We’ve been ok with GoVino for picnic style events, although those have been few & far between the last couple of years. I critiqued them some years ago here, but just bought another (colored) 4 pack last week.

Sometimes one can find plastic renditions of regular stems, and those might be better for at home / outside usage; GoVino’s are better for hikes/picnics etc. I have a small six pack of what looks like Riedel Bordeaux shapes (but in plastic) that was picked up from Cost+ World Market some years ago for almost free (coupon+loyalty reward) and their main duty for me me is to be shoved into my ski boots when I travel in the winter.
