I don't see an end to BPL gear but maybe to some products. BPL seems to have a constantly changing product line. This year it seems to be focused on the Stealth tarp, Hane Rod, Absoraka (sp?) pack and Cocoon clothing since BPL seems to have limited funds to invest in product offerings.
I'd be surprised if they don't do another run of the merino wool stuff at some point relatively soon.
