Vintage 1940s 1950s Men's Thermal Underwear Shorts, Size M L, New Old Stock

A classic example of mid-20th-century utilitarian men's hosiery, specifically designed for insulation during the winter months. These thermal shorts, often referred to as 'pantalones' in the context of period undergarments, represent the textile standards of the 1940s and 1950s.

Historical Context: This type of garment was a staple in civilian and military wardrobes across Europe and the USSR during the post-war era. The manufacturing utilizes heavy-duty knitting machines and traditional finishing techniques, including the application of a factory stamp directly onto the fabric, a common practice before the widespread use of synthetic care labels.

Features and Details:
- Period: 1940s - 1950s
- Technique / Style: Heavy-weight knit with a brushed interior (fleece/fustian texture). Features an elasticated waistband and a traditional fly opening.
- Size: Marked as '5', which corresponds to a modern Men's M - L. Waist (unstretched): approx. 38 cm (15 inches); Total length: approx. 45 cm (17.7 inches).
- Material: 100% Cotton
- Condition: Unworn (New Old Stock). The fabric remains strong and the elastic is functional. Significant yellow spotting (foxing) is present across the front and back due to decades of storage. These marks are consistent with the natural oxidation of organic cotton fibers.

Value and Application: This garment is of high interest for collectors of historical costume, cinematic costume departments, or individuals seeking authentic thermal insulation from natural materials. It serves as a primary source for studying mid-century textile production.
