Ideally, the rain would never be an issue on the trail. If only that were so! Make sure you have an Osprey Hi-Vis Raincover - Extra Small handy for when an unexpected storm rolls in. The lustrous color and reflective print ensure you stay visible in even the most torrential of downpours. Most importantly, the fabric is seamless and coated with a DWR (durable water repellent) treatment to keep your belongings safe from moisture. It packs up nice and small and is quite content chilling at the bottom of your pack until nature decides otherwise.
