  1. i LOVE, LOVE, LOVE the FIRST VERSION of these panties, but the *Upgraded* version is not an upgrade.

    Posted by I thought I found the one (pair of undies that is)! on 4th Oct 2014

    I absolutely love these panties. So much so that I have bought MANY, MANY pairs. They do exactly what you expect: They feel weightless, seriously like they are barely there. The product itself, the *FIRST VERSION* , deserves 5 stars ......But....you can no longer get the first version so.....

    1) Before they changed the elastic around the openings, the panty lines truly were invisible, even with my thinner fabric dresses and pants. However, the new elastic bands that they have chosen have now made the panty lines very visible. they are thick and instead of laying flat on the skin, they pull in. I personally think that the issue everyone was having with them rolling or fitting loose (before the change) is because these underwear size a bit big. [ I can vouch for that because I ordered mine a pair too small (they were going to be a reward for meeting my goal weight) and they ended up fitting perfectly... and yes I made sure to order my regular size in the new version, just in case]. The new banding pretty much renders these underwear useless, as the ability to be near invisible is why I tried them and then the reason why I fell in love with them. I definitely WILL NOT order the new version of these panties. I would definitely be interested to see what other who have had both versions think.

    2) These underwear are definitely a good product, but they are offered at **LUXURY** prices. I've had my first pair, the original version for almost a year and they don't seem to have weakened and I still love them. I was okay with the luxury price tag at first because I wanted to support a new Canadian company and they gave the consumer a "luxury" experience by delivering the underwear in super pretty cylindrical tubes. But my last orders which I spent several hundred dollars on, showed up in little plastic see through bags no much different from a baggie you put a sandwich in or that a cheap 20cent toy comes in from the dollar store. SO, SO, SO disappointed with the way they are choosing to present their underwear to their customer: like they are nothing special. So why would we want to spend special amounts on them? Presentation is pretty important especially when you are ordering online at these high prices. Even if they were delivered in a little laundry bag or something else greener that could be reused, anything besides a baggie!

    I'm actually super sad to say that after falling in love and spending several hundreds over the past year, I probably won't be buying again. I thought I found the one (pair of undies that is!) :(

    P.S. Knix, if you have ANY of the first version laying around, I will purchase all of them haha! Seriously though, contact me!

  2. no more sweat

    Quite satisfied. Would buy more !!!

  3. very nice

    Posted by Linda on 1st Jul 2014

    I like these very much. I plan to order the boy short as well to try them out.

  4. Can't do without my Knix

    Posted by Unknown on 12th Jun 2014

    I started with one pair and simply had to order more. Knix is all I wear now. Bravo for a fabulous product.

  5. Love the concept!

    Posted by Kim on 2nd Jun 2014

    I truly love the concept of the product; however, the fit leaves something to be desired. They constantly fall down. I definitely ordered the right size. They need a band at the top or something.

  6. My new favourite panty

    Posted by Sara on 29th May 2014

    These underwear are so comfortable I want to wear them every day. They are light as air and you barely notice you are wearing them. The built in liner has saved me on more than one occasion during that time of the month. I'm a convert.

  7. Lousy panties

    Posted by Unknown on 28th May 2014

    These panties are light; so light that they don't stay up. They kept sliding down until they were wrapped around my upper thighs. Not good when you are wearing a dress or skirt. I will not purchase any more and hate that I wasted my money on the two pair I did buy.

  8. Not What I expected

    Posted by Unknown on 22nd May 2014

    Was not exactly what I expected. Got an excellent review in Women's First Magazine.

  9. Super Comfortable

    Posted by Holly on 27th Feb 2014

    Silky, comfortable, love that they are seamless. Will buy another pair for sure!

  10. Fits like a glove

    Posted by Angie on 23rd Feb 2014

    Love the fit especially under dress pants...no more panty lines
