My normal pack weight including food and water is around 15kg to 20kg but this is when I'm normally walking with the missus and I usually carry all our food, jetboil sumo with fuel canisters, mine and her tent (she has a MSR Hubba Hubba) and the good stuff (wine and whisky).
I'm not a warm weather walker. I like the colder and wet climate so it generally does mean more weight but I would also like to shave off more when walking from hut-to-hut when I'm in NZ and when I do 3 Capes in October this year.
My current gear list as it stands:
Sea To Summit Duo - it's light but terrible in wet weather conditions. Including UL tarp it totals 1681g with the groundsheet
Mountain Designs Travelite 330 - not good but I've had it for quite a few years when I got it on special. Never weighed it but MD website says 920g
Lowe Alpine TFX Cerro Torre 65:85 Backpack -2720g
The North Face Aconcagua down jacket - 513g
Sea To Summit Poncho - It doesn't breathe but it does the job. 230g
Mountain Designs Sleeping Mat - 680g
Ideally...what I want to do is cram as much as I can into my Osprey Manta daypack but I'd be missing out on a lot of creature comforts and then some. So I've been considering the following for future purchase (or already have...well my wife owns - she's a fricken gear junkie).
Tent: I'll keep the Duo for now but so tempted to borrow my wifes Hubba Hubba or buy a Hilleberg Soulo 4 season when I'm not going hut-to-hut
Sleeping Bag: Looking at the Sea To Summit Spark SPIII or Exped Comfort 800. TBH...I hate mummy-shaped bags but we're talking weight here. I do like this bag though http://www.paddypallin.com.au/nemo-noct ... 29718.html

BackPack: Osprey Exos 58
Jacket For Warmth: I'm a little torn here. Toss-up between Outdoor Research Floodlight (waterproof with 800+ fill goose down) 600g or The North Face Thermoball 375g
Rain Jacket: Outdoor Research Floodlight (waterproof with 800+ fill goose down) 600g or Arc'teryx Theta AR 485g
Mat: Exped Downmat UL 7 LW 810g
Any recommendations? Just remember, I rarely walk during the warmer climate and do most of my walks during the cooler climate. My normal walking boots are quite heavy too. I mix it up between my Scarpa Kailash or my old SL M3's
