Cobra Instructor Sure‑Fit PBI/Lenzing FR® Firefighting Hood


Cobra Instructor hoods offer improved styling for better fit and coverage. Triple ply hood with double layer coverage of neck, upper chest, shoulders and shoulder blades. The tapered back and notched shoulder drape allow bib to lie flat for a more comfortable fit. Flat-stitched seams eliminate bunching and won’t dig into skin. A half inch wide elastic face opening stretches to full 17" to ensure a snug fit around most SCBA masks. UL Classified to NFPA 1971 Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting – Current Edition.

The Sure Difference:

Cobra Sure‑Fit hoods incorporate a 3" wide center panel rather than the traditional center seam, which allows PGI to contour the hood to the shape of the head for improved fit and comfort. Additionally, Cobra Sure‑Fit hoods have a little extra fabric (ease) built into the design which improves the hood’s thermal resistance from flame and heat due to the extra space adding a layer of air between hood and head and reduces the likelihood of the face opening pulling away from the SCBA mask when head is rotated.

Fabric Description:

PBI is an extraordinary fiber that doesn’t burn in air. Blended with Lenzing FR®, this fabric is the most comfortable flame resistant hood fabric on the market.
