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)

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.
