Couldn't wade through the whole thread but my quick 2 cents on Arcteryx is this.
1. Their customer service sucks. Trying to get a return call, even on a bulk order, is painful. For this reason alone our SAR group almost walked away from ever doing business with them.
2. I own a pair of their Theta AR pants and a Bora 80 pack. The pants are so well made, relatively compact and multifunctional that I smile every time I put them on. They have over 100 hard bush wacking days on them and still clean up almost new. The pack has yet to be fully tested but I am pretty confident I will be happy with it.
3. The retail price for Arcteryx is ridiculous. I am on the pro-plan and it barely makes the prices competitive with MHW and other brands I have had positive experiences with. Without the discount there is no way I could justify it. MHW is doing great stuff for great prices.
Finally, one more plug for the Theta pants....truly exceptional!
