Which backpack fits my back length?

It's easy to find out which VAUDE backpack fits your back length: simply measure yourself with a tape measure and compare your back length with our table.

Measure your back length

Backpack sizes

Some of the backpacks' product names include size information. The designation "M" stands for medium, i.e. a medium size. This medium size is universally suitable and is perfect for most users. "L" stands for Large, i.e. a large size, "XL" for Extra Large, an extra large size. If no specific size information appears in the product name, it is usually a standard size.

Size	Height
Unisex: XL	ca. 180 cm - 203 cm
Unisex: M/L	ca. 162 cm - 185 cm
Women's Size	ca. 155 cm - 178 cm

Frame bags

Fork bags

Sleeping bag size information

The product names of some sleeping bags include size information. The designation "S" stands for small, i.e. a small size, while "XL" stands for extra large. If no specific size information such as "S" or "XL" appears in the product name, it is usually a standard size or "Regular". (Indicated sizes in cm)

Size	Height
Regular	165-190
S	150-170
XL	185-205
Kids	105-135
Youth	130-165

Sleeping bag zip position

Zip	Info
left	The zip is on the left, suitable for right-handed people
right	The zip is on the right, suitable for left-handers

A few tips on choosing the right zip position: Right-handed people choose a sleeping bag with the zip on the left, as they can comfortably reach across the body to the zip with their right hand. Left-handed people choose a sleeping bag with a zip on the right so that they can easily reach the zip with their left hand. If you want to combine two sleeping bags, make sure you choose one with a zip on the right and one with a zip on the left. The choice of sleeping bag should also take into account the position of the tent entrance so that you can always get in and out comfortably.

How to measure correctly?

To ensure your VAUDE clothing fits perfectly, it is important to take your measurements correctly. Here's how:

Chest: Measure the circumference at the widest point of your chest – ideally while standing upright with your arms hanging loosely at your sides.
Waist: Measure the circumference at the narrowest point of your waist – usually just above the belly button.
Hips: Measure around your hips at the widest point of your buttocks.
Inseam: Measure straight down from the top of your inner thigh (crotch) to your ankle.

Ich bin zufrieden

Review by Thomas
Mar 4, 2026

Ich hatte vorher die Blase eines Mitbewerbers und jetzt die zweite von Vaude. Blase und Mundstück von Vaude sind besser zu reinigen und einfach hygienischer. Obwohl das Material dünn ist, ist die Blase sehr robust. Ich kann das Trinksystem empfehlen.

Robuste Trinkblase, schwer zu reinigen

Review by Karl
Aug 31, 2025

Die Trinkblase ist sehr robust, hält auch hoher Belastung Stand und bleibt stets dicht. Allerdings ist das Reinigen eine Qual, insbesondere wenn man den Fehler macht und die beiden Silikonschienen innen auseinander zieht. Diese wieder zusammenzufügen ist sehr mühsam. Zum reinigen am besten lediglich auf links drehen.

Response

Hallo Karl,
vielen Dank für deine Bewertung.
Es tut uns sehr leid, dass du Probleme bei der Reinigung der Trinkblase hast.
Schau' dir dazu gerne auch das Informationsvideo auf der Produktseite an - dort wird die Reinigung gut dargestellt.

Schmeckt nicht und ist undicht

Review by Dirk
Aug 27, 2025

Ach im dritten Jahr der Nutzung geben die Trinkblasen noch ihren typischen unangenehmen Geschmack ans Wasser ab. Ich würde es als eine „blumig-chemische“ Note bezeichnen. Eine der beiden Blasen ist außerdem plötzlich im Bereich der Öffnung undicht geworden. Die Klemmschiene dichtet ganz außen nicht mehr ab, so dass aus den Ecken das Wasser quillt (also keine Loch oder keine undichte Schweißnaht, sondern die simple Mechanik versagt).
