Alproof Lite 20 SL
Avalanche backpack
Specification
Description
The Alproof Lite SL equipped with Alpride E2 avalanche airbag system and the very latest supercapacitor technology deploys reliably, quickly and at high pressure, even in freezing cold temperatures. With multiple deployments possible, easy handling, and a quick-access avalanche equipment compartment, plus women-specific SL carry comfort and a snug fit with zero load wobble, the result is a controlled backcountry ride every time. A leg safety strap prevents the pack from being ripped off in an avalanche, while a helmet bag, gear straps and gear loops make this lightweight TÜV-inspected avalanche airbag backpack a serious mountaineering proposition too.

Top features of the Alproof Lite 20 SL
EASY HANDLING FOR EXTRA SAFETY
The waist belt, fully-adjustable sternum strap and leg safety strap all work together to prevent the backpack from being ripped off during an avalanche. The leg strap is also easily secured, without having to undo the waist belt.

LATEST AIRBAG TECHNOLOGY FOR MORE SAFETY
The updated, fully electronic Alpride E2 avalanche airbag system, which features the latest supercapacitor technology, is one of the lightest electronic systems on the market and unaffected by low temperatures. In addition to fast, high-pressure deployment, this proven technology has huge advantages when it comes to maintenance and transport compared to traditional cartridge-powered airbags. An LED status display and trigger action on the outside of the bag makes it easy to assess the system and activate it. Operation is extremely intuitive and is easy to learn during pre-season practice sessions.

SNUG FIT FOR BETTER BALANCE
The lightweight deuter Alpine back system creates a compact, snug fit that keeps the load close to your center of gravity for better carry comfort and also provides effective airflow across the back.

CHOICE OF STOW OPTIONS
An innovative mesh helmet bag connects to the front of the pack and is also detachable has various applications. It’s a standalone mesh helmet bag and it’s also a helmet holder /flap when attached to the front of the pack. This means it can also be used to store other gear like wet clothing etc. inside the bag.

SL Women’s Fit
This model is also available in the SL version. The SL back length is specific for women: on average, women have shorter backs than men. The carrying system in the SL model is therefore somewhat shorter than in the Deuter standard backpacks. In addition, the carrying system is specially adapted to the female anatomy. More information about our fits.

Good Ventilation
thanks to channels between the back padding, covered in breathable mesh fabric.
Compact fit
thanks to the body-hugging ergonomics of the back padding and carry system.
The benefits
The solid, secure fit makes it easier to maintain balance, even in challenging terrain, and make controlled movements. The ergonomics and reliable ventilation also add to the carrying comfort.

TÜV certified

Made without PFAS
This deuter product was manufactured by us without the use of per- and polyfluorinated chemicals. This reduces the use of substances that are harmful to the environment and health.
PFAS is used, among other things, as a coating for rain protection, as they have water, dirt and grease-repellent properties.
Instead, deuter now uses DWR (Durable Water Repellency) impregnation, which is harmless to health and environmentally friendly.

PLUS X AWARD 2022
The expert jury has awarded the deuter Alproof series with the PLUS X AWARD due to High Quality, Ease of Use, Functionality and Ergonomics.
