Emergency kit is a tricky thing. It’s like an insurance policy – you’re spending money on something you hope never to have to use. But I’ve spent enough time in the hills to know that accidents can happen however prepared you may be. And come the day that you do need it, you’ll be really glad you spent an extra few pounds on a product that could, quite literally, save your life.
For years, the traditional foil survival blanket filled the role of emergency protection against the weather or at least tried to. Foil blankets are all very well when it’s a reasonably warm, calm day. But on a rain-lashed mountainside, they’re about as much use as a toothpick on an ice field. And the good old law of sod says, that if you’re ever going to need an emergency bivvy, it’s not going to be on a beautiful summer’s day.
That’s where the SOL Emergency Bivvy comes in. It’s not much bigger or heavier than a foil survival blanket, but it has a much higher chance of keeping you warm and dry. A foil blanket is unlikely to save your life – this piece of kit could.
The SOL Emergency Bivvy
I bought the SOL Emergency Bivvy some years back when I was after a super-lightweight emergency bag for running mountain marathons. Even I, trying to get my pack weight down as much as possible, couldn’t begrudge the tiny 3.8oz weight. It has been my constant companion since; happily snuggled at the bottom of my rucksack ready for the day it will be needed.
The SOL Emergency Bivvy pretty much does what it says on the tin. Unlike other SOL bivvy bags which are designed to be used instead of a sleeping bag, this is very much a keep-you-alive, last resort option. So don’t expect to get a good night’s sleep if you’re using it on its own. (Respect to Tom and Craig from Hikeordie, who slept in a field for four days as part of their test.)
SOL Emergency Bivvy specifications
The SOL Bivvy works by reflecting your body heat – up to 90 percent according to the manufacturer, though it’s a bit unclear as to how this is measured. The outside of the bag is a bright, ‘help me’ shade of orange, which will come in handy if you’re awaiting rescue, though not if you’re stealth bivvying in a farmer’s field.
The bag is made from polyethylene, which has some stretch, so unlike your foil blanket, it shouldn’t rip when you’re getting in and out. With seam-sealed edges, it’s completely waterproof and windproof, but bear in mind it’s not breathable. If you’re wrapped up in it for a while, you’re likely to get some condensation inside.
Unwrapped, it’s 84 inches in length, long enough to be pulled over the head of even a tall person (for evidence of this, check out this video). It’s also pretty wide, so if you’re skinny you could probably fit two of you in it to help keep warm. (No, I’m not kidding – sharing body heat is a tried and tested strategy for warding off hypothermia. Choose your hiking companions wisely!)
Often emergency survival kit is designed to be single use. If you’ve ever tried to fold a foil survival blanket back up, you’ll know that it’s an exercise in frustration. Fortunately, the designers of the SOL Bivvy took this into consideration. The bivvy comes with a nice stuff sack that’s twice as large as the rolled-up bivvy. While it does take about ten minutes to get it rolled up tight, it will fit back in the stuff sack after use.
What to use it for
Although it’s termed a ‘bivvy’, the SOL Emergency Bivvy is not intended to be used as a regular bivy sack. If you’re after something to use for lightweight bivvies on a planned basis, check out the SOL Thermal or Escape Bivvy. But as an emergency piece of kit, it beats the old foil blanket hands down, and at £17, it’s an insurance policy you can’t afford not to take.
