A papermaking belt comprising a reinforcing structure and a framework. The reinforcing structure has air permeability not less than 800 cfm and a Fiber Support Index not less than 75. The framework is joined to the reinforcing structure and extends outwardly not more than about 6.5 mils from the reinforcing structure. The framework has deflection conduits dispersed throughout, encompassed by, and isolated one from another by the framework. A paper-contacting surface of the framework comprises a paper-side network which encompasses paper-side openings of the deflection conduits. A substantial portion of each paper-side opening is not less than about 45 mils in each of its dimensions measured in the X-Y plane. A paper web having two regions: an essentially continuous and macroscopically monoplanar network region, and a dome region comprising a plurality of discrete domes encompassed by the network region. The domes are distributed in a non-random, repeating pattern. A substantial portion of each dome is greater than about 45 mils in each of its dimensions measured in the X-Y plane. The density of the network region is greater than the density of the dome region.
