The Men's three-in-one jacket (polar liner) is also known as a 2-piece jacket. It can be worn alone with the outer jacket and the inner tank alone, and can be combined and worn together, so it is called a Men's three-in-one jacket (polar liner). The main functions are windproof, snowproof, waterproof, rainproof and warm. So how to choose?

1. To be completely waterproof for each Men's three-in-one jacket (polar liner), hot-pressed tape must be used at all seams to prevent water leakage at the needle eye. Carefully check whether the tapes inside the clothes are flat and whether there is any blistering. This is very important for the waterproof performance of the garment.

2. There are many jackets and trousers that add an extra dot of glue at the junction of two or more glue strips to prevent the head of the glue strip from warping for a long time. This process is mostly used on high-end three-layer rubber jackets.

3. The main zipper of the three-in-one jacket is either a waterproof zipper or a placket to prevent the infiltration of rainwater. If it is an ordinary zipper with a placket, pay attention to whether there is a folded edge at the placket. This design allows rainwater to flow down the folded edge without seeping into the zipper.

4. Whether the hat can block the wind and rain well, and whether the head can move freely after wearing it. If it is used for ice climbing, snow mountain climbing and other activities, also consider the activities after wearing the helmet.

5. Whether the tightening method of the cuffs of the jacket is appropriate, this involves activities in rainy and snowy weather with thick gloves.

6. Whether there is a windproof skirt on the hem or waist of the Men's three-in-one jacket (polar liner), if there is no windproof skirt, whether there is a drawstring to tighten the clothes to prevent the wind and snow from pouring into the body from the hem in harsh environments.
