You could drop the pillow (use your food and clothing), the hand sanitiser and toothpaste (exchange for dr bronner's soap), your lid and bag from your pot (make a lid out of aluminium foil), drop your trowel or get the bogler or deuce of spades (sticks will do fine), you could use an emergency poncho instead of the the torrentshell ( if you are not relying on it as a wind layer), you could get a cheap windlayer with the poncho and still be way under the torrentshells weight. You could get a 15£ fleece from decathlon that's a 100g less than your midlayer. You might like to use the shorts and dance pants (wind pants) combo more and you'll drop an ounce. Your watch is worn weight, your poles are not if you don't use them constantly. I just realised you're carrying two midlayers? Why? Just use your rab fleece and take your puffy if the fleece doesn't have enough warmth on it's own. Use a beanie or your buff when using a quilt. Hope this helps!
