Comfortable, Dry Quickly

I bought these for a future trip, but have tried them to make sure the fit was good. Sizings are accurate, the undies are comfortable. I'll likely buy a few more pairs before we leave!

Walked the Camino in them

Fantastic for hiking and everyday use. I bought two pairs of the bikini briefs for the Camino (40 days of walking) and they were fantastic. They dry really quickly. I would hand wash out a pair at night, roll them in a towel to get the excess moisture out, hang them up and by morning they were always dry. The bright pink colour made them easy to find in my pack too.

Comfy!

These are comfy, I'm happy. In terms of sizing I went with a size L as a size 12 normally and I think that works okay -- though if you're on the slimmer end of that size you might prefer a M for a more snug fit.

Excellent

I got the blue marle colour in XS. Love it! There was a problem with my order and IOMerino went over and beyond to rectify it, Really impressed.

Quick to dry

Brought a couple of these on a week long canoe trip to BWCA. They dry quickly which is what I needed when space and weight is limited in my pack.

Love it more than I thought I would.

I don't normally wear such low-cut underwear. I like things a bit higher towards my waist and i have a very long torso... there's a bit of belly that can hang over when i wear low stuff, as well as sometimes the top of the butt-crack showing, and then it's odd because it's outside the undwear, but inside the trousers... ANYWAY - these are super comfortable and unlike others i've tried in similar cut they have not ridden into places they don't belong! Incredibly soft and comfortable, but also sturdy and not so stretchy that they sag and scrunch into odd positions.They are a touch lower than i would pick, but they're STILL comfortable anyway!! I measure for a size XL, but the L is a better fit for me. I would absolutely buy more of these! (i wouldn't complain if a version came out that went up closer to my actual waist, though, too!)

Best knickers!

My new favouritest knickers - good coverage and they don't ride up.

Thanks Sarah!
