• The pack material itself guarantees waterproofness. Seam and attachment points are meticulously sealed with Dyneema® Composite Fabric Tape, while hydrophobic thread further enhances water resistance, ensuring the pack's resilience.

• Ample space accommodates finely tuned ultralight setups, including provisions for multiple days' worth of sustenance.

• Three belt positions permit customization of the optional webbing belt's height for varying torso dimensions. Measuring 2.5 cm in width, the optional belt can adjust up to a maximum of approximately 127 cm in circumference, contributing 34 grams to the overall weight. It can be tailored or detached.

• For those seeking added belt cushioning, separate belt pouches with integrated padding are available.

• The roll-top closure boasts a stiffened opening to prevent water infiltration and enables top compression as your gear load diminishes.

• Included is a top strap for securing items atop the pack. An upgrade option, the Nero V-Top Strap, supports carrying heavier items such as Bear Canisters.

• A generously sized stretchy mesh center pocket offers swift access to essentials. This mesh pocket aids in drying damp garments and provides clear visibility of stored items.

• Shoulder comfort is ensured with thick, broad padded contoured straps. These straps feature a daisy chain for attaching items like shoulder pouches, water bottle sleeves, and a position-adjustable sternum strap. Added cushioning is provided by the 3D mesh underside of the shoulder straps.

• Non-stretch Dyneema® cord-based side compression straps compact the pack's volume and accommodate taller gear items like trekking poles or an umbrella. Side pockets are strategically positioned for easy access and are tailored to fit 1 to 1.5 liter bottles. Drainage holes and elastic closures enhance their functionality.

• Loops along the sides and front permit attachment of optional add-ons, including top side pockets, shock cord lashing, and ice axe loops.

• An enclosed-cell foam sit pad (28 cm x 39.4 cm) adds 29 grams to the pack's weight, providing back cushioning. Secured by shock cord, the pad is swiftly detachable, and both the cord (8.5 g) and pad are replaceable.

• The shock cord's adjustability accommodates folded sleeping pads up to 51 cm in height or taller sit pads 

• The pack can be folded for easy storage or carried onboard as hand luggage.
