Many people here (and elsewhere), including me, have used the Sirui T-025X tripod for quite some time. It's probably the lightest and shortest full-size tripod available, and has been liked by hikers for a long time.
I've come across a new option recently. Vanguard released their Veo 3 Go series, and their 235 is a close competitor to the Sirui. A smidge longer and heavier when folded, but very very close. It's interesting because it offers a few extra features lacking on most travel tripods, namely the center column can go down, it can turn into a monopod, it comes with a short center column, a cell phone adapter, spiked feet and even a bluetooth remote for phones.
(My Sirui has a replacement head that's much nicer than the original one, but makes it a bit larger).
I particularly like the head on the Vanguard, the knobs are actually rotating levers, much more precise, and there is no sag. I've played with it for only a short time, but I can say it's a worthwhile alternative.
