I was on a major roadway going about 45mph, and the cross bars popped off my car, causing the kayaks to fly into the road, and scratch up my car. Only drawback is price. Ring on the road trip I am ready! I love the fact that the sole is not covered in fuzzy material. Appena indossate si percepisce subito leccellente qualità dei materiali produttivi, ma lisolamento acustico generato è forse un po estremo. The sound isolation is excellent for the microphone, you dont get any hints of background noise unless its above certain high volume level of sound/noises Etc.

They feel stiffer, after about 1 hour of use my ears feel "full" if that makes any sense. The cross bar used to anchor your legs.
