A hyper-versatile, hyper-lite, multi-day pack for weekend stints or lengthy thru-hikes.

The 3400 Junction (55L) hiking pack from Hyperlite Mountain Gear is arguably their most iconic pack, and for good reason. This incredibly lightweight pack weighs in at just 0.9kg, less than half the weight of a typical 55L backpack (2.2kg).  Constructed using a highly durable, water-resistant Dyneema fabric, the 3400 Junction is designed to withstand seasonal changes and harsh Australian environments.

The 3400 is a flexible option for those looking for a single pack for all their hiking needs. When extra volume is not required, the 3400 Junction rolls down to roughly 40L making it a great option for shorter, in and out trips. The wide top opening offers quick, uninterrupted entry to the internal compartment so you can say goodbye to fiddly zippers and pockets and get what you need hassle-free.

Hyperlite has also incorporated a generous external mesh pocket for easy access to your gear whether it be an outer layer, food or water filter. This rugged mesh compartment adds an extra 9.8L of external volume which comes in handy on long, self-supported hikes. Personalise your pack system with Hyperlite's range of accessories

Whether you're hiking the Australian Alps Walking Track, Larapinta Trail or Great North Walk, or just escaping to the mountains for a quick overnighter, the Hyperlite 3400 Junction is a one-of-a-kind backpack for any outdoor adventurer.
