Starfleet uniform (environmental variants)

This page details the various environmental variants seen Starfleet uniforms of all eras.

Cold weather gear
In the unifrom of the late-2360s cold weather gear consisted of a long coat to provide additional thermal insulation. The jacket was mauve coloured with black/grey striped areas atop the shoulders and down the sides, in a similar pattern to colour and black arrangement of the standard uniform of the era. The coats were closed down the middle of the front with some manner of fastening and a belt around the waist. The coats featured two large pockets below the belt on the front and grey circle on the upper chest in the same location a combadge would ordinarily be worn on a standard uniform.

These coats are seemingly standard equipment in type-6 shuttlecraft, as Ro Laren, Geordi La Forge and Worf were able to wear them when they crashed the shuttlecraft Goddard in 2369. 
 * Note the image shows the uniforms in low light conditions so the colour appear greyer than in ordinary lighting.
