My kudo's go to Bonatti key lock biners. They are quick clips for those manky 1/4 antique bolts still found out there in the desert SW and other remote areas. Modern biners have too big of a lip flare to go through easily. They also double as my racking biners for wired nuts. Without the notch, the wires come off easily. Downside is that they flex a lot when bounce testing a piece...
CRAZY CREEK CHAIR! It absoloutly rocks On multiday NW or AK alpine climbs. storm bound in a tent or cooking it's the ultimate luxury piece. It doubles as my sleeping pad in the summer. On snow, I use it in conjunction with a 3/4 ultralight thermorest for the above the waist insulation/padding and lay out the flattened Crazy Creek for foot/thigh insulation. Placed against my back inside a pack or haul bag, alleviates lacerated kidneys from pins and cams. Adds support/padding in my Sea Kayak after the salt water has me a bit chafed.
Patagucci Puffball. Lighter, warmer and WAAY more compressible than fleece, Great windshirt, quick drying. Not recommended for chimneys.
Last and not least, my REI handkerchief with pictures of knots on it. Entertaining instruction when tentbound. Snot rag, tourniquet, pot holder, do rag, shoulder padding against straps, neck protection against the sun, washcloth, gag for unusually chatty partners...
