Perfect
In mid-October, I used it on Mount Echigo Komagatake and Mount Hiragatake. It rained all day on Mount Echigo Komagatake. My backpack got quite wet, but the fleece and down inside the dry bag remained unharmed. I didn’t have a chance to wear it, but I was able to walk without worrying about the rain the next day on Mount Hiragatake.
Hiking without unnecessary stress is comfortable!
