Satchel, bag, man bag, cross body, murse...whatever you want to call it, it's a bag to carry your stuff in! We all have wallets, sunglasses, phones, keys so it makes sense to have a bag to carry them all in. They're not masculine, they're not feminine, they're unisex, they are simply bags.
They come in different leathers and different colours, you just need to work out which size and configuration works for you. Most have multiple pockets of varying sizes and all have long shoulder straps generally adjustable.
So, get over yourself and get a satchel!
