Another piece of gear that you don’t want to use but ought to carry. These tough plastic bivvy bags have often been derided as “Orange Fertiliser Bags”, but have probably saved more lives than any other single piece of walking kit. Although heavier and bulkier than the silvered Emergency Blankets they have the advantage that they can be used again & again, so whether you want to bivvy overnight on Helvellyn to see the sunrise or just want something in case of emergencies these will fit the bill. Bright orange for high visibility even in bad weather and useful survival tips printed on the bag. Size: 180 x 90cm. Weight: 230g.
