I recently got a back from Kathmandu and the strap broke off it after one week, they gave me a replacement but the same thing happened a month down the track. i don't think their quality is as good as it was.
I recently had to go on a hiking trip as part of a team building work thing, and i had no idea what i needed. The guys at the store helped me out with clothing plus basic survival stuff. Excellent staff who have good knowledge of their products.
Make sure you are part of the Summit club as you will get huge savings on their clothes - even on top of their sale prices. The puffer jackets are a great investment and well worth waiting til on sale to get at a really good price.
