Backpack fits
deuter backpacks: tailored to your size, fit and functional needs
Depending on how you intend to use your backpack, the features, fit, capacity, or other details will be decisive. deuter offers many different backpacks with capacities ranging from 5 to 75 L so that you can stow everything you need for your journey. In addition, we design our own models with special features that are suited for various kinds of mountain sports, such as adjustable hip belts, back length adjustment, and helmet holders. We also offer versions of all our backpacks that are specially designed for women (adapted to the female anatomy) as well as for particularly big and tall fans of the outdoors. Little adventurers aged two and up will also find the perfect backpack from us.
This is how to measure the right back length for your backpack
For day backpacks, the back length is not as important as it is for hiking backpacks used on multi-day tours. It is important for the back length to be right for proper load distribution on your back and guaranteed comfort. deuter backpacks are adjustable, but you should still select the right back length at the time of purchase. Women often have a shorter back and longer legs, for which our SL models are well suited. Men and tall people, on the other hand, should probably select an EL model. The only sure way to test whether the back length of the backpack really suits you is to try it on. Nevertheless, you can measure the length of your back in advance as a starting point.
Various sizes for women & big and tall people
A direct comparison of the three deuter back lengths is based on the distance between the seventh cervical vertebra and the upper edge of the iliac crest.
On the picture:
- Seventh cervical vertebra
- Iliac crest
- Basically, people of almost the same height can have different back lengths. Choosing the right back length is not just about height.

Slim Line (SL) backpacks: perfect fits for the female anatomy
Our SL (Slim Line) backpacks are designed specifically to fit the female body. They offer not only the right capacity for your activity, but also a carrying system optimized for slimmer builds, shorter backs, and narrower shoulders. Whether you’re hiking, traveling, or commuting, SL models deliver maximum comfort and a secure, ergonomic fit.
Why choose an SL backpack?
Engineered for women. Ideal for anyone with a slim, athletic build.
Women typically have a shorter torso, narrower shoulder width, and a differently shaped hip structure. SL models adapt perfectly to those proportions and ensure a balanced load distribution and pressure‑free carrying comfort. Even though SL backpacks are designed for women, models can also fit some men with slimmer or more compact builds.
What does SL stand for?
SL = Slim Line
A dedicated team of designers and top athletes has been developing the SL line since 2006.
Their goal: to create backpacks that combine technical performance with an anatomically precise fit for women and anyone who prefers a slimmer cut.
The key features of the SL Fit
1. Shorter Back Length
SL models feature a shorter back panel to match the average female torso length. This ensures:
- better weight distribution
- increased freedom of movement
- reduced pressure on the shoulders
Because body shapes vary, SL models may also fit men with shorter backs or narrower frames.
2. Narrower, S‑Shaped Shoulder Straps
The SL shoulder straps are specifically shaped to avoid discomfort in the chest and shoulder area:
- Pronounced S‑shape that follows the body’s contours
- Softer edges to prevent chafing
- Narrower strap spacing, ideal for smaller frames
- Tapered strap ends for a smooth, pressure‑free fit
3. Conically Shaped Hip Fins
The SL hip fins are constructed to match the natural shape of female hips:
- Upward‑converging (conical) design for a snug fit
- Anatomically curved padding
- Optimal load transfer to the pelvic area
This ensures excellent stability without digging in or slipping.
Who are SL backpacks best suited for?
SL models are ideal for:
✔ Women with slim or athletic builds
✔ Anyone with a shorter torso length
✔ Users who prefer a compact, close‑to‑body fit
✔ Men with narrow shoulders or a slim frame
Extra Long (EL) backpacks: the fit for tall people
For tall people, our Extra Long (EL) backpacks offer perfect carrying comfort. Athletes who are between 1.85 and 2.00 m tall often have a hard time finding a suitable backpack. That is why we have lengthened the back lengths of our most popular deuter backpack models by 6 to 9 cm and adjusted them to fit the proportions of taller people. Due to the larger space requirements, we have also adjusted the capacity of the EL models: the size of these backpacks is therefore optimally tailored to the wearer. The back system, properties, and other details of these individual EL backpacks match those of our standard models.
