The Hexoskin physiological monitoring shirt does not impair whole-body heat loss during exercise in hot-dry conditions

Appl Physiol Nutr Metab. 2019 Mar;44(3):332-335. doi: 10.1139/apnm-2018-0370. Epub 2018 Oct 18.


Using direct calorimetry, we determined if the Hexoskin shirt (Carré Technologies Inc., Que., Canada), a wearable device for monitoring physiological strain, would compromise whole-body heat loss and exacerbate body heat storage during moderate-intensity activity in hot-dry conditions. The shirt did not impair heat dissipation and resulted in similar body heat storage when worn alone relative to a semi-nude condition (214 vs. 211 kJ) or when worn underneath a work uniform compared with a cotton undershirt (307 vs. 318 kJ).
