The Black Diamond Speed 55 Backpack has plenty of space for all your gear whether you're backpacking over the weekend or climbing ice or alpine for the day. Its removable reActive hip belt moves with your hips so you can hike without any restrictions, and the SwingArm shoulder straps also allow a freedom of movement that you appreciate when you reach through vertical ascents. Black Diamond added its OpenAir mesh to the hip belt, shoulder straps, and the back panel for ultimate breathability that eliminates uncomfortable friction and hot spots. And the V Lite frame keeps the pack sturdy without adding much weight to it. The Speed has a unique roll top access that allows you to extend the top skirt in order to adequately fit all your climbing gear with ease. The 210D nailhead material is very durable and light, and Black Diamond welded 420D abrasion overlays in critical areas so it doesn't tear up against the mountain's rocky ridges. One front and two stretch side sleeves provide room for a wind or rain jacket and water bottles. You also get two loops that accommodate either your trekking poles or ice axes, and a clip for a bike light can keep you visible if your day trip lasts past the sunset.
