I have had some pop ups for a “buddy pouch” that goes near where the belt would be (but no belt necessary) and is supposedly great for just phone and keys. I like to take my sunglasses, phone and a sample size sunscreen into the parks but if I want to avoid the bag check I have to get my husband to throw it all into his cargo shorts. Has anyone used these and can you really avoid the bag check with them? And is it a lot like the old fanny packs, which I avoid since I saw pictures of myself wearing one? Thanks.
