Luvs lists sizes from Newborn through Size 8 with the following approximate weight ranges: Newborn (<10 lb), Size 1 (8–14 lb), Size 2 (12–18 lb), Size 3 (16–28 lb), Size 4 (22–37 lb), Size 5 (27+ lb), Size 6 (35+ lb), Size 7 (41+ lb), and Size 8 (46+ lb). Weight ranges are approximate and can overlap between sizes.
Luvs advertises multiple protection features, typically described as four levels of protection: Triple Leakguards, a wetness indicator, stretchy/secure side panels, and leak-barrier cuffs. Product details also reference absorbent layers and leak guards that work together to help prevent leaks.
Materials shown in the product details vary by style, but examples listed across results include polypropylene, spandex, and polyester. Specific materials can differ by product version.
Product descriptions note that some Luvs diapers are dermatologically tested and marketed as hypoallergenic. They are listed as paraben-free and latex-free, and some variants include aloe.
The wetness indicator changes color (turns blue on contact with wetness) to show when the diaper is wet.
Product details instruct that Luvs diapers should not be flushed.
