Foam density is the hidden spec buyers overlook.
Density grades
- Low density: cheap, compresses fast.
- Mid density: standard for gig bags.
- High density: hard cases and flight cases.
Why it matters
Low-density foam bottoms out on impact. High-density foam absorbs and distributes force.
Checking
Press the lining — it should spring back firmly.
