Surplus Brit Army bashas seem to finally be getting cheaper over here.

The weight is right, and since (from bad experience) I'm a long-time devotee of being as inconspicuous in the woods as possible, I find them interesting but... I can't help but recall that I have a Brit Army surplus DPM rain jacket that is apparently nylon waterproofed with rather heavy PVC, and the last time I pulled it out to use it, during Isabel, I found to my dismay that the plasticizer has apparently leeched out of the PVC, making the inside an unwearably sticky mess. Flexible PVC is known for doing this as it ages- as owners of heavy, waterproof gear, even up to inflatable watercraft, know well. The plasticizer won't wash off, and no cleaning products I've tried affect it at all- looks like I'll have to chuck it.

I have no desire to repeat this with another piece of equipment, so- anyone know for sure what the basha is waterproofed wtih? Anyone have experience with one getting sticky, or know for sure that they won't? Thanks in advance.
