Mountain Equipment Fireflash Sleeping Bag - Regular Left Zip

Season:EOL

Brand:Mountain Equipment

Code:6000919

The warmest in Mountain Equipment’s Extreme Light range of sleeping bags. The Fireflash is aimed at users who are looking for a very light bag for trekking, mountaineering, climbing or summer alpinism. With Mountain Equipment’s Good Night’s Sleep Temperature rating of -14°C/7°F, the Fireflash is the ideal weight for Spring and Autumn use at valley level or at higher elevations during summer months.

The Fireflash features Plasma outer, 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.

Featuring Mountain Equipment’s very best Eastern European goose down which is sourced from Western Russia, with an actual minimum down cluster content of 93%* & individually tested to ensure a minimum fill power of 800 cubic inches & DOWN Codex approved.

The Fireflash utilises 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 pulls the fabric away from the down to maximize the loft.

The Fireflash is a very well designed sleeping bag full of technology that every mountain user will fully appreciate.

  • Plasma™ 10D outer shell is incredibly light and exceptionally breathable
  • 650g of 90-10 Russian Goose Down with a minimum fill power of 800

Buyers Guide - How to choose a sleeping bag

A good night’s sleep is key to enjoying your time in the hills and vital for physical and mental recovery. Keeping toasty while you sleep is important because your body will naturally drop in temperature during deep rest. There are a multitude of sleeping bags available out there covering a vast price range but if you choose wisely, maintain your bag and store it correctly it could very well keep you snoozing happily for 20+ years.

Choosing the right sleeping bag for you involves asking some key questions included below. To help you understand why they are important simply click through to our full buyers guide to read about the incredible technologies, science, testing and the design involved in getting you a good nights sleep....

- Synthetic or down?

- Men’s or women’s?
- What is a "season" and why do the prices vary so much?
- How do I make sense of comfort ratings?
- Why should a bag “fit” me?
- So do I get what I pay for?
- I brought a “warm” bag but I’m still cold at night.
- What about the environment?




Top tips to make the right choice:

If you can visit the shop to look at them in person this is ideal as not only does it allow you to place bags side by side to instantly see the difference in cut and loft but it also gives you the opportunity to try the bags on. Just like clothing, they are all cut differently and often come in length options so that you can get exactly the right fit for you. These days, however, travelling long distances and meeting face to face may not be quite so straightforward so we are more than happy to talk with you over the phone to discuss which sleeping bag may work best for you. We are all active users of the equipment we sell and we have all had our fair share of miserable nights, that’s why we are all happy to share our knowledge - so that you don’t have to!
