Backpack DEUTER Aircontact Ultra 35+5 SL — 35+5 L women's lightweight durable trekking pack

DEUTER Aircontact Ultra 35+5 SL is a women's lightweight trekking backpack with a 35+5 litre capacity designed for multi-day hikes and alpine travel. The pack combines a reduced-weight construction with durable materials and an adjustable SL fit tailored to shorter backs. Multiple access options and a 5-litre expandable collar make it practical for efficient packing, while the Aircontact carrying system balances load transfer and comfort on varied terrain.

Advantages

This backpack offers a balance of low weight and robustness suitable for repeated use on trails. The SL-specific back length and female-oriented shoulder harness improve fit and stability for shorter torsos. The expandable collar increases total volume when needed without adding permanent bulk. Multiple access points and organized compartments simplify loading and retrieving gear, and the design supports even weight distribution for more comfortable long-distance carriage.

Suitable for

• Multi-day trekking and backpacking trips
• Alpine hikes and mountain approaches
• Lightweight tourers who need durable construction
• Hikers with shorter backs seeking an SL fit

Key specifications

• Volume: 35 + 5 litres (expandable collar)
• Target fit: SL (women's/shorter back length)
• Weight: lightweight construction designed for reduced carry weight
• Access: multiple access points for main compartment and lid
• Carrying system: Aircontact-style load transfer and ventilation
• Durability: reinforced fabric areas for abrasion resistance

How to use

Load heavier items close to the back and towards the middle of the pack to maintain balance, using the lower compartment for sleeping gear and the top collar or lid pockets for items you need to access quickly. Adjust the SL shoulder straps and hipbelt so the hipbelt sits on the pelvis and absorbs most of the load, and fine-tune the load-lifter straps and sternum strap for stability. Use the expandable 5 L collar when you need extra capacity and secure external attachments to dedicated straps or loops to keep the centre of gravity close to your back.

Recommendations

For multi-day tours, periodically recheck strap tension and redistribute contents as fuel and water are consumed to keep the pack stable. Treat high-wear areas with routine inspection and clean according to the manufacturer's fabric care guidelines to preserve the lightweight materials and prolong service life.
