What the Heavy Flow 6 Pack actually gives you
The Heavy Flow 6 Pack is a six-pair set built around one absorbency level: Super. You get three Classic Boyshort Super Black and three Classic Bikini Super Black, both rated at 50 mls, which the catalog describes as up to 10 tampons (based on a 5ml tampon). That makes this pack a straightforward way to stock up for the heaviest days and overnight rather than a mixed-absorbency sampler.
The value case is simple: six pairs at the pack price of USD 224.36, compared with a catalog comparison price of USD 329.94. If you already know you want Super absorbency for most of your cycle, the pack removes the guesswork of buying singles. If you need lighter absorbency for the start or end of your period, this pack alone may not cover every day.
Pack contents and absorbency at a glance
- Heavy Flow 6 Pack: Pack includes Classic Boyshort Super Black x 3 and Classic Bikini Super Black x 3. You get two cuts in equal numbers, so you can test both fits before committing to more of one style.

Heavy Flow 6 Pack - Heavy Flow 6 Pack: Flow: Super. Absorbency: 50 mls. Tampons equivalent: up to 10 tampons (based on 5ml tampon). This is the highest absorbency in the pack, intended for heavy days and overnight.

Classic Boyshort vs Classic Bikini: which cut for which day
Both styles use the same Super absorbency and black color, so the real decision is coverage and fit. The boyshort sits low on the legs, just above the hips, and the catalog notes it is ideal for side sleepers or under skirts and dresses. The bikini sits on the hip with a high-cut leg for a smooth, comfortable fit and is described as one of the most-loved styles and a good starting point if you are new to Modibodi.
- Classic Boyshort Super Black: Extra coverage and a low leg line. A practical choice for overnight, side sleeping, or wearing under dresses and skirts when you want more fabric around the leg.
- Classic Bikini Super Black: A high-cut leg and hip-level rise. A familiar everyday shape that works well under jeans and fitted bottoms, and a sensible first pair if you are testing period underwear.
A realistic rotation for a heavy flow
Six pairs is enough to get through a heavy period without daily laundry, provided you pair the pack with a wash routine. The catalog care instruction is consistent: rinse first, gentle cold machine wash, hang to dry, reuse, and repeat. Plan around that air-drying step, because it is the part that dictates how quickly a pair returns to the drawer.
- Day 1–2 (heaviest days): Wear a boyshort or bikini during the day and change as needed. Keep one clean pair set aside for overnight.
- Overnight: The boyshort is the natural pick if you sleep on your side or want extra coverage. The bikini works too if you prefer a higher leg.
- Day 3–4: Continue with Super absorbency if flow is still heavy, or switch to a lighter style if you already own one. The pack stays useful as backup.
- Wash day: Rinse used pairs first, then gentle cold machine wash and hang to dry. With six pairs, you can wash a batch while others are in use.
- Rebuild the drawer: Fold dry pairs back into rotation. Six pairs gives you a buffer for overnight drying and unexpected changes.
Sizing: the pack lets you mix sizes across the two cuts
The variant list shows that the bikini and boyshort sizes can be chosen independently. For example, one option pairs a US 4/XS bikini with a US 6/S boyshort, and another pairs a US 6/S bikini with a US 4/XS boyshort. That is useful if you prefer a snugger fit in one style and a roomier fit in the other, or if you are between sizes. Check the size labels on each product option before you order, because the pack does not force a single size across both styles.
Is the multipack worth it for you?
- Choose the 6 Pack if: You want Super absorbency for heavy days and overnight, you like having both a boyshort and a bikini in rotation, and you prefer to buy six pairs at once rather than build up singles.
- Look at a mixed-absorbency pack instead if: Your period includes several light days and you want lighter styles for those days. This pack is all Super, so it is not a full-cycle sampler.
- Buy fewer pairs first if: You have not tried either cut. The pack is a commitment to six pairs; if you are unsure about fit, start with one style and build from there.
Care rules that keep the pack in rotation
The supplied care instruction applies to both styles: rinse first, gentle cold machine wash, hang to dry, reuse, and repeat. Following that sequence protects the absorbent lining and keeps the fit consistent. The catalog does not list additional care steps such as bleach, fabric softener, or tumble drying, so stick to the stated method and treat any other guidance as unconfirmed by the supplied information.
