The Blizzard Survival Bag is a full-sized sleeping bag in a pack the size of a video cassette, providing total warmth and shelter - anywhere, at any time.
It's made from the unique Reflexcell™ material, which blocks heat loss more effectively than any other emergency product. The bag also contains elastic, causing it to hug the body, giving a great feeling of warmth and security.

APPLICATIONS
Blizzard Survival bags are increasingly being chosen as standard equipment by the military, emergency services, civil emergency planners, medical authorities and rescue teams.
Outdoor Sports
Many walkers, climbers, cavers, canoeists, mountain rescue teams, ski mountaineers, adventure racers and others carry the bag as a safety product.
Motoring & Working Outdoors
The Blizzard Survival Bag is an excellent piece of personal safety equipment for motorists and workers who may be stranded in remote locations and during severe weather.
Planned Bivouacs
The Blizzard Survival Bag is the lightest, most compact option for planned bivouacs whilst backpacking, mountaineering, caving, adventure racing etc.
Emergency Preparedness
The Blizzard Survival Bag is a revolution in thermal protection for any situation in which people need to be kept warm, or treated immediately for chilling and hypothermia. Applications include everything from military, medical, marine and mountain rescue, to civil evacuations and disasters.
Military
Now being recommended as standard issue or in kit form.
Hot Tips
If the foot end of the bag is cut open, the wearer can be protected yet remain able to walk (the stretch material allows leg movement, and allows hands to be extended for protection in the event of a slip).
When you get home, a vacuum cleaner will enable you to re-pack a used Blizzard Survival Bag to a very small size.
Reflexcell™
The following is some of the information about Reflexcell presented on Blizzard Survival’s own website:
‘Reflexcell™ products are totally unique: weight-for-weight far warmer than goose down, yet 100% weatherproof, tough, ultra-portable and re-usable.
Because Reflexcell™ is so different from any other material, many of the usual rules just don’t apply, so to get the most out of our products, please read these instructions carefully.
When Reflexcell™ products are packed in our factory, they are neatly folded and all air removed to give an exceptionally small package. Occasionally a small puncture in the outer packaging may occur, making the pack feel softer, and have a slightly more rounded appearance. This in no way affects the performance of the products, and should not be viewed as a problem.
If you are lying on the ground, providing extra insulation between the Reflexcell™ material and the ground will make you much warmer, for example a sleeping mat, a rucksack, or a pile of vegetation.
Reflexcell™, the base material for Blizzard’s unique products, has major advantages over existing materials and is revolutionising emergency thermal protection. Reflexcell™ took fifteen years to develop and is completely different from other reflective blanket materials.
Reflexcell™ has a cellular construction to trap warm air, elastication which draws the material to the body, reducing cold spaces and heat loss by convection, and finally, silvered surfaces to block heat loss by radiation. It is also completely waterproof and windproof.
This unique combination gives Reflexcell™ vastly superior warmth to any comparable emergency product. However its greatest strength is that it can be compressed into the tiniest of packages and stored indefinitely without damaging its performance.
What makes Blizzard's Reflexcell™ products so warm?
- The cells in the material trap warm, still air, providing insulation.
- The silver reflective surfaces block radiated heat.
- The elastic causes the material to hug the body, stopping drafts, reducing convection, and keeping the material right next to you where it is needed.
- The outer layer is completely waterproof and windproof.
- Unlike most other insulating materials, ours works just as well when wet.
What is the coldest temperature at which Reflexcell™ products will be warm enough?
That depends on many factors:
- The individual’s ability to tolerate cold.
- The amount of other clothing worn.
- Wind-chill.
- Duration of exposure.
- Insulation from the ground.
As a rough guide, if you are wearing the type of clothes appropriate for the season and you make some effort to find a sheltered spot and put some insulation underneath you, then in spring, summer and autumn you should be warm and comfortable. In winter you may not be so comfortable, but you should be able to survive for several days in all but the most extreme conditions.
How strong is Reflexcell™ material?
Surprisingly strong. Single layer reflective blankets are very fragile because they are easily punctured, and once a tear has started to develop, it rips right across the material. This doesn’t happen to Reflexcell™ material because:
- The three layers reinforce each other, and even if one is damaged, the others usually remain intact.
- The seams in the material act like the thick threads in ripstop nylon, stopping tears from developing.
- Materials only tear when they are pulled tight. The elastic in the Reflexcell™ material helps to keep the material in a relaxed state – if it doesn’t get pulled tight, it doesn’t tear.
Of course the material can be damaged (it should be kept away from sharp objects) but even if this happens, it will continue to keep you warm.
Don’t reflective products reflect the cold back to you?
Technically the answer is no. Physicists tell us that whereas radiated heat can be reflected, cold cannot. It is true that if the surface of your body is cold, it will emit very little radiated heat, so that reflecting this back to you will only make a very small difference to getting you warmer. But it is scientifically impossible for a material to reflect cold back to you and make you colder.
Fortunately, unlike other reflective products, most of Reflexcell™’s warming ability comes from trapped air insulation, so even when there is very little effect from the reflectiveness of the material, this insulation will help you to get warm much faster than other reflective products.
Are Reflexcell™ products expensive?
If you compare Reflexcell™ products with single skin products, for example with polythene survival bags, or with space blankets, they might not look cheap. But they are actually a completely different type of product – equivalent to a traditional “bivvi bag” and a conventional insulating sleeping bag in one package. Polythene survival bags may protect you from the worst of the weather, but you will usually be cold, damp and uncomfortable. In cold conditions they will not stop you becoming hypothermic.
People who have used single layer reflective blankets in any but the most gentle conditions report disastrous results – blankets disintegrating when unpacked, ripping in the wind, and not even offering the illusion of warmth. Compare this with a product which will give you a comfortable night, even in cold conditions, which in a real emergency will keep you alive for a week, which will provide instant warmth and shelter and protect against hypothermia even if you are wet through.
Do you get condensation inside Reflexcell™ products?
Not normally. This is because the warmth of the material suppresses the formation of condensation, and the perforations in the inner and middle layers allow much of the moisture to move away from the body. However under certain conditions small amounts of moisture can form. No one who has used Reflexcell™ products has felt that these caused any problem, or affected the performance of the material.’
