Location - North Cascades
Bag - 30 degree custom Zpacks cuben quilt (15 oz, Gear Swap pick-up.)
Pad - NeoAir X-Lite short (from REI, 8oz).
Back-up Pad - Gossamer Gear Nightlight Torso Pad (from GG, 3.2 oz). This is a multi-use sit pad, pack frame sheet, pad for my legs, and back-up for the inflatable (saved my back once when my old NeoAir failed halfway through a trip. Still had some rough sleep, but was better then nothing).
Down Worn - Goosefeet down balaclava and down booties (balaclava from Zpacks 1.3oz, booties from Gear Swap, 2.4oz).
Cloths Worn - Ibex Woolies Bottoms and Ibex Echo top (from 6pm.com and REI Gear Garage respectively).
Consumables - dark chocolate, cashews, and 2oz or so of hooch (whisky, rum, brandy, etc.). I know the hooch doesn't help with body temperature, but it does help with morale after a long day.
No other down clothing is brought during the summer. I like to hike until late and get going early, so if it is cold it just motivates me to get into my bag sooner or get going faster.
