Materials & Care

Origins is made using a soft blend of bamboo and modal, chosen because it feels good on the skin and stays comfortable throughout the day. It’s breathable, smooth, and designed for everyday wear — whether you’re sitting for hours, moving around, or winding down at night. Care: Machine wash cold. Tumble dry low. Avoid high heat to keep them feeling their best.

Size & Fit

Origins fits true to size. If you like a more relaxed feel, sizing up can work well. If you prefer a closer, more supportive fit, stick to your usual size. Use the size chart above if you’re unsure — it’ll guide you to the right fit.

Shipping & Returns

We offer worldwide shipping using efficient, lower-impact delivery methods. Orders typically arrive within 4–10 days, depending on location. If you’re not satisfied, you can return your order within 30 days for a full refund. Simple and straightforward.

Feel the Difference Instantly

Feel The Difference Instantly

Perfect for everyday wear.

I work long hours at a desk and always thought feeling hot and uncomfortable by mid-afternoon was just part of the day. The first time I wore Origins, that didn’t happen the effect was instant. I stayed comfortable right through until the evening. No heat, no shifting, no constant adjusting. That honestly surprised me.

I’ve tried a few ‘better’ underwear brands before, and they always felt fine at first but didn’t really hold up. Origins was different. I put them on in the morning and forgot about them — in a good way. By the end of the day, I wasn’t desperate to take them off like I usually am.

I’ve got sensitive skin, this is amazing!

I’ve got sensitive skin, so friction has always been an issue for me. With These, everything just felt calmer for me, I wasn’t as stressed as I always am. Nothing rubbed, nothing overheated. What stood out most was how consistent they felt all day. Once I noticed that, I didn’t want to go back.

Great quality product

Great quality product and lovely feel to the fabric. I received the wrong size (my own fault) but the company was brilliant to deal with and really helpful in sorting my mistake out.

Why These Will Change Your Life

Why These Will Change Your Life

We know it sounds crazy to say underwear can change your life. But it’s the first thing you put on every morning and the standard you start your day with. Men told us they didn’t realise how much they’d been putting up with until they stopped settling for it. Small things you do every day compound, and this is one of them. When you start the day wearing something that actually feels right, you carry that standard with you.

Questions? We've Got Answers

What makes BioFit Origins different from regular underwear?

Most underwear loses comfort as the day goes on.

Origins is designed to stay comfortable over long wear, reducing heat, shifting, and irritation.

Is BioFit Origins suitable for sensitive skin?

Yes. Many men choose Origins because it feels smoother and causes less irritation, especially during extended wear.

Will I notice the comfort right away?

Yes — most men do.

Around 90% of customers say they noticed the difference on the first wear, often within the first few hours. That’s the most common feedback we receive.

What if I don’t like the boxers?

Honestly? It’s unlikely.

But if Origins isn’t for you, that’s fine — you’re covered.

We offer a 30-day money-back guarantee, no questions asked.

And on top of that, every pair is backed by a 365-day quality guarantee.

Try them properly. If they’re not right, you won’t be stuck with them.

What does the 365-day guarantee cover?

If there’s ever an issue with quality or durability within a year, we’ll make it right.

Simple as that.
