Leaking is when a few drops of urine are released inadvertently from your bladder. Urinating is when you release your full bladder of urine.

UltiUndies currently has one absorbency level — up to 4 tsps of leakproof protection!

Our undies are very comfortable. You may use UltiUndies all day, 24/7. You can use our undies with your period as extra leak protection. Do not use UltiUndies if you cannot control your bladder and urinate fully. ULTIUNDIES ARE NOT A REPLACEMENT FOR DIAPERS, PADS, OR TAMPONS.

Our leakproof undies feature a triple layer technology that ensures you stay fresh, dry and protected. The UltiUndies gusset or crotch (part of undies between the legs) is made up of three layers of fabrics: (1) the anti-odor top layer wicks away moisture from your skin and keeps you dry; (2) the middle layer retains your leak and does not allow it to seep thru to the third layer; (3) the third layer is the Modal, a very soft, cool, and breathable fabric.

Yes!!! You can wear UltiUndies 24/7 and feel comfortable, safe and protected.

Our fabrics are free of PFAS & PFOA chemicals which are harmful to people and the environment. Our middle fabric is organic cotton infused with silver ions which inhibit bacterial growth, control bad odors, and create long lasting freshness without toxic chemicals. Our top layer which touches your skin contains anti-microbial and anti-fungal properties.

We at UltiUndies used two methods of testing. The first and most reliable test was wearing the undies and purposefully peeing before reaching the toilet. It was hard to measure the exact amount of pee that came out so we also tested the undies absorbency tolerance by dripping teaspoons of water on the crotch of the undies. On both instances we made sure that the outer layer of the crotch was dry and did not wet or stain the outer clothing. It was a fun and crazy experiment! Our conclusions were as expected, leakproof protection 24/7!!!

Modal is a fabric derived from sustainable-produced wood. A sustainable-produced wood comes from a forest where the owners keep their forests healthy, protect clean water and wildlife habitat, and continually replant and more. The ecosystems in these forests are kept healthy.

UltiUndies are made with the finest fabrics and trimmings. For ULTIMATE care we recommend washing your undies by hand. We are realistic, however, and feel this might be an extra inconvenience for you. Your undies can also be machine washed on a delicate cycle in cold water with light colors and tumble dried on low heat. Please … do not use bleach or fabric softeners and do not iron.

UltiUndies fit true to size. Please check our size chart under “My Size” and you’ll be able to determine your correct size.
