James I miss the BPL gear shop too, but there are alternatives that are very good.
Quilts – For snythetic quilts companies like Mountain Laurel Designs and Enlightened Equipment have good prodects. Down quilts are made by a number of other companies like Nunatuk.
Packs – Companies like ULA, Gossamer Gear and MLD offer very good packs. For example the Circuit pack is a good alternative to the BPL Absaroka pack.
Tarps – Lots of companies have tarps similar to what BPL used to sell. Again Mountain Laurel Designs, pluse Gossamer Gear, Zpacks etc.
