery day, I am happy walking through 10-15 minutes of rain without worrying about getting wet. The pockets are a good size. Large enough for a buff and gloves and still fit your hands in, or gloves and buff is one side with a hat in the other. Below 5 degrees, I would wear this as a mid-layer and put a jacket over the top. Above 12 degrees and I switch to just wearing a shirt. If I could change anything about this jacket, it would be the length of the sleeves. I don't need the long sleeves with thumb holes. I may cut them shorter and sew a new hem. Having said that, the material is thin enough that, even bunched up, the extra sleeve length doesn't cause a problem.

Inaccurate description

Although this jacket is good quality, it does not have all the features from this page. I was disappointed to find there is no drawcord on the hem as advertised and no adjustable sleeves. This means that it will be no good for trad climbing or long mountain days as the wind easily gets in as the waist is loose.

Thank you for your feedback on the Forclaz 600 jacket and I apologise for the delayed response. I also apologise for the miscommunication and have removed the false information form the product page. Should you still own the jacket and remain dissatisfied, please drop back into the store and we shall find a suitable solution for you.

Brilliant jacket for activity

I really like this jacket. I tend to wear it when warming up for running and/or standing around before a race. It is nicely wind resistant and surprisingly water repellant too, but I would not say that it is a warm jacket - you still need to be doing activity to stay warm in this really (if wearing in chilly weather...!). I like the fact that it is stretchy. I am tempted to wear it rock climbing but I like it too much to risk ruining it on the rocks!

Great jacket for price

Great jacket for price to cut the chill on breezy summer days. Shrugs off light showers too. Light but not flimsy. Only caveat would be to double check the sizing, I'm usually on the smaller side of medium but the jacket is a close fit, not a problem in this case as I bought it for cycling

Love it. Hardly a day when I don't look forward to pulling it on.

Additional Product Information

  • 88% Polyester cationic


  • 100% Polyester cationic

Sizing and fit information

Quite a close-fitting cut. The jacket's inner volume allows you to wear it over a thin second layer such as a micro-fleece.

Pocket system

2 hand pockets + 1 chest pocket with zipper fastener.

Jacket hem drawstring

Elastic drawstrings and toggles.

The product benefit

The thumb loop on the cuff to prevent loss of heat and more comfort when moving.

Thermal comfort and windproof

The wind causes the perceived temperature to decrease considerably! With an outside temperature of 32°F and 12 mph winds, it will feel like the temperature is 15°F. "Windproof" components help eliminate the discomfort linked to this "freezing effect." They are very effective at reducing heat loss by creating a barrier against the wind.

Water-repellent property of the component (different from waterproofing)

The water-repellent property of a fabric is its ability to make water run off its surface without absorbing it. In this way, the fabric does not become waterlogged. A fabric becomes water-repellent by applying a treatment to its outer surface. This treatment needs to be renewed during the lifetime of the garment (we recommend every 3 washes) by placing the jacket in the dryer for 10 minutes at a low temperature. You can also use the FORCLAZ re-waterproofing spray (ref 8554908)

A score for comparing the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle using different indicators. An overall ABCDE rating is given to help you easily identify products with the best environmental performance by comparing and contrasting products of the same type (T-shirts, pants, backpacks, etc.). Decathlon actively promotes this environmental rating initiative. For more information:
