GUIDE TO CHOOSING A SHELL JACKET

What is a Shell Jacket?

A shell jacket is a trusted companion for outdoor enthusiasts and hikers. A well-chosen, high-quality shell jacket is long-lasting and serves its wearer year-round. A good shell jacket provides protection from wind and rain, offers breathability, and withstands heavy use.

A shell jacket typically refers to an outdoor jacket equipped with a waterproof membrane. Its primary function is to shield the wearer from wind and rain. All our shell jackets feature Halti’s own windproof and waterproof DrymaxX® membrane for optimal protection.

Different typed of shell jackets

A shell jacket is a key piece of protective gear for outdoor enthusiasts, and each type of shell jacket offers unique features suited to different activities and needs. 2-layer, 2.5-layer, and 3-layer jackets vary in structure, breathability, and durability. Understanding these differences can help you choose the right jacket for your needs.

  • 2-Layer Jackets: These jackets feature a separate outer fabric and an inner waterproof membrane, making them a great option for everyday outdoor activities. While they are often more affordable, they still provide excellent protection against wind and rain and offer comfort for a variety of conditions.


  • 2.5-Layer Jackets: Combining a durable outer fabric with a waterproof membrane and a lighter protective coating on the inside, these jackets offer increased breathability compared to 2-layer jackets, making them ideal for active outdoor pursuits. They still maintain durability and offer solid protection from the elements, making them perfect for hiking, traveling, and other versatile uses.


  • 3-Layer Jackets: The most advanced option, 3-layer jackets integrate a durable outer fabric, a waterproof membrane, and a protective inner layer, all bonded together. These jackets are built for high performance in demanding conditions, offering exceptional breathability, durability, and protection. They are perfect for mountain environments, intense outdoor adventures, and when you need maximum performance.

When selecting a shell jacket, take the time to review the features of each type to find the one that best fits your specific outdoor activities and conditions.
