How do I measure correctly?
- Chest measurement
Horizontally at the most prominent part of the chest. - Waist measurement
Horizontally at the narrowest part of the body. - Hip measurement
Loosely and horizontally at the broadest part of the hips. - Inseam
Standing up, measure the distance from the crotch to the floor (barefoot). - Hand circumference
Wrap the measuring tape loosely around the broadest part of the middle of an open hand (not including the thumb).
Determine the perfect backpack size according to your back length
The size of your backback is important for your comfort. That's why we have developed the ORTOVOX backpacks in different sizes for different back lengths. These three steps provide all the information on how to determine the perfect size and shape for your backpack.

To determine the back length, use a measuring tape to measure yourself from the top of the hip bone up to the 7th cervical vertebra (it clearly protrudes).

The regular back system may be used for a back length from 42 cm to 50 cm.*

The short back system may be used for a back length from 36 cm to 44 cm.*
*The sizes are advisory only. All backpacks should be tried on in person.
S-Backpacks
Ergonomic optimized backpacks for women and men with shorter backs
Our S-backpacks are specially designed for women and men with shorter backs. They are primarily characterized by their significantly shorter backsystem, which makes them perfect for people with short backs. The hip and shoulder straps have also been adapted to the female anatomy: The shoulderstraps are thinner and shorter and have a pronounced S-shape. However, the hip fins are shorter and conical formed.

Regular backpack:
Shoulder straps are wider and longer, and adjusted to fit a more voluminous upper body.
Hip fins are ergonomically shaped.

S-backpack:
Shoulder straps are thinner and shorter and have a pronounced S-shape.
Hip fins are shorter and conical formed.
