To keep things light, simple, and comfy on our multi-day missions, we load up the Osprey Aura AG LT 50L Pack. The pared down design lowers the gram count by giving us the organization we need without the weight and fuss of added extras, while the seamless suspended mesh back panel keeps airflow up and friction down when we're grinding up never-ending steeps. When gray clouds release their stores, we deploy the included rain cover to keep our gear dry.
