We're tempted to say that the Neptune GTX jacket is a direct replacement of the Legacy GTX jacket but it’s actually a lot more than that. We've noticed in the past few years that most serious riders shopping for high-end technical riding gear opt for versatility. Many riders are looking for products that can be adapted to varying weather conditions. The traditional fixed waterproof liner—whether it's our own non-removable hydratex® lining or a GORE-TEX® performance lining—simply doesn’t offer that flexibility. So we've decided to delete the Legacy GTX from our collection to offer something better and more versatile. By equipping the Neptune GTX jacket with a removable waterproof GORE-TEX® Paclite® membrane and removable thermal liner, the jacket becomes a true four-season option for both commuters and serious touring riders. Without the membrane, the air vents allow in outside air to directly cool the body on hot summer days.
