Professional hiking, I use Ferrino and Vaude. The Ferrino are better perceived by professional but I much prefer the much simpler because Vaude to mount, better tarpaulin stretched over pro appearance and color more pep. Here the model riding the biggest XT. The filled bag is shorter than expected, it is 62 cm long and about 7 kg. Unlike other Campo, XT can store the material in the entrance. I highly recommend taking the additional floor protection. Ideal for family rides in the base camps.
