Mask is made of a comfortable material. Seems to be working/adhering well so far. However, I have found that it does a pretty good job of keeping the drink secure, even over the rough roads I ride on. These slipper are super comfy. One benefit to this design that ear bud companies are always trying to duplicate is a feeling of open sound that these give you. I give stickers out w/ tips to essential workers. All the spice jars were sealed and filled to the top. There is a circular opening on the new topeak rack that allows the user to operate the bracket to attach the seat onto the rack. This keeps them orderly and out of the way. And i don’t have a lot of clothing on it.
