Lowa Zephyr GTX® Mid boots meet one of the basic requirements of a comfortable shoe – low weight. Model Zephyr GTX is equipped with GORE-TEX® membrane. It provides perfect vapour extraction while remaining water-proof thanks to a Teflon technology. A model without Gore-Tex® technology is available here. Shoes are a great fir for a lighter terrain as well as for paragliding or skydiving.
