There are a few variants in Manfrotto's Befree carbon fiber travel tripod line. The Befree Advanced adds twist locks and a heavier load rating.
The Manfrotto 190go! M-Series Carbon Fiber Travel Tripod is a 4-section tripod that's rated for a load capacity of about 15 pounds, stands up to 58 inches tall, and weights under 3 pounds. Here's my hands-on review.
The BeFree aims to be lightweight, and lightweight it is. At only 2.4 lbs--and that's including the head--it qualifies as ultralight.
