How much heavier in winter?

Could anyone give me an indication of how much their Base weight (i.e. exc food, water, fuel, clothes worn) increases for winter?

Say a comparison of what you would take in high summer to this time of year?

I've just totalled up my winter bag and was surprised it was over 2kg heavier and that was  just swopping to a winter sleeping bag, winter waterproofs, extra insulation, gloves etc. I hadnt included the crampons and ice axe yet.

Any ideas?

Thanks

sounds Ok/

even without hardware,

heavier sleeping bag, extra down jacket, fibre pile tent bootees, extra gloves, and hat and another ccf mat add up to about 2kg

I never weigh it.

Apologies for the tecnichal jargon - feels a shite load heavier.

....yes, thats pretty much what i've added - just didnt think it was that much heavier.

Okay thanks then

I find that most of the extra weight for winter is taken up with the clothes I'm wearing, rather than extra (or beefier) things I'm carrying.

Today I just went out for the day to climb Ingleborough with a day sack, but I was wearing proper winter clothes as it was bitterly cold. On reflection, I should have packed an ice axe and crampons, as there was a lot of ice on the paths and it wasn't always possible to find better traction beside the paths either. Still... no-one else I met had ice axe and crampons... and I didn't see anyone taking more than a short slip.

My ice axe and crampons barely add 400g to my kit anyway!

Interesting topic EM - something I never considered before.

A quick total of my winter gear adds approx. 2 kg to the bare minimum for summer. Main factors are larger rucksack and heavier sleeping bag.

For a day walk, extra 1/2kg, spare clothes, hat and gloves, jacket for stops.

 Weekend, 3/5kg more, heavier sleeping bag, cook set, (not always carried in high summer, hot meals and drinks not so important and may need to melt ice/snow to get water). The spare clothes as above.

 Serriadh, Jirishanca is a 32l rucksack, depending on sleeping bag I take, I may have to go up in size, as you say can be a very tight squeeze for an overnighter, or longer.

 Ice axe and 'pons strapped to outside.

Serriadh... you only take a 35lt pack?

I was taking extra kit to tryout/test but my recent trip to Dartmoor my pack looked like this...

For those interested this a 100lt Naos 85 with a Deuter ACT32 attached to the back (100lt is just not enough!) the tent (Alpit Kangri) also attached to the outside. Weight excluding food was.... eeek!

 Edit: sorry just to point out alot of the space is taken up with bulk rather than weight.

Bedders - you got the kitchen sink in there as well ?

I can manage 2 nights in summer with all packed inside a Deuter Futura 32. Spring/Autumn using a Deuter ACT Lite 50+10 and for the weather now (-20°C/snow) use a 65L (can't remember the name)

Bedders,

 Last trip I was on, Wicklow meet 3wks go. I had all the gear I needed for the overnight camp inside the Jirishanca, (32l), apart from 2 small vacumun flacks in side pockets.

 Weight all in 11.5kg

I use a Golite Jam 50 for overnighters which should be fine for winter, for summer i could easily go down to 35-40litres, theres plenty spare space.

It took a fair while for me to get my base weight under 6kg, i was getting worried i was heading back to 10kg again!

Kelvin,

 The specs. I saw for Jiri. on OMM site, says its 32l, but mines an older version, so may not be same sack. Not that I'd reckon a differance of 3l would make much of a differance.

 If I can't fit kit into a Jiri. I'll move up to a Golite Jam. (50l). The only problem with that is I've extra space............  I've to resist the desire to fill that up.

 I've gone a bit lightweight since last time, but still like my comfort, so not too LW. I don't weigh every bit of kit to see what it is in gms. I have got kit lighter and less bulkier than before. I've manged to reduce all in weight by about 3.5kg. of which about half is by using lighter ruksacks.
