The Full Brief



Full coverage. Ultra supportive. Our go-to for a heavier flow.

Flow: Medium = 15ml / 3 regular tampons or Heavy = 20ml / 4 regular tampons.

Medium: useful for your entire period if you tend to flow light, or suitable from day 3 onwards if you flow on the heavier side. 

Heavy: if you have heavier flow, this is your go to! 

Try risk free for 60 days*

As a first-time customer, you can try one pair of undies for 60 days risk-free. If you don’t like how they function, we will happily give you your money back (minus the cost of shipping).

Unfortunately, garments that have been worn can no longer be returned due to sanitary reasons. And you know, the market for second-hand underwear isn't all that flash!

So, we will require a brief explanation of the reason for your request.  The trial applies to one worn garment only.

No further refunds, credits or exchanges can be given on any additional worn or washed underpants.

Current waiting time for out of stock items: less than 2 weeks (14/11/23).

Shipment of your in-stock items may be delayed until your pre-order item is ready for shipping. To ensure faster delivery of your in-stock items, we recommend making two separate orders - one for your pre-order items and one for your in-stock items.


Formulated with organic cotton and nylon made from recovered ocean plastics, these underpants whisk moisture away from your body (and plastics away from the turtles!), keeping you dry and "good karma'd" all period long.

Not quite absorbent enough

Unfortunately, I have super heavy periods. On day two I had to change my underwear 4 times as I was leaking. I was hoping they’d hold slightly more. However, there feel and comfort to wear was much better than other brands.

Hi there! Thank you for taking the time to leave a review for 'The Full Brief'. We're sorry to hear that it didn't quite meet your expectations in terms of absorbency. We understand that everyone's flow is different - you may want to try our 'Sleep Tight' which is designed for heavier periods and offers more absorbency.

Fab brief

I go for a 10 in lacy bum and the 10 in the full brief fits nicely as well. Not as cute as the lacy bum but what is :) A great comfy knicker with slim gusset. I’m happy with this one!

Very Discreet

These undies are super comfortable and the absorbency is really thin, they feel like regular undies.
