The Ultralighter's compact companion, featuring tough Hardline-with-Dyneema pockets, and designed to thrive in scrubby trails and rocky environments 

The Southwest 40 (formerly known as the 2400) Pack from Hyperlite Mountain Gear is a super nimble, almost weightless pack coming in at just 850g. Constructed using a highly durable, water-resistant Dyneema fabric, the Southwest 40 is designed to withstand seasonal changes and harsh Australian environments. 

The Southwest 40 is a compact companion for streamlined hikers venturing into the wilderness for an overnighter or long weekend. The wide top opening offers quick, uninterrupted entry to the internal compartment so you can say goodbye to fiddly zippers and excess pockets and get what you need hassle-free.

Hyperlite has also incorporated three generous, external Dyneema pockets for easy access to your gear whether it be an outer layer, food or water filter. This rugged compartment adds an extra 9.8L of external volume which comes in handy on the trail. Personalise your pack system with Hyperlite's range of accessories

Whether you're hiking the Grand High Tops walk in the Warrumbungles or escaping to the coast for a quick overnighter, the Hyperlite Southwest 40 is a one-of-a-kind backpack for any ultralight expedition.
