The 'Merino Thermovent Hoodie' from Ortovox is designed to be versatile and suitable for a variety of weather conditions, but is particularly suitable for the transition period and for activities in cold conditions.

- Transition period and winter: The sweatshirt is made of 99% fine merino wool, which offers excellent insulation and temperature and moisture regulation, making it ideal for cold days and winter activities such as ski mountaineering.
- Transition period: It is also comfortable for cold summer nights and the transition period thanks to its mesh structure that provides excellent breathability and ventilation.

Thus, although it can be worn in different seasons, it is particularly suitable for cold conditions.
