In reply to G4ISJ:
I see survival shelters which look to fit the bill
and weighing less than 500gms look ideal, but I wonder how functional
they would actually be.
Pete, having carried our Terra Nova 2 Bothy bag up many hills since we started SOTA, we decided to try it out in gales and horizontal rain on Skiddaw a couple of weeks ago. It made what would have been a cold wet miserable activation quite fun - I suspect it would have been a very rapid activation using the handhelds without our shelter. A 2006 video by Richard G3CWI gives a pretty good impression of our experience!
A 2-man is a rather tight fit for a 6ft 2in and 5ft 4in couple with kit - however one at a time we did just manage to take off our jackets, add a fleece and put jackets back on (I’m sure this would have made an hilarious video from the outside). It certainly warmed up quickly. The noise inside made it quite difficult for both of us to hear the radio but interestingly it couldn’t be heard at all by our chasers.
We would definitely use a bothy bag again in the future if required. A larger one would have been easier for 2 people in some ways but
a) it would not have been as warm
b) I doubt we’d have been able to keep it down, even using our rucksacks, in the high winds. However, we also have a 4 man so will try that sometime. A 2.5 or 3 man would be ideal for 2! (Checking dimensions for the 2/3 man in different makes, I can’t see any particular one looking significantly larger).
I can certainly think of some past activations when the Bothy bag would have been better over us than inside the rucksack! Well worth carrying weight wise as an emergency item anyway.
