For High-Tenacity Fibers, check the blue Duffel in the Hajin City barber shop at F8, or the rooftop of La Grande Vie in Songdo Wharf at H7. These are search locations, with changing loot between deployments. Finding the building does not guarantee a fiber drop.
High-Tenacity Fibers are 3D Printer Ingredients. Keep them intact for recipes such as the Durable Gas Mask and Large Scavenger Backpack rather than treating them as one of the four basic crafting resources.
The Hajin City barber shop at F8
The barber shop is south of Wolves Stadium and Hajin River Heights, close to the road by the river's southern bank. Your compass should identify the area as Hajin City. The All Things How location guide describes green walls, dark wood panels, barber chairs, and sinks beneath a long mirror.
- Reach grid F8 and identify the barber shop by its interior.
- Move to the back corner of the shop.
- Search the blue Duffel on the floor beside the dark bench seat.
- Check the pickup name for High-Tenacity Fibers and keep the ingredient for extraction.
Hajin River Heights is a landmark north of the F8 shop, not the loot container. Image: Activision, via All Things How.
The River Heights landmark helps orient the search; it is north of the barber shop. The pictured landmark is not the fiber container itself. If the Duffel is empty or contains different loot, move on rather than repeatedly searching the same already-opened bag.
Other reported places to check
| Location | What to search | Reason to choose it |
|---|---|---|
| La Grande Vie, Songdo Wharf, H7 | Rooftop shelves, tables, and military lockers | Useful if you deploy near the southeast; two video guides independently show the rooftop route |
| Chang-san Air Base, B5 | Armory and barracks military containers | An alternative when your squad is already equipped for the airbase |
| Military compounds | Military weapon lockers | Additional checks along an existing route rather than a guaranteed farming loop |
For the Songdo Wharf rooftop, the recorded route takes the building's rear elevator to its upper floor, then continues around to another stairway leading onto the roof. Search the sheltered shelves and lockers as well as loose items. The footage guide explicitly includes runs where the rooftop has none, despite recommending the location.
The airbase has greater combat risk. Going there solely for one ingredient is a different decision from searching it while completing another objective. None of these sources provides measured drop rates, so compare travel and combat cost rather than expecting a particular number per run.
Keeping fibers for the right recipe
At the FOB, select the item you intend to print and check its current ingredient list before deploying. Pin the missing ingredient so it is marked while looting. The official crafting guide distinguishes intact ingredients from Synthetics, Electronics, Chemicals, and Metals, and explains that recipes and printer upgrades control what you can produce.
Finding fibers is only one part of crafting. You still need the recipe, the other listed materials, and the necessary printer capability. If the desired recipe remains locked, collecting more fibers alone will not unlock it. A backpack with a suitable secure slot can protect valuable ingredients against a failed extraction; check its available slots before committing to a longer run.
