還記得高中幾何課學過的梯形嗎？原來這個有趣的形狀非常適合讓睡袋保持溫暖。我們的梯形擋板結構只是 Cosmic Down 仍是我們最愛的三季明星的原因之一。我們也喜愛擴大的自然貼合腳部空間，讓雙腳更舒適、附拉鍊的收納口袋、全回收布料，以及無 PFAS 的 DWR 防潑水處理。Cosmic Down 就是全方位的完美選擇。
Took this out on a 28°F night and stayed toasty the whole time, which I honestly didn't expect from a 20-degree bag. The trapezoidal baffles really do seem to hold heat better than my old rectangular bag, and the down lofts up nicely after you shake it out.
I'm a cold sleeper and usually wake up shivering, but the trapezoidal baffles on this bag actually kept the warmth where I needed it. Took it out on a chilly 30-degree night with just a base layer and stayed toasty the whole time.
Slept at about 25 degrees last weekend and stayed toasty all night. The trapezoidal baffles really do seem to keep the heat from sliding around, and I didn't wake up with cold spots along the seams.
