Might be of use to pass this link along to the Board. Several of us around here now are using these for our tastings. Where they shine best is for Champagne as they are big enough in width to cover and hold the large glass bottles. They work less well for still wine.
I like the stretchy lycra sleves sold by Vins Rare.
Those are neat!
My own easy-ish method is to pour the contents of a blind bottle into a used screwcap bottle and then put the cap back on tightly and bring the “faux” bottle to the tasting. It’s interesting how the label on the bottle sometimes gets into people’s heads about their guess on the wine!
Cool. Not seen these before. At least now it seems there are options to sufficiently cloak bottles from Vilmart, etc that have a large base. For so long a # of us tried to force stuff into Bordeaux-like bags and then wonder why they were always ripping at the seams.
At the other end of the spectrum from the ones in Frank’s OP, this is the set I’ve bought twice now and used a ton. These don’t fit around your wider Champagne bottles, but fit most everything else and have a nice velcro closure.
I recall the price being a decent amount lower than this when I bought them before, though.

I was talking to a friend a while back that remarked a bunch of his wine friends in China save up the glass Voss water bottles to use as decanters for blind wines.
So fancy you guys are!
I just double-bag each bottle with brown paper lunch bags and secure with a trimmed zip tie at the neck!
A friend in my Bordeaux group has a set of burlap bags with ties each with a blank patch on it. Great thing is when we are doing a blind tasting we are each handed a bag, and after everyone has bagged their wine we switch them around and then randomly number with dry erase. Similar to bags in original link, but you don’t even know which is your bag.
My local group folks just bag their own (paper bag, foil, sock puppets) but in that theme we want owner to answer questions as we guess.
