There’s no wonder it’s often used by the US military – not bad for a company from Yorkshire in the UK!

I would recommend this or some other UL trekking pole tent (Durston X Mid gets good reviews, but there are many options). The top layer material is unfortunately not breathable and so condensation is likely to be a bit of an issue – it should be noted though that we have not found a single bivvi bag which does not suffer from this problem slightly if fully done up and you’re inside breathing all night. For positioning your bivvy bag, it’s best to aim for flat ground away from any precarious drops – you might be a ‘sleep-roller’ and roll off the cliff!

When the Hawk is fully rolled out, it’s spacious enough to house a sleeping bag and mat or self-inflating mattress inside. Any more than this and the lack of breathability may cause too much condensation and dampness, with no easy way of drying out.

The Highlander Hawk bivi bag packs into a tiny 37 x 12cm ripstop stuff sack, making it brilliant for all kinds of adventures.The 103 third parties who use cookies on this service do so for their purposes of displaying and measuring personalized ads, generating audience insights, and developing and improving products. It uses a weft of thick and thin fibers which are arranged to allow moisture from your sweat and breath to breathe out through the mesh whilst also being fully waterproof and windproof to rain and water trying to get in from the outside. Bivvy bags range from emergency metal foil space blankets which every hill climber and mountaineer should keep in their rucksack, to full-on tent replacements costing hundreds of pounds. They are very lightweight, but it must be said that the total combined weight of the bivvy is not the lowest at 1. I am actually not that experienced with how to approach airing a tent in a cramped urban hostel, maybe there is some practical advice you can give.
