Designed with your fast and light alpine assaults in mind, the Mammut Trion Light 40 is stripped to the essentials. That doesn't mean you can't carry your gear in comfort, either. Mammut's butterfly suspension delivers optimal load transfer to your hips yet allows your upper body the freedom of movement it needs whether you're swinging an ice tool or cutting fresh skin tracks. On that long awaited day when the weather clears and the summit is in sight, you can trim the Trion Light even further by removing the hip belt padding. A reinforced ski carrier, 2 ice axe carriers, and a daisy chain give you multiple gear-hauling options.
