Barely-There Feel. Reliable Protection.

Light-flow period underwear can still feel sleek, flattering and effortless to wear.

The EvaBody Light Flow High-Waisted Period Thong combines a supportive high-rise waistband with a minimal thong cut, giving you a smooth, secure fit without the fuller coverage of traditional period underwear. Its high-cut leg creates a flattering silhouette, while the soft, stretchy fabric sits discreetly beneath close-fitting clothing.

Designed for lighter period days and spotting, it provides subtle absorbency when you want added reassurance without extra bulk. It is an easy choice under dresses, activewear, workwear or fitted outfits when you want protection that feels almost invisible.

It can also be worn for daily discharge or as backup alongside another period product.

Flattering support. Minimal coverage. Confidence without compromise.

Love this high-waisted design

The high-waisted cut is comfortable and gives me confidence on lighter days.

A style I'll keep repurchasing

I can see myself repurchasing this style because it fits my lifestyle so well.

Simple, sleek and comfortable

The design is simple but really well thought out and comfortable.

Perfect for travel and handbag emergencies

I keep one of these in my travel bag because it's perfect for unexpected spotting.

Feels like regular underwear

They genuinely feel like regular underwear rather than period products.

I finally found my ideal light-flow pair

I've tried a few light-flow options and this is easily my favourite.

Comfortable and discreet

Very comfortable and discreet. I just prefer slightly more coverage personally.

The fit feels very secure

The high waist makes me feel secure even though it's a thong style.

So much more practical than I expected

This was my first EvaBody thong and I'm impressed by how practical and comfortable it is.

Sits beautifully under clothes

I wore these under a fitted jumpsuit and they sat beautifully all day.

Perfect for those in-between days

These are perfect for those in-between days when a regular liner feels unnecessary.

Really nice but I'd love more colours

The quality is lovely.

Comfort without the bulk

I love having protection without the feeling of bulky underwear.

I reach for these constantly

I find myself reaching for this pair every month because it's so comfortable.

A really useful addition to my collection

I didn't think I'd use this style so often, but it's become one of my favourites.

Lightweight and easy to wear

They're lightweight enough that I barely notice them throughout the day.

Good for backup protection

I mainly use these as backup protection and they've worked really well for me.

The most comfortable thong I've tried

The fabric is soft, stretchy and incredibly comfortable.

No visible lines at all

I honestly forget I'm wearing these because they sit so smoothly under clothing.

I love the light grey colour

The light grey colour is so pretty and practical. It feels different from the usual black options.

Great idea but I'd size up

Really comfortable and well made.

The high waist is surprisingly flattering

I didn't think a high-waisted thong would suit me but it's actually incredibly flattering.

A thong that actually feels secure

I usually don't feel secure in thong styles, but this one feels surprisingly supportive.

Exactly what I needed for spotting

This is exactly what I wanted for those final days of my cycle when I only need a little protection.

Really comfortable for light days

Very comfortable for spotting and lighter days.

Perfect for leggings and fitted dresses

I wear a lot of fitted dresses and these are perfect because there are absolutely no visible lines.
