Underdays Avis 

I absolutely love these, I’m totally converted. I started with 2 pairs now I have 10+. I love the fit details, they’re the most comfortable underwear I own. I have both the Everyday (in every color) and the Workout ones and I’m never going back. More colors please! I especially love the sets ❤️

Oh my god this underwear is a game changer! They are so comfy and absorb sweat and don’t smell after exercising! They are so comfy I forget I have them on. The quality is beautiful, the style is flattering. Setting the standards on what underwear should be, I won’t wear anything else. Worth every penny.

I received a stained top.

In the words of my lovely wife "they are so bloody comfortable"
Not only are they the most comfortable thongs she's ever worn, they also don't disappoint from the sexy aspect too
Will continue to purchase from Underdays

Love the underdays, have all their tank tops, their pijama (that they need to bring back!) and underwear, just the best brand ever!

Literally the best! Comfortable- Good material and styles! The bundle offer is great too!

Would love more colours green and blue! Missed out on the pale blue!

These are all I want to wear now. I prefer wearing thongs with most outfits, and these are the most comfortable ones I own. Feel barely there, wide enough gusset, breathable and soft fabric.

The best period underwear on the market. Absolutely love the material and the styles, super comfy!

Great quality, lovely material to wear, very quick delivery.
I will be buying more products from this company

These knickers are the best I have ever had!
Soft, sexy, comfortable, just perfect!
They don’t show through outfits.
No riding up whilst playing padel.
Love them.thanks so much,
Kate

Love these underwear it’s now all I buy! Comfortable cotton pants vibes but look a bit more elevated and like lingerie! My only complaint is, after a couple of washes (hand wash or machine, I’ve tried it all) I find the stitching loses colour and makes the whole thing look a bit less polished, particularly on lighter colours. Would love to see more no vpl options as the stitching on the edges can cause quite a pronounced line. Also, bring back blue!

So comfortable and flattering - will be buying more!

I’ve honestly struggled for ages to find underwear that feels comfortable, doesn’t irritate me, and actually sits right, so discovering Underdays has been such a game changer for me. What I find great about this underwear is the attention to detail — from the larger gusset to the extra seam, which allows me to move around without constantly needing to readjust. They’re so comfortable that I ended up throwing out all my old underwear and replacing it with Underdays — no regrets at all.

recently tried Underdays women’s underwear and I’m genuinely impressed. The quality is outstanding—the fabric feels incredibly soft, breathable, and comfortable enough for all-day wear. The fit is flattering without digging in or riding up, which is surprisingly hard to find. I especially love how supportive yet lightweight they feel, giving a smooth, seamless look under clothes. If you’re looking for comfortable, high-quality everyday underwear that still feels a little luxurious, I’d highly recommend Underdays. They’ve quickly become a staple in my drawer!

The product itself is amazing and I couldn’t be happier with the workout things themselves.

I have had numerous issues with multiple orders though. Missing items, one order not showing up at all, not able to fulfil order after order made. Each issue they have tried to rectify but not a great experience.

I have extremely sensitive skin that’s allergic to elasticized materials—so most underwear makes me break out in bumps. These are by far some of the most comfortable pairs I’ve ever had. Summer will be the real test, but so far, I’ve worn them without issue. And they look great, to boot!

I have been buying Underdays for years - now my underwear drawer is almost completely only Underdays. I love everything about them - the fit, the style and the colours. The workout range is also amazing - went to a sauna recently wearing them and my skin was absolutely dry underneath.

Bought several thongs for my wife, she loves the fit and materiel. Highly recommend. They look amazing.

I am so happy I found Underdays - I will never have to go another day with worrying about my underwear! Soft, breathable, supportive and comforable all day long.

Very good quality, wash well and are great for moisture wicking. Don’t buy any others now
