Osprey Packs

Seral 4L Hydration Pack

A bluesign® APPROVED product means that the materials used in its production are environmentally friendly and safe for workers. This certification ensures that harmful substances are minimized during manufacturing and promotes sustainable practices, making it a great choice for eco-conscious consumers.

PFC-free DWR treatment is crucial because it makes fabrics water-resistant without using harmful perfluorinated chemicals. This eco-friendly alternative helps protect the environment and human health while still providing the durability and performance needed for outdoor activities.

Osprey Hydraulics are specialized hydration reservoirs designed for easy water access during activities like hiking and biking. They are engineered for efficient water flow, allowing you to stay hydrated without interrupting your adventure, making them a convenient addition to your gear.

The AirScape back panel features a ventilated design with channels that promote airflow, helping to keep you cool and comfortable while you move. This technology reduces sweat buildup and enhances overall comfort, making it ideal for long hikes or strenuous activities.

A lumbar pack is designed to sit on your lower back, providing a stable fit that reduces shoulder strain. This design allows for easy access to hydration and essentials while keeping your hands free, making it perfect for biking, hiking, or any activity where mobility is key.

While PFC-free DWR treatment provides excellent water resistance, it is best suited for light to moderate rain. For heavy rain conditions, consider using additional waterproof covers or gear to ensure your belongings stay dry, as no treatment can guarantee complete waterproofing.
