Men's U-Shaped Breathable Briefs in Viscose Knit Fabric, Asian Sizes M to 3XL

Designed for daily comfort and practicality, these men's briefs feature a U-shaped or 'big bag' cut that provides a supportive and comfortable fit. Crafted from a knitted viscose fabric, they offer breathability suitable for all-day wear. Available in a range of five solid colours – black, white, grey, green, and brown – they provide a versatile wardrobe staple. The sizing is tailored for Asian body types, covering a weight range from approximately 47.5kg to 100kg across sizes M, L, XL, 2XL, and 3XL. It is important to consult the size chart carefully, as these sizes typically run 1-2 sizes smaller than European or American equivalents.
Features and Construction

This underwear focuses on straightforward construction and fit for daily use. The design prioritises comfort through its material choice and cut.
Material and Build
The briefs are constructed from viscose fabric, known for its softness and breathable properties. The fabric is knitted, which adds flexibility and can contribute to a comfortable, non-restrictive feel against the skin. The product is described as having a solid-colour pattern, available in the five specified shades.
Size and Practical Fit
The sizing follows Asian standards, with a detailed chart linking sizes M through 3XL to specific weight ranges. Size M fits weights between 47.50kg and 70.00kg, L fits 70.00kg to 80.00kg, XL fits 70.00kg to 90.00kg, 2XL fits 80.00kg to 100.00kg, and 3XL fits 90.00kg to 100.00kg. The 'U-shaped' or 'big bag' style is designed to offer a supportive and accommodating fit. Buyers are advised that Asian sizing runs smaller and to select the larger option if their measurements fall between two sizes, with a note that manual measurement can result in a 2-3cm variance.
