Vaude Lasona is a slick waterproof and roomy high-tech backpack that has all the features you will need if you are heading out into the hills for the day, but the style you'd expect if you are going to throw it over your shoulders as you head into town! So, why is it so good?! To start, it's very waterproof - Vaude combines different thermal seam closure technologies such as Ultrasonic Welding, High Frequency Welding or Heat Transfer in the construction of the ""Lasona 25"". Contrary to the classic seam closure methods using needle and thread, these modern methods bond the materials together using molecular processes such as ultrasound, heat or pressure. Vaude is the first manufacturer to apply ultrasonic technology in its backpack production and so sets new standards in the manufacturing of mountain sports equipment and has managed to create a pack that is just so much more better in wet weather - no more soggy clothers, papers or sandwiches!
Materials are fused together using ultrasonic energy which generates vibrations that melt materials seamlessly together at temperatures above 250° Celsius. In contrast to other welding methods, ultrasonic technology allows three dimensional processing, opening up unlimited design potential.
Seams manufactured using Ultra Seam Tech offer a number of significant advantages: these seamless material transitions are absolutely waterproof, exceptionally durable, weigh less, and are very comfortable due to the fact that they are absolutely flat and so prevent any possible chafing.
