1. Swimming during periods 

Fact: You only need protection to manage the gush of flow once out of water.

Your flow is halted or insignificant when you are immersed in water, solely a phenomenon of buoyancy. The flow will return or gush out once you are out of the water, that's when you need Vitals for the actual protection.

2. Why Vitals period undies while swimming?

Fact: Breathability and No bulk.

Vitals Originals are breathable and swim-friendly. There are no bulky fabrics like in the absorbent gusset. Vitals won't get 'filled up' or 'soggy' when immersed in water. Wear a fresh pair every time you get into the water.

3. Where can you swim in Vitals?

Fact: Natural Pools - Low Chlorinated Pools

Because all styles in Vitals have 95% natural fibers, it's best to wear them in natural water bodies. Wearing them in heavily chlorinated pools could shed out the fibers. Vitals are perfect for non-performance based swimming.

4. Can the flow escape into water?

Fact: No. There is little or no flow when in water.

Wear a fresh pair when entering into the pool. Buoyancy will help here and the flow will only continue once you are out of water. There is no way you will flood the pool red or pollute the water for others.

5. Can disease spread through water?

Fact: Nope. Not a chance.

Blood cannot sustain in water. Blood-borne diseases can only transmit through blood, sex or pregnancy. Scientifically blood compounds burst, shrivel or get inactive in water. Hence, disease cannot spread.

Materials & Durability

Materials: Bamboo Jersey(body) ; Cotton Jersey (gussets) ; VitalX™ (all natural blend core for heavy flow underwear); Eco-PU* (Trims). *Synthetic neutral by funding recycling and cleanup projects.

We do not use synthetic cores like polar and microfleece. More than 95% of our materials are natural fibres for extra breathability and comfort. Vitals lasts you a minimum of two years and more with proper care.

How do they work?

Leakproof underwear also go by the names period underwear, incontinence underwear. Vitals is an unconventional product the modern times offer. We paired comfort and style with ground-breaking absorbent yet breathable tech to keep your southern regions fresh and dry around the clock. Cherry on top? They are washable and reusable for more than two years with proper care. 

Here's how they work:  Vitals comes with a built in gusset that absorb, wick and retain your flow. Think of a layered sandwich panel of natural, breathable fabrics bound together with a leak-resistant backing. The absorbency coverage varies from styles, but all our styles are leakproof all the way till the waistband and till the public bone or all the way in the front.
