The Deuter Speed Lite 40+10L is a top-of-the-line hydration pack designed for serious trail runners and ultra-marathoners who need a reliable, comfortable, and feature-rich companion on their long-distance adventures.

First impressions of the pack are overwhelmingly positive. The first thing that strikes you is its sleek and lightweight design, made possible by Deuter’s proprietary Aircontact Plus technology. This innovative material allows for exceptional breathability, flexibility, and durability while maintaining an impressively low weight.

Key Specifications:

• Volume: 50L
• Weight: 1.25 kg (2.76 lbs)
• Water Capacity: 3L Hydration Bladder
• Dimensions: 53 x 24 x 18 cm (20.9 x 9.4 x 7 in)

One of the standout features of the Speed Lite is its impressive ventilation system, which ensures that your back stays cool and dry even during the most intense workouts. The pack’s ergonomic design allows for a full range of motion, making it perfect for running, hiking, or climbing.

The Speed Lite also boasts an impressive array of storage options, including multiple compartments, pockets, and a dedicated hydration sleeve. This means you can carry everything from water bottles to snacks, extra clothing, and even a first-aid kit with ease.

The pack’s construction is also noteworthy, featuring Deuter’s signature Airstream panels for enhanced ventilation and airflow. The result is a pack that feels remarkably light and agile on your back, making it an ideal choice for long-distance running or hiking.

Other notable features include:

• Reflective strips for increased visibility in low-light conditions
