Bags now are mainly for storage while the old ones used to say to clean your lenses only with bag provided. The new ones merely wipe fingerprint and skin oils all over, rather than remove. I keep a high grade fine micrfiber towel in my car just for cleaning my lenses since I can't count on the Oak bags. The weight is night and day different too. I will have to drag out my little scale and weigh the original grey bag (full size) vs the black (with grey striped tag) vs the black (hdo lil tag) and see what the results are. I think they stopped making bags that say "plutonite lens should only be cleaned with provided sunglass bag" on the grey striped tag bags as well. I have a red one that has that on the tag right in front of me.
