The Mammut Trion Light 28+ roll-top is a climbing sack with a very short overall back length of 48 cm and no flap. Ensuring that the backpack sits neatly on your back, allowing easy head tilting and mobility when climbing and belaying, even when wearing a helmet.

Ropes can be attached quickly and easily to the outside and the Trion also offers secure attachments for ice tools and skis. The T-frame “Remove & Climb” frame strut can be removed in the blink of an eye from the outside in situations where you need even more freedom of movement and flexibility. Without the frame and hip belt padding, the weight of the 28+ version falls to an unbelievable 590 g.
