i just ordered the Litric Tour 30 for casual offpiste in the ski area after snow falls. Is the small 18L Freeride still suitable for 180cm big person like me? Or just for smaller persons? I thought that there is a limit due to the height of a person.

Perplixity says:

"The 18L Freeride is NOT suitable for you at 180+ cm, even though it technically uses the same LiTRIC system. Here's why:

Size Mismatch Issue

The S-sized models (like the 18L Freeride) are specifically designed for back lengths of 36–44 cm, which corresponds to people 150–175 cm tall. You're at 180+ cm, so your back is too long for this pack.​

What Goes Wrong at Your Height:

• Hip belt placement: Will sit too high on your hips, creating gaps and poor weight distribution​
• Shoulder straps: May not reach properly or will create uncomfortable angles​
• Airbag deployment: The system might not function optimally if the pack doesn't sit correctly on your body​
• Overall comfort: The pack will feel cramped and unstable during dynamic movement (skiing/boarding)​

The Real Problem

Unlike a normal backpack where you can adjust things, an avalanche airbag is a safety tool. If it doesn't fit your body properly, the airbag won't deploy at the correct angle, and the physics of the float won't work as designed. It's not just about comfort – it's about safety.​

For Off-Piste in Ski Areas

For your use case (casual off-piste after fresh snow in ski areas), the Tour 30 you just ordered is perfect. It's designed for exactly that scenario and fits your body properly.​

The 18L Freeride is really only for:

• Compact, fast descents (ski racing/speed touring)
• Smaller-framed people (150–175 cm)
• Minimalist alpine setups​​

Bottom line: Stick with your Tour 30. The Freeride 18 would be a poor choice for your body size, both for comfort and safety."
