Tech Tuesday- Ultrasonic Welding

Our ski jackets and pants are waterproof thanks in part to Dermizax. Another ingredient to the waterproof recipe is seam sealing. Where ever stitches are made they need to be seam sealed to ensure that the jacket does not leak.

Instead of stitching, on some of our jackets we use a method called ultrasonic welding. Essentially, a high velocity wheel bonds the pieces of the jackets together with out any stitches. It creates a very strong, clean, and waterproof seam. We also use it in the collar of a number of our jackets for design detail. Below is an example of an ultrasonic welder in action.

For our men's and ladies PRIME jacket- a 4-way stretch, 800 fill down waterproof jacket- we used ultrasonic welding to form the baffles of the jacket. On the jacket these baffles are curved, which is technically very difficult to keep the seams flat.

The Rolls Royce RR4

Yesterday the Telegraph had a story on the new Rolls Royce RR4. The listed some minor details on the car and posted the image above. At first glance it is quite a departure from what is traditionally expected from Rolls Royce. But if you actually look closer you can see details that are inherently Rolls. Ian Cameron, the chief designer, said:

"The RR4 has a more informal presence than the Phantom, with a greater emphasis on driving. This is expressed through its slightly smaller dimensions and more organic form, yet with powerful, purposeful proportions. It is a true and uncompromising Rolls-Royce in every sense."

Looking over our 08/09 collection that will be out this fall, there are some pieces that might not be immediately recognizable as "KJUS". But as Mr. Cameron suggested about the RR4- they are true and uncompromising KJUS in every sense.

And like the RR4 sketch above sometimes it's hard to tell in reality what it'll actually look like-

According to Edmunds.com the RR4 will be priced between $250,000 and $280,000 and will be available in 2010. The men's Prime, a 4-way stretch down jacket with 4-way stretch lining and ultrasonic welded baffles will retail for $1,790 and be available in October of this year.
