This jacket is entirely made from recycled ripstop nylon. This should mean that it’s a tough and durable jacket with great water resistance. It is coated with DWR (durable water repellent) and water will just slide off the fabric,which means it’s fine to wear in some light rain,but can not beat that sudden downpour! with synthetic fill, not only just windproof, it will also keep you warm during the hiking.
About the construction. The seams are not taped, which means that water can get in through them. This might be an issue in heavy downpours, so you might want to stick to wearing this jacket only in light and mild rain for a short time.
On top of that, All the zippers in this jacket are from YKK. It will do a whole lot in terms of protecting you from the weather.
This jacket is a windbreaker so it only makes sense that it has some wind resistant features. And it does; two features of this jacket directly improve the protection it provides from the wind.
The first is the drawcord at the hem. It allows you to cinch in the jacket at the waist, so that no air can get inside the jacket from below the hem. This is excellent for keeping the wind out and maintaining your body temperature.
There are also the entirely elastic cuffs. While they might not be as wind resistant as proper Velcro adjustable cuffs, entirely elastic is much better than non-elastic and half elastic. It allows for some adjustment of the fit, and the tightness around the wrists helps keep the wind out of the sleeves. The elasticity of the cuffs also mean you are able to pull them over gloves and other bulky garments, which is certainly helpful.
