British thermal trousers, olive drab/khaki, surplus

Reversible thermal trousers. These take very little space when compressed and warm you up superbly when worn. A must-have for outdoor activity. Used British surplus.

These are meant for situations where you stop moving and stand around instead but also work as a mid-layer for really cold weather.

Elastic waist & cuffs, with zippers running either along the length of the whole legs or a generous amount from the bottom - the models vary. All of them are easy to don without removing your boots. Sometimes comes with a small stuff sack, but don't count on it.

Reversible from OD to tan. The outer is made from nylon, the filling is polyester, just like in most sleeping bags.
