In reply to Mr Fuller:
As a student it would be worth a visit just to take in the amount of different product out there.
All the main textile companies will be there but it may be difficult for you to get a chance to speak to them as they will be doing business with all the major outdoor manufactures and designers.
The smaller comapnies may take the time and sit with you, but if it is an indepth tech talk you are looking for, you may be a bit disapointed. You will of course see all the latest fabrics and the sales folks will be happy to talk about how these work and function.
Oh and if you do go make it a 2/3 day trip there is loads going on and munich is a great city.
