Product description

separate compartment for laptops up to 13.3"
made from recycled materials

Our Okab Daypack with a proud 25 l volume is now even more environmentally friendly in its new version! The durable material is recycled and thanks to Eco Finish, it features eco-friendly water repellency without the use of fluorocarbons (PFC) – perfect for a light rain. In all other aspects, this roomy roll-top daypack has stayed faithful to its tried-and-true design. A 13.3" or thin 15" laptop can be stored in the padded main compartment, and can also be removed through a side zip without opening the main compartment. The main and front compartments have clearly arranged organizers to keep things tidy and your water bottle and power bank can be stowed away in the side compartments. An extra sternum strap and straps to attach a helmet make the Okab a great choice for cycling. The well-padded Vent-Urban back and padded, ergonomic shoulder straps ensure comfortable carrying even when fully loaded. The VAUDE Green Shape label stands for environmentally friendly, functional products made from bluesign® certified, sustainable materials.

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.

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

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.
