Yes, the pack features an innovative adjustable torso system. This allows you to fine-tune the fit to your specific back length, ensuring the weight is properly distributed across your hips and shoulders.
The NanoFly fabric is reinforced with UHMWPE ripstop, which is an ultra-high-molecular-weight polyethylene. This makes the pack significantly more resistant to abrasions and tears, specifically designed to handle the rigors of alpine climbing and cragging.
Yes, the lid is removable. When you remove it, you can use the integrated FlapJacket feature to cover the main compartment, keeping your gear secure while streamlining the pack's profile.
Yes, the Tempest Pro 40 is hydration compatible. It includes an internal sleeve to hold your reservoir securely while you are on the move.
