Love

Yes, I recommend this

So comfy, TTS with room for bloat. I wouldn’t wear them without a liner on heavy flow days but great for lighter days and extra protection overnight

Good value

Yes, I recommend this

These are good value compared to other brands. They are extremely generous in size- which makes them comfy if you are bloated. They are quite bulky but good for price

Real piece of mind

Yes, I recommend this

These knickers have been a god send for my mum who has endometrial cancer bleeding. These knickers make sure her clothes and bedding are protected. I prefer the pink/burgundy colour but these are no longer available.

Leaked immediately - do not buy

No, I don't recommend this

Comfy and look nice

Really comfortable, soft and not bulky. Wash and dry well. Not as absorbent but happy to have more pairs and change more regularly.

Great product

Yes, I recommend this

I was sceptical on if these would work but now I couldn’t be without them. Wear them as a second form of protection when out and about but wear by themselves for sleeping. I sized up to account for period bloat and they are super comfy.

A bit disappointed.

These pants are a very good idea however they come up quite a bit larger than expected and are quite uncomfortable. I will keep them in the hope they will shrink a bit

They have changed them.

I bought the 'white mix' 3 pack (with white dots). They have changed the way they do the leg elastic - they have a thick edge and 2 rows of stitching, also the waistband elastic is different and irritating. Not sure why the change? I didn't realise, put them in my drawer and found out too late to return that they are different and not an improvement. This keeps happening, something you rely on and were happy to discover gets changed with no warning - sigh. Still wearable(needs must) but not happy with the changes.
