UK – Temp advice on sleeping bags

Hi Darryl,
maybe 52ish used to be the average min summer temp at sea level, but haven't you noticed how cold it's been this year and last?

In my experience, nighttime UK summer temps can crash at short notice, almost anywhere, due to sea fogs, high altitude (lol) clear skies, temperature inversions in steep valleys etc etc.

At a one oz penalty I'd go with the 5, you can always stick a leg out if you get warm. Then you can have a go at one of my 5oz inflatable quilts for really warm nights.

It depends what part of the UK you will be using it Darryl! It's a lot colder on the Scottish summits than the south coast of England.
I've recently bought a Montbell UL Thermal sheet, and intend to use that backed up with clothing for 'summer' here in Scotland.

Have you weighed it Mike? One of the reports I read had it nearly 3oz over the stated 12oz.

On the Montbell site, the weight is stated as 13.8 ounces.
Mine weighs 370g. (13.05 ounces?)

You'll never fit in one Rog!!

Sounds like you are 3/4oz down on down. :-(

I have a nice 17oz quilt Tim Marshall made me with 6oz of 900 fill down inside. I just arranged to buy an old 600 fill down jacket to top it up to 9oz fill with :-)

That'll make it an oz lighter than a golite ultra 20 long, with about the same amount of down in.

Well I think I am going to go with the #5.

At the moment I have in my possesion 2 x #5 longs that were sent to me in error. I only require standard length. Each bag is 2oz heavier than neccasary and I did want the abilty to put them comfortably inside my already owned standard length #2's

I reckon I got these at a reasonable price so if anyone is interested I can offer them at the price I paid of £150 each. ( I am sure the retailer would pick up the tab of postage and may be a little more too).

However I am really struggling to find #5 standard in UK at all. It seems that the Yen v Pound in recent months has meant the already scarce supply of these bags has dried up.

I am awaiting one contact to come back to me on this otherwise I either need to keep the long #5 or think again. I believe all stock in UK was/is long.

Can any suggest a route for 2 x #5's

ps. Rog I reckon I'll have all Tyvek stock in London by Wednesday. No problem with storage, collect at your leisure. I could very well be interested in your inflatable quilt (2, one for me and another for my young son).

I think the stated weight might include the stuff-sacks, as it is almost on the money if i include them.

Darryl, I understand the ounce counting, but have you considered using the 5's as overbags rather than inside the 2's? I realise they would still be a bit big for use on their own though. If the standards are unobtainable at the moment, I guess you'll have to live with it or sleep hot in the 2's this summer.

I just picked up a fab Marmot 15f winter bag for my lady off U.S. ebay for $119. Weighs 3lb, but the exterior is a well water resistant ripstop. Best of all, it zips to my Western Mountaineering Ultralite perfectly, which will keep us both snug and happy. :-)
