Layering system for Alps (2000-3000 m)

We did that route a while ago (actually, we started with the Tour de Combin and then switched to the WHR). Now, weather changes from year to year so what was ok for me then, might not be now (although we had all kinds of weather including snow),

Footwear seems ok, although I didn't need gaiters.
I didn't have a fleece with me, but I did wore/carried a windshirt.
I see no gloves. Thin ones don't weight much and can add a lot of warmth.

For those WPB-pants: what featurew do you want ?

Hi Woubier,

Thanks for the reply.
Yes, the weather changes, that's why I have some hard time deciding what to get. I'll add my Nike running gloves +pair of nytrile gloves that fit nicely on them.

Are you suggesting to leave fleece at home? What about down sweater?

The only feature of WP/B pants is WPB :)

During the day, I had enough with my T-shirt (and the windshirt). During stops and in camp, I added my MB Thermawrap UL jacket (and sometimes a fleece hat). For me enough, (but my wife calls me a living heater).

For the WPB-pants: long zips or ankle zips ?

Actually, what I forgot to mention is that I'm going to wild camp along the whole route. That means I stop at 9:00 p.m. where I stop. I have 1 hour of day light to setup tent and cook food. I'm ignoring the huts along the trail. So far my plans. So for camp I think I need a little more warm clothes.

Regarding the pants, ankle zips are for venting? Actually I'm not sure what to do. I have never used WPB pants. I want however to keep their weight as low as possible without sacrificing important features. I understand that what is important depends on person. But I have to start somewhere.

Ankle zips are so you can get your pants on and off without taking off your shoes,

"Actually, what I forgot to mention is that I'm going to wild camp along the whole route. That means I stop at 9:00 p.m. where I stop. I have 1 hour of day light to setup tent and cook food.

The problem with that strategy is that you can arrive somewhere at 9:00 pm where you can't camp. So planning is recommended so that you know at a place where you can camp, that there still is or isn't enough time to reach a spot where you certainly can camp.
I plan always and have then fun already. And is that not also the intention of the trip itself ? We camped also and have never slepped indoors. Sometimes on camping grounds in villages. But that had the advantage of being able to go to a restaurant or to buy food for that evening and not having to carry that food.

"Ankle zips are so you can get your pants on and off without taking off your shoes,"
And the long zips can aid in venting. I have those. Certainly not the lightest at 9,8 oz. but for me, weight is only a factor, not THE factor.

Regarding the campsites. I allocate 1 hour to search for suitable place to pitch a tent. I'm not familiar with the route, so maybe this time slot is inappropriate. Should I allocate more time to find a suitable spot?
Where have you camped along the trail? Near huts? Have you camped anywhere between huts? How likely it is to find yourself in place (in hour of walking to either direction) at evening where no suitable spots for pitching tent are available?

Regarding pants, I bought Marmont Essence jacket as a WP/B shells. It weigh 164 gram according to specs (not arrived yet, so had no chance to put in on scales). Is there similar pants of similar material that would be in the same weight range +-?

I'm a bit fanatic about weight because on my training hikes (20km, 1800m elev. gain) I found that saving a kilo is making THAT big difference and I'm going to climb/downhill ALOT. That's why I'm trying to save as much weight as I can, again, without sacrificing functionality.

This is good to know the options you are talking about here. Currently I'm not feeling competent enough to make a decision.

Thanks, Greg.

First, remember we started doing part of another tour and we came on the WHR-trail only
at the Lac Louvie.
Now, we bivouaced on the border of Lac Louvie (on the opposite site of the lake is a hut), a plateau 10 min. above and before the Cab. de Prafleuri, near Lac de Moiry coming from the Col de Torrent, 10 min. before Meiden in a pasture and on the Europa-trail 10 min. before the Europa hütte, near a bench.
Camping in villages in Arolla, Les Haudères, Zinal and Grächen.
The spot on the Europa-trail was till then in hours the only place suitable for our tent. The second hardest part was the day between Lac Louvie and the Cab. de Prafleuri.
