Description
Ultra Soft Alpaca is a finer, more delicate grade of alpaca fibre, offering a smoother and silkier feel. It maintains the thermal and moisture-regulating benefits of regular alpaca but with added comfort against the skin. Its ultra-fine texture reduces friction, making it ideal for everyday wear or as lounge socks. Alpaca is also hypoallergenic, so suitable for sensitive skins. Despite its softness, it remains strong and naturally elastic, helping socks retain their shape with minimal irritation.
Taking inspiration for the perfect red - the iconic British post box. This is a classic, confident red that has become a sock drawer essential.
