Many carriers are sized for 40 oz tumblers, and some crossbody slings list compatibility across a 16–40 oz range.
Adjustability varies by model: some neoprene carriers list a shoulder strap range of about 27.5" to 50", while other listings give an adjustable range of roughly 75 cm to 134 cm.
Common attachment methods include hook-and-loop closures, drawstring closures that hold bottles snugly, and accessories like carabiner clips for carrying small items.
Care guidance varies, but common instructions are to spot-clean or wipe down polyester/PE slings. Product descriptions frequently note the fabrics are easy to clean.
Adjustable and detachable straps let carriers be worn crossbody, over one shoulder, as a sling, or carried by hand; some listings also describe using them like small messenger bags or handbags.
Common extras include phone or zippered pockets, straw covers, carabiner clips, and slip-in side pockets for small items.
