Sleeping bag for Bivvy
« on: September 25, 2018, 12:31:54 pm »
What sleeping bag do TCR bivvyists use?
Should I opt for down (warm and compact) or manmade (less susceptible to damp/condensation but more bulky)?

(Tried asking this on TCR facebook and being mocked.... somewhere between "I slept in a crisp packet" and "Sleep, Wozzat?"  :)

Synthetic.

I got an As-tucas Sestrels quilt just for ultra racing. It weighs about the same as my (warmer) down bag, but it is a lot more durable in terms of moisture, and pack abuse. I have a sea to summit event compression dry sack so I can make it even more tiny.

I am not a particularly experience ultra racer, so I may be Doing It Wrong™, but it's what I went for. I have considered using the sestrels poncho from As-tucas for next years TCR If I get in. But I'm undecided.

Two comments;

Nunatak Gear in the USA makes an interesting looking range of bivi gear. They use Climashield (as does As Tucas). Looking at the website might help you focus your thoughts. 

The Sestrals Poncho is very tempting!

That quilt has me thinking of two options:
Read "for whom the bell tolls" and figure out what it is that Robert carries to sleep in;
Or Ride in a Kilt; that's not the Walter Scott fabrication type of kilt, but a proper one, that's basically just a big quilt that you could lob in the heather at the end of the day and then roll yourself up in to sleep.

They are all of course variations on the same concept!

I'm not racing, but when I bring a bivvy on an audax ride it usually is with a quilt made by Mountain laurel designs with ClimaShield Apex isolation (the lightest 2oz/yrd variant). It packs surprisingly small.
