GripGrab Women's Merino Blend Thermal Long Sleeve Base Layer At the heart of the GripGrab Women's Merino Blend Thermal Long Sleeve Base Layer is a carefully engineered 50/50 merino wool and polyester blend. Merino wool provides exceptional thermal regulation, helping to keep you warm when temperatures drop while remaining highly breathable to prevent overheating during harder efforts. Naturally soft against the skin and completely itch-free, it delivers outstanding comfort on long rides. The addition of polyester enhances durability, stretch and wrinkle resistance, ensuring the garment maintains its shape and performance ride after ride. Ideal for cycling in cold to mild weather, this Merino base layer also benefits from the naturally anti-odour properties of merino wool, helping to resist microbial build-up and stay fresher for longer between washes. Whether worn as part of a winter layering system or on its own during cooler transitional seasons, this versatile thermal cycling base layer offers the perfect balance of warmth, breathability, comfort and long-lasting performance for dedicated cyclists.
