The Sleep Tight
Designed with heavy periods in mind, The Sleep Tight provides exceptional absorbency for a comfortable leak-free sleep without sacrificing style.
With heavy absorbency going all the way up both back and front, The Sleep Tight also provides extra protection for a long day at the office, or is perfect for postpartum.
Flow: Heavy = 20ml / 4 regular tampons.
Heavy: if you have heavier flow, this is your go to!
*Disclaimer: The Sleep Tight run a little smaller than our other sizes, if you are in between sizes we would recommend choosing the larger option. Should you have any questions, please email us on hello@wunderthings.com.au and our team will be happy to assist further.
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.
