🔥 What is a FireSak?

The FireSak Goliath is simply the largest, meanest battery storage bag on the market. The most heavy-duty FireSak yet — a premium battery storage bag built for bigger setups, tougher use, and a more refined overall design.

It features:

  • Massive new size: 75cm tall, 64cm wide, 35cm front to back.

  • Thicker material throughout for a more rugged, robust feel.

  • VeloFlow: four circular lid vents with silver rings pressed into the top.

  • PyroMesh: a rectangular metal mesh screen sewn into the bag layers.

  • External mesh side pocket for accessory storage.

  • Double-stitched para-aramid fiber thread for reinforced construction.

  • A more premium, more industrial, more serious build than the earlier bags.

This is the FireSak for people who want the biggest option in the lineup and want it to feel like a real upgrade, not just a larger version of the same thing.
