Sub-2-pound Dyneema construction is fully waterproof, tear-resistant, and rated to carry 40 lbs — a combination no other ultralight pack matches. The go-to choice for serious thru-hikers on the PCT, AT, and beyond.
If you're logging serious miles and want the lightest pack that won't fall apart, the Southwest 55 is the answer. It's expensive and minimal, but Dyneema's strength-to-weight ratio is in a class of its own.
“Most cheap packs lack a proper suspension and won't be able to carry an even moderate load comfortably. And all are poorly constructed and risk critical failure (like broken straps) under normal use conditions.”

“Dyneema is the headlining feature here: This burly fabric is known for its incredible strength-to-weight ratio and tear resistance, in addition to being fully waterproof. As a result, the sub-2-pound Southwest 55 is one of the lightest packs here but also ridiculously hardwearing, which is rare among ultralight packs.”
