Product Customer Reviews

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. .
Brilliant used it doing the yorkshire dales three peaks in june very windy on on ingleborough , jacket worked really well
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.
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.

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 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.
Price is little high, but quality is justified

The product benefit
Thumb-hole at the end of the sleeve to avoid all heat loss and for greater comfort when moving.
Thermal comfort and wind-proofing
The wind can cause a considerable drop in the perceived temperature! With an outside temperature of 32°F and 12 mph winds, the perceived temperature will be 14°F. The so-called "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 component (different from waterproof)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents the fabric from becoming saturated with water and keeps it lightweight, breathable and warm. A fabric is made water-repellent by applying a treatment to its outer surface. This treatment must be renewed throughout the garment's lifetime (recommended after every 3 washes).
