Everyone loves our Altitude Briefs, because they’re amazing, but we had customers asking for some less brief briefs, and who are we to argue? So here they are! Same amazing fabric, feel and performance as our all time best selling briefs. But with more coverage.

The perfect foundation for literally any activity in any conditions, cool or warm. The natural breathability will keep you comfortable all day long, and beyond. Soft, lightweight, and perfect for everyday use as well as on multi day treks, on mountain or doing whatever it is you do out there when you’ll be extra grateful for the temperature regulating performance.

Tag free labels, flat lock stitching and an ultra soft waist band help eliminate chafe and maximise comfort.

Really pleased

Really pleased with these. Very comfortable to wear. Great quality. True to size.

So comfy

The most comfortable merino underpants I've tried so far, I want to wear them all the time. The fabric is super soft and I love that they don't cut through my butt cheeks, so they're minimally visible through clothing.
I wish I tried these sooner, before wasting money on other brands.
I'm only slightly concerned about their durability, as I heard the sound of ripping stitches a few times when pulling them up or down, but maybe I should handle them more delicately: I'm new to the merino world and I'm still learning how to care for the garments.

Hiya, thank you for your words Federica! We're so glad to hear that you find our Altitude Full Briefs to be comfortable and soft. We understand your concern about the durability and we recommend handling them delicately as our merino garments do require special care. We do have a care guide available on our website that can help with the care instructions: https://iomerino.com/pages/iomerino-care-guide
We do also offer a one year warranty on products purchased solely from our online store. If a manufacturing fault occurs under normal use (not including general wear and tear) please feel free to email us.
Thanks for choosing iO and welcome to the merino world! :)

My favorites!

Will keep buying these briefs. Great fit! Good for hot or cold weather. I am a many time return customer

A 2nd order because my first order proved really great, comfy and true to size. Will be irdering more as time goes on now as well.

Thank you so much for your continued support and for taking the time to leave such a lovely review! We're thrilled to hear that you're loving your second order and that our products continue to deliver on comfort and fit. Knowing they’re true to size and feel great makes our day! 💛

Super comfy

Im so happy with these briefs!
I wanted some merino underwear for a long thru hike so I wanted them to be really comfortable with good coverage around my curvy bum and tummy, with no digging in around waistband or legs, and no riding up or down, and no scratchy seams. I'm 165cm tall, 70kg with a curvy tum, and usually a size 12. I ordered the XL size and they actually fit all the above requirements perfectly! I was concerned they would be too big and saggy but the size is actually perfect.
Quick delivery and a good deal on buying 3 pairs together.
Happy customer! 😊

Awesome knickers - very comfy indeed and very happy with this oroduct that is such a difficult item to replace when your favourites are discontinued- my new go-to's.

Amazing knickers!

I will be buying more. They are sooo comfortable and they breathe!

Altitude Full Brief

Lovely texture and well made, but unfortunately for me these are to short in back, I’m an older person and need my lower back covered. Have returned two pairs, very well made, but will swap for a top. Sorry guys.

Super comfortable. Great fit. They do not move. Don’t know you are wearing them. I will be buying more.

Altitude Full Brief

Very light & comfy for a curvy body. Soft & not itchy. Don’t ride up when walking.

Comfy & Great

The full briefs are beautifully made & very comfy. More of a "midi" brief than a full but I found them to be the most comfortable merino briefs I've worn. Well done io! For women looking for guidance on sizing, I'm an hourglass figure, usually a size 14-16 in pants. I opted for an XL as that's the size I buy for Altitude tops. The XL fits nicely but I am considering sizing up next purchase, for extra comfort. In the short time I've owned my full briefs, they've become my favourite. Really happy. Fabric quality is excellent.
