Does every outdoor fabric listing mean the same cloth?
No. Outdoor fabric is cloth for weather, abrasion, or load outside. Rain, sun, and pack wear are different briefs. Name rain, UV, tear, and whether seams will be taped.
Can you skip sampling outdoor fabric?
Test the claim you are buying. Do not invent hydrostatic numbers.
What should stay on the brief besides the keyword outdoor fabric?
Hazard, barrier, mass, and seams. Using dress velvet as outdoor cloth.
