Synthetic material clothing has become an extremely large market for athletes and athletic departments alike. While these materials were originally designed to keep an athlete cool and dry in hot conditions, there have also been products designed to keep athletes warm and dry in cold conditions. While numerous studies have examined the effect of synthetic material clothing on individuals in warm climates, very few have examined the effects in cold environments. Of those few, virtually none have examined strictly the effect of specific base layers on body temperature without additional clothing. The purpose of this study was to determine to what extent these materials affected body temperature in cold weather environments without additional clothing to aid in the maintenance of body temperature. |
