From accordions to armadillos, it is clear that an expandable-collapsible design can be useful. Dynafit has recognized this wisdom in their Speed 25+3 Pack. Encompassing a litany of handy features for light n’ fast ski touring, this pack’s claim to fame is an additional zipper that reveals an extra three liters of storage space. This might come in handy carrying an extra puffy for long outings, pulling some extra weight for fatiguing partners, or hauling your favorite 28-liter water bottle. More conventionally sized hydration systems can thread through the top of this pack, making hydration and speed on the skin track mutually compatible. Circling back to those handy features mentioned earlier, a detachable ski carry and ice-axe speed attachment are sure to please everyone except the “enjoys removing their pack on a windy ridgeline” crowd. Height-adjustable breast straps plus breathable shoulder straps make strapping in a comfortable, literal cinch. To keep things sorted out inside the pack, a dedicated compartment for avalanche gear makes digging around for a shovel handle a thing of the past. Just as thoughtful is an externally accessible Safety Box to reduce the odds those crampons unexpectedly mingle with your lightweight softshell. To go far, go fast: choosing between speed and carrying capacity is unnecessary with the Dynafit Speed 25+3.
