Abstract Purpose Heat sensitivity is a common contraindication in people with Multiple Sclerosis (pwMS), and physical fatigue is one of the most frequently reported symptoms that can affect quality of life. Increases in body temperature may exacerbate fatigue and heat-related symptoms. Decreasing body temperature via cooling devices may mitigate disease symptoms and improve physical abilities and quality of life. This study evaluates the effects of a cooling vest with sham condition on walking capacity using a commercially-available cooling vest specifically designed for pwMS. Methods A counter-balanced, cross-over design was used to assess the effects of a cooling vest (CryoVest Comfort, CryoInnov, France) (COLD) from a menthol-induced sham condition (CON) on ground walking time to exhaustion (Tex, s) and distance at exhaustion (Dex, m) in ambulatory pwMS. Secondary outcomes were heart rate (HR, bpm), thermal sensation (Tsens), skin chest (Tchest) and back (Tback) temperature. Results Ten females with Multiple Sclerosis (59 ± 9 years, EDSS 3.0–5.5) participated to the study. During COLD, pwMS walked significantly longer (1896 ± 602 vs. 1399 ± 404 s, p
