Not really SUL, but here's my favorite gear:
*2004 Kelty Cloud full Spectra pack (less than 2 lbs. when stripped).
Mine's purple/white, just like this one:
*Borde Bomb white gas stove for winter trips (8 oz).
Bought from HikinJim:
*Jetboil Sol for 3 plus season trips (8.5 oz. not including fuel canister).
*Warbonnet Eldorado hammock (12.5 oz. and full bug protection). Only five ever made, and only one in my color of olive green (not Kermit green).
*Custom Tim Marshall/enLightened equipment dog quilt for my best friend.
*Exped Wallcreeper...so darn versatile it ain't funny (35 degrees F rated, 1.15 lbs).
*Custom modded Luxurylite V-Bag. I had Mat at UK Hammocks turn it into a top quilt and add down to it. Went from 2.15 lbs. to 1.8 lbs. AND it's now a true 20 degree quilt!
*Custom Tim Marshall/enLightened equipment synthetic top quilt/ hammock under quilt. This one was just about Tim's first ever made quilts and it's just awesome! Still going strong after 5 years of hard use. Tim even customized it with my trail name "BIGFOOT".
