Windproof protection & water resistance with thermal insulation for ultimate comfort in poor conditions. Thermolite fabric is used for its impressive insulation properties given its weight so you can stay warmer without being restricted by a bulky fabric. The High Performance Repel Teflon fabric protector is added to give the outer material plenty of water repellence so although it is not fully waterproof it will shed off showers & drizzle easily. The skullcap is cut so that it is snug fitting & the flat locked seams mean that it sits well under a helmet. Reflective logos increase visibility in lower light conditions & at night time.
