Latest update...
I've just finished reading
Beyond Backpacking: Ray Jardine's Guide to Lightweight Hiking and have given serious consideration to making a quilt to his design instead of using a sleeping bag. However, my current thoughts are that the Alpkit Pipedream bags are so light, I'm not convinced that I'd make significant weight savings over even a Jardine quilt (though my mind is not closed to the possibility).
It's funny, but I find that until I actually get around to writing down my specific requirements, my purchasing decision changes on a regular basis. Luckily, the Alpkit waiting list is actually allowing me to sort out what I really want:
- I'd like a bag that I can use as much as possible in the UK in multiple seasons.
- I really don't want to have to use a "Winter" bag as a duvet whenever it gets above freezing (though I'd be perfectly prepared to do so in the Summer, if necessary).
- I want to go as light as possible.
- I don't sleep hot, but probably not too cold either.
- I'm unlikely to travel regularly (if at all) to Scotland when it's really cold, but I want to be able to sleep out in my local woods (Beds/Bucks) in the middle of Winter (-5º to -10º?).
I've emailed Alpkit to see if I can get away with a Pipedream 400, rather than the 600. The 400 is obviously much more of an "all-year-round" bag for the UK and it's weight (750g) is fantastic. Perhaps the current cold snap is weighing on my mind (it has reached -10º where I live this week) and I'd be fine with a 400 plus extra clothes if necessary?
However, another thought I've had is to use a Pipedream 400 with a shaped "duvet" cover (a thinner and lighter version of the
Ray Jardine quilt to extend its temperature range when needed. Something like a lightweight version of the US Army sleeping system.
Incidentally, I highly recommend Ray Jardine's book (he has a newer book,
Trail Life: Ray Jardine's Lightweight Backpacking, which supercedes the one linked to above). Although he is pretty hardcore when it comes to lightweight hiking, his ideas are very thought provoking and that's a good thing, even if I don't think they are all directly transferrable to non-hiking activities such as bushcraft.
