WATER PROOF CORDURA 305D BACK PACK/BLACK
water-proof-cordura-305d-back-pack-black
This bag is crafted from CORDURA® 305d fabric, known for its excellent strength against friction, tearing, and abrasion.
It features L-VENT processing (3 layers) on the inside, providing a breathable waterproof material with a water pressure resistance of over 20,000mm. This ensures it allows water vapor to escape while keeping rain and wind out.
The front pocket and side zip pockets are taped for seams, preventing water from seeping in through sewn areas.
The back layer offers a storage space for a PC or similar devices inside the bag, utilizing a soft material and thick cushioning to securely protect your electronics.
Shoulder pads (harness) are equipped with cushioning, and stretch materials are used on the back side to reduce pressure on the shoulders during use.
Note: While the main material is treated with a waterproof 3-layer fabric, water may still enter through non-taped stitched areas.
