Alpha FL 45 Backpack

N400-AC² Weather Protection

A unique, highly durable, weather-resistant nylon fabric. Polyurethane coated inside and out, the fabric is water, snow, and even air impermeable to protect the contents of your bag, with a pigmented white interior reflects light for heightened visibility.

Alpha FL 45 Backpack

RollTop™ Closure

A weatherproof seal that, when not needed, is stored inside the pack out of the way. Easy to use with gloved hands, this closure system seals out moisture and has a wide mouth opening that allows quick access to pack contents.

Alpha FL 45 Backpack

Fully Taped Seams

With fully taped (or sealed) seams, every possible seam in the garment has been sealed up with a waterproof tape to prevent water and snow seeping through the stitching, so absolutely no liquid makes its way into your gear.

Alpha FL 45 Backpack

Ripstop stops rips!

Ripstop fabrics are fabrics woven with a special reinforcing technique that makes them resistant to tearing and ripping - the same technique used in sails, hot air balloons, kites, and parachutes (disclaimer: item will not work as a parachute… or at least hasn’t been tested to).

4 integrated side lash points and 6 on the front for lashing extra gear to the pack's exterior such as sleeping pads or skis
Two ice axe loops
Six integrated front lash points
Large, webbing pull-tabs for quick and easy, glove-friendly access
Dual haul loops/carry handles permit hauling or clipping off at a snow anchor
Extendable collar with drawcord for additional capacity
