The choice of a Wise trail jacket depends on the weather conditions and your need for protection (wind, cold, or rain).

Thermalshell 112: ultra-light and breathable windbreaker, ideal for intense efforts and windy conditions
Thermalshell 122: light merino wool insulation, perfect for changing conditions and long distances
Thermalshell 333: maximum thermal protection, designed for cold and demanding environments

In summary, choose your jacket according to your needs:

Wind and intensity → Thermalshell 112
Versatility → Thermalshell 122
Cold → Thermalshell 333
Rain → Rainshell 253

To choose the right size for the Wise trail jacket (Thermalshell 112), it is recommended to base your choice on your chest and waist measurements to ensure a comfortable and high-performance fit during your run.

Jacket Size Guide:

XXS: chest 78–83 cm | waist 66–70 cm
XS: chest 84–89 cm | waist 71–76 cm
S: chest 90–94 cm | waist 77–81 cm
M: chest 95–99 cm | waist 82–86 cm
L: chest 100–104 cm | waist 87–91 cm
XL: chest 105–110 cm | waist 92–97 cm

Measure your chest circumference at the widest part of your chest, and your waist circumference just above your hips.

Between two sizes: what to choose?

- A size up will provide more comfort and make it easier to wear with additional layers.
- A size down will offer a more fitted feel, ideal for reducing wind resistance and optimizing performance.

How to tell if the size is right?

A well-fitting trail jacket should:

- Stay close to the body without compressing
- Allow good freedom of movement
- Be comfortable with or without a pack
- Not flap in the wind
