Deuter Women's Aircontact Ultra 35 + 5L SL Backpack – Lightweight Trekking Pack for Long-Distance Hiking

Overview

The Deuter Women's Aircontact Ultra 35 + 5L SL is designed for thru-hikers who want a lightweight yet capable pack that moves with you on long-distance adventures. Built around the Aircontact back system, it reduces contact surface and uses spacer fabric to promote airflow, helping you stay cooler as you pace uphill and across all-day itineraries. With a dedicated women’s fit (SL), a shorter back length, and ergonomically contoured hip fins, this pack aims to feel balanced and comfortable from first mile to last.

Why it feels comfortable

Key design choices work together to deliver a stable, close-to-the-body carry. The Aircontact back system channels the load toward the center of gravity, while hollow chamber foam cushions enhance ventilation with every movement. A snug, adjustable sternum strap and a pull-forward compression system help secure the load without digging in, so you can focus on the trail ahead.

• Weight-conscious design with a roomy 35 + 5 liter capacity, adaptable via a removable lid.
• Ergonomic, narrow-fit shoulder straps and pronounced S-curve that fits narrower frames.
• Hip fins that cradle the hips for even load transfer on rocky descents and steady ascents.

Durability and materials

Thanks to robust 157D polyamide ripstop Ultra HD fabric, the pack is built to endure rugged environments. The fabric combination contributes to weight efficiency without compromising durability, while the pack’s components are chosen for long-term resilience on multi-day trips and travel alike. The product is Bluesign, ClimatePartner, and Green Button certified, reflecting a responsible approach to manufacturing.

Modularity and options

Versatility is a core strength of the Aircontact Ultra. You can tailor the load and shape by removing the lid and compression straps, enabling a lighter setup when you don’t need extra volume. The pack includes a dedicated drinking system compartment and attachment loops for additional gear, making it easy to customize your kit for the route and season.

• Expandable 5-liter capacity for extra gear when the weather turns or a side trip is planned.
• Attachment loops and mesh side pockets provide quick access to essentials like water bottles and tools.

Use cases and living with the pack

Ideal for hiking, trekking, mountaineering, and travel, the Aircontact Ultra supports endurance journeys where comfort, balance, and adaptability matter. Real-world use cases include long-distance treks where every gram counts, or scaled-down expeditions that benefit from a compact, reliable carrier that still leaves room for essentials.
