Pack Care & Maintenance Instructions

To maximize the lifespan of your tactical rucksack, follow these professional care guidelines:
  1. Cleaning: Hand wash only using a damp cloth, mild soap, and lukewarm water.
  2. Drying: Hang the bag upside down in a well-ventilated, shaded outdoor area. Never use a mechanical dryer.
  3. Chemicals: Avoid harsh detergents, bleach, or fabric softeners, as they destroy the water-resistant coating.
  4. Storage: Ensure the rucksack is 100% dry before storing it in a cool, dark closet to prevent mold growth.

Frequently Asked Questions (FAQ)

Does this rucksack have an internal metal frame?
No. This is a high-capacity frameless rucksack designed to minimize empty bag weight, offering maximum flexibility and lightweight packing.
Is the backpack completely waterproof?
It is built from water-resistant 900D Oxford fabric, which easily repels rain, snow, and splashes. For prolonged torrential downpours, an external rain cover is recommended.
Can this pack be used as a carry-on for commercial flights?
When fully packed to its 100L capacity, it exceeds standard airline carry-on dimensions. However, because it is frameless, it can be under-packed and compressed to fit tighter spaces if needed.
