Many autistics are sensitive to changes in temperature. That can be a problem in colder seasons and climates, when you’re constantly moving between the warm indoors and the freezing outdoors, alternatively sweating and shivering. I’ve found a wool felt jacket to be the most comfortable outerwear for such times. Felt is made by pressing fibres together, not by weaving. As a result, warm air is trapped between the fibres, while moisture (such as perspiration or rain) evaporates easily through them. Felt is also a relatively light material, which helps with comfort too.
