Two gig bags can both say “10mm padding” and protect differently, because foam density varies a lot. Here is what actually matters.
Foam Density vs Thickness
Thick, soft foam absorbs a slow squeeze; dense foam absorbs a drop. The best electric gig bags combine both: a dense impact layer (high-density PE or EVA foam) at the face, corners and bottom, with a soft comfort layer inside for the finish.
Neck Support
Electric guitar necks are vulnerable at the headstock. Look for a raised neck pocket or adjustable neck rest that holds the headstock off the bottom of the bag, and padding thick enough that the neck cannot flex sideways in transit.
Impact Zones
Check the bottom (most bags land there first), the face (lid), and the headstock area. A bag with uniform padding everywhere protects nowhere especially. Premium bags concentrate material at these zones.
What to Check Before Buying
- Density of the face padding, not just the label thickness.
- Neck pocket height relative to your guitar’s headstock.
- Strap attachment points — reinforced where backpack straps meet the body.
- Zipper quality at stress points.
