Review highlights top thermal clothing options for winter warmth

Thermal clothing has evolved from basic, unattractive designs to stylish options that provide warmth. A recent review tested five brands, highlighting their heat retention capabilities using a thermal camera. The results show significant differences in warmth among the brands. Damart's Thermolactyl line offers various warmth levels, with a model noting the thin material still provides good heat retention. M&S features nearly 200 thermal options, with some pieces retaining heat but not as effectively as others. Primark offers budget-friendly thermals that perform well for their price. Next's Thermogen line is stylish but less effective at retaining heat, while Uniqlo's Heattech range stands out for its superior warmth and fashionable designs. The review emphasizes the importance of both style and functionality in modern thermal wear.
