还有个更保暖的,不是Gore-Tex的,但屁股和腰部保温层好像比较好 (With a well-insulated core, adding extra insulation throughout the sleeves would just add extra bulk. Therefore, we used 150-gram insulation to cut down the size and add extra mobility. On top of that, we put in articulated elbows and knees and a low-bulk cuff design. When the torso is insulated, there is greater flow of warm blood to your outer extremities, such as your fingers or toes. Wrapping your body in 200-gram superior-insulating Thinsulate Platinum keeps you warm from head to toe. Your core temperature is largely controlled by the spinal column. That's why we've put 500-gram insulation in the seat and 300-gram insulation down the spine and through the kidneys. The hood features 100-gram insulation)。可这个好像不防水,而且用户说体积大,重量也很重。
