Klattermusen Tjalve 2.0 Backpack 10L

The Klattermusen Tjalve 2.0 Backpack 10L in Cloud Berry is a technical carry system engineered for stability and speed during high-output outdoor activities. Utilising a lightweight Retina® recycled polyamide and a ventilated 3D-mesh back panel, this 10-litre daypack ensures your gear stays secure and your back stays cool on the move. The innovative 4-S sternum strap system and cinch opening allow the pack to stay close to your centre of gravity, providing a bounce-free experience for trail runners and hikers alike.

At Urban Industry we recommend / Ideal For

• High-intensity trail running and fast-paced hiking where a low-profile, stable pack is required.
• Building a sustainable technical kit with gear made from 50% post-consumer and 50% pre-consumer recycled materials.
• Short mountain missions and summit pushes that only require the absolute 10L essentials.
• Active commuting or cycling where a lightweight 320g pack provides a non-restrictive carry.

Our Style, Fit & Sizing Recommendations

• This pack features a 10 litre capacity, offering an ultra-slim 45 x 16 x 20 cm profile that hugs the back.
• The 4-S System is designed to divide pressure evenly across the chest, preventing the straps from digging in during heavy breathing.
• The adjustable shoulder straps and removable waist belt allow for a fully customised fit regardless of your layering.
• We recommend utilising the external bungee cords to compress the pack when it is not fully loaded to maintain maximum stability.

Washing & Care Instructions

• Hand wash only at a maximum temperature of 40°C to protect the technical Retina® fabric and PU coating.
• Wipe the Cloud Berry exterior with a damp cloth after use to remove surface dirt and maintain the vibrant colour.
• Air dry the pack naturally away from direct heat sources and do not use a tumble dryer.
• Do not bleach, iron, or dry clean the backpack, as these processes can compromise the recycled fibres.
• Ensure the 3D-mesh back panel is completely dry before storing the pack to maintain long-term freshness.

Our Tjalve 2.0 Backpack FAQs

1. How much does this pack weigh?
   It is exceptionally light, weighing only 320g, which helps reduce fatigue during speed-focused activities.

2. What is the benefit of the 4-S sternum strap?
   It is a four-point attachment system that distributes tension across the chest much more effectively than a standard single strap, preventing the bag from bouncing while you run.

3. Is the bag waterproof?
   While the Retina® fabric has a PU coating and a water column of over 300mm, we recommend using an internal dry bag for your electronics during heavy downpours.

4. Can I remove the waist strap?
   Yes, the waist belt uses simple toggles, making it easy to remove if you want to save weight or prefer a looser fit for casual use.
