• • Cisgender man between the ages of 18-28 years
• • been cleared by the medical monitor for this study
• • VO2max \> 45ml/kg/min
• • Aerobically active (at least 30 minutes of aerobic exercise 4-5 days per week)
• Exclusion Criteria:
• • Have a current musculoskeletal injury that would limit their physical activity or preclude the participant from walking, jogging, running, sprinting, or cutting.

• • Fever or current illness at the time of testing
• • History of cardiovascular, metabolic, or respiratory disease
• • A family member died for no apparent reason, had a heart attack, died from heart problems, or sudden death before the age of 50
• • Current musculoskeletal injury that limits their physical activity
• • Currently taking a medication that is known to influence body temperature (amphetamines, antihypertensives, anticholinergics, acetaminophen, diuretics, NSAIDs, aspirin)
• • Identify as cisgender woman, transgender man or transgender woman. Cisgender women, Transgender men, and transgender women are excluded from the current study because the sponsor of the study has requested that this testing be done in physically active cisgender males. It is assumed that they either currently have data on women or transgender women/men to compare this to or have a strategic initiative from a marketing or business perspective that only involves cisgender men.
• • Have a history of heat related illness
• • Throat or gastroesophageal diseases including gastroesophageal reflux disease (aka, GERD) or difficulty swallowing
• • Have any allergies or adverse reactions to the cold (e.g. Cold Uticaria, Raynauds Phenomenon/Disease, or Cryoglobulinanemia)
