Thermal Ski Onesie

This thermal jumpsuit leans into the high-compression aesthetic of 90s activewear, utilizing a dense, gridded knit that provides substantial structure. The contrast black side-paneling creates a graphic vertical line that visually elongates the frame, while the center-front zip allows for an adjustable neckline. It functions as a second skin, trading the softness of cotton for the reliable, sweat-wicking grip of a nylon-spandex blend.

Safety Rating: Lowest

Analysis: The garment is constructed from an 85% nylon and 15% spandex blend, both of which are petroleum-derived synthetic polymers. These materials are non-breathable and prone to trapping heat and moisture against the skin while shedding microplastics during wash cycles.
