Mountain Equipment Fireflash Sleeping Bag, Left Zip

The warmest of our lightest bags. Perfect for going fast and light in the mountains.

By utilizing slanted box-wall baffles throughout the entire main body, meaningful weight is removed from the bag's structure. On the inside of the bag the conventional neck collar is replaced by a significantly lighter collar baffle (which also allows higher concentrations of down to be placed within the main body of the bag) and EXL has been added to the top half of the bag to minimize dead air space, reduce drafts and pull fabric away from the down to maximize loft.

One of the lightest downproof fabrics on the planet. Perfect for alpinists and backpackers for whom weight is absolutely critical. Despite being just 26g/m2, the fabric has exceptional tear resistance, giving you peace of mind on longer or more remote trips.

Specifically designed for Extreme Light models, a significantly lighter yet highly thermally efficient replacement for the conventional neck collar. Used in conjunction with our Gemini zip baffle.
