I have been wearing Flexifit briefs for some time now - these are soft and comfortable and no VPL! The design has changed slightly but they are still good value and wash and wear well.

Odd sometimes

Originally posted on marksandspencer.com (UK)

Very cool and comfortable in the summer, but with a pair of cargo trousers (no others!) they completely roll down - they must rub on a seam/belt. Can be odd and embarrassing. So be warned. Otherwise good - I have got 9 pairs.

I have bought many of these over the years, they are comfortable & easy to wash on 30 degrees. I hope M&S keep selling these as every time there is a 20% off I keep buying them, just in case they do!

Briefs? I forgot I was wearing them!

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I prefer full briefs mostly because they cover and protect old battle scars from multiple abdominal surgeries, whereas smaller briefs always manage to align themselves directly and irritate those scars. These are buttery soft, lightweight and so comfy that you can forget you’re wearing them. The only reason I marked them down to 4 stars was because I didn’t read the description properly and assumed they were control briefs. They are very stretchy and move with your body but they won’t flatten your tummy! They are so comfortable though. I will be buying more!

Flexifit knickers

Originally posted on marksandspencer.com (UK)

I bought the skin tone colour knickers. They are very soft and comfortable to wear. They don’t dig in like some. I have given 4 stars as they are very expensive for what they are, otherwise I’m pleased.

Very comfortable and long lasting

Originally posted on marksandspencer.com (UK)

Comfortable and long lasting. I have bought lots over the years and they are great. They wash and dry perfectly and are comfortable to wear every day. Minimal VPL so perfect everyday knickers. I'm sure I'll keep buying more as long as they keep selling them.

I buy these Knick all the time. I pack about just over 2 weeks ago and each pair the sticking has come out. I presume it's a bad batch as this has never happened with the others I already have

I love these but.... the 14 I bought last time is a better, bigger size than the 14 I bought recently which are too small?? Very annoying lack of consistency!
