Ditto to Grizz,
I have two pair of pants on order in two sizes and I will return the one that doesn't fit.
The inventory problem seems related to their business model.
Their low inventories are designed to keep their costs down and their items more reasonably priced. That's a two edged sword, if customers are used to getting what they want, when they want.
Sitka, which also has great products, has taken the high inventory approach, but you pay way more for the convenience of always having things in stock. IMO
