Mammut understands pack space is a premium when it comes to ultralight camping and designed the T-Trail + Ambient Light Dry Bag ($50) to pull triple duty. Like most dry bags, it protects your gear from the elements, or conversely, safely carries up to three liters of liquid to and from your base camp. At night, the bag earns its name when paired with the included T-Trail headlamp — serving as a soft diffuser and makeshift lantern that provides enough ambient light to set the mood in all but the largest of tents. More importantly, it frees up a vital space in your equipment pack — leaving you with just enough room for some speakers and a little Marvin Gaye.
