It is nice to be able to post something good about a company or two!
After doing tons of research here on BPL (and elsewhere), I bought a pair of Western Mountaineering Flash Pants from Hermit's Hut in Redding, California. When the pants arrived, they were inventory tagged as size "large" (what I ordered) but they were really size "medium" -- too small.
I called Hermit's Hut and spoke to Clarence. I explained what happened and that I was headed out on a trip and needed a replacement pair of pants ASAP. Clarence walked me through the entire process and got Western Mountaineering to ship me a replacement pair of the correct size via overnight delivery.
The pants arrived, the trip was saved, and all is well.
Both companies did a great job and I would not hesitate to recommend them!
