How to carry it
Lid on the pack, mask at the ready
The Brain rides on top of your pack and holds the rest of your quick-grab essentials: your assembled Sundström mask, plus headlamp, batteries, flagging, snacks, and the maps and IAPs in its admin pocket. Take the mask out of its storage tub, assemble it with the filter you need, and stow it in The Brain so it’s on your back and ready the moment smoke lays down. Keep the tub and spare filters and pre-filters in your pack body or rig.

FAQ
Combo questions
Does the mask fit inside The Brain?
The storage tub stays behind, but the mask goes in. Take the mask out of the tub, assemble it with your filter, and stow it in The Brain so it’s ready to grab. Keep the tub and spare filters in your pack body or rig.
Which packs does The Brain fit?
It comes on the Mystery Ranch Hotshot CF and is the replacement lid for the Hotshot. Its Quick Attach buckles plug into Hot Speed and Shift packs. Not sure about yours? Ask us.
Can I choose a different Brain color?
The Brain is currently offered in black only.
Is the mask approved for structural firefighting?
No. It’s an air-purifying respirator for non-IDLH work such as mop-up, overhaul in exterior areas, ash and debris. Use SCBA for interior attack or any IDLH atmosphere.
Can I swap the mask size after I order?
Yes, as long as the mask packaging hasn’t been opened, under our return policy. We can’t accept opened masks, filters or cartridges.
Do you do crew pricing on the combo?
Yes. Tell us your headcount and size mix on the contact page, call 424-388-0493, or email JonGustafson@FastFireNetwork.com.
