BIOFIT Essentials Boxer Trunks Green
What they're made of
92% bamboo, 8% spandex.
Bamboo is naturally softer than cotton:
no sharp fibres, no irritation, no uncomfortable rubbing.
It breathes in a way cotton simply can't, keeping you cool and dry whether you're at a desk, at the gym, or working outdoors.
They also hold up. Men are still wearing their first pairs twelve months later. Wash after wash, they keep their shape and their softness.
Wash at 30°C for best results.
Getting the right fit
Our sizes run smaller than standard sizing. We hear this a lot, so trust the size guide above before you order. Most men need to go up one or two sizes from what they'd usually pick.
Still unsure? Drop us a message. We'd rather take two minutes to help you get it right than have you order the wrong size.
Delivery & guarantee
Dispatched within 48 hours. Delivered in 7–10 days, worldwide.
Not satisfied? Return within 30 days for a full refund, no questions asked. We're confident you won't need it.
Effortless Comfort
No adjusting. No bunching. Just get on with your day.
Naturally Breathable
Bamboo breathes. Cotton doesn't. Cool and dry from morning to night.
These Last Long
Wash after wash. Still like new a year later.
For the man who's been putting up with less.
You shouldn't have to think about what you're wearing.
Most men have spent years adjusting, readjusting, dealing with it. The waistband rolling, the fabric riding up, the constant discomfort that you've just... accepted.
Biofit's bamboo fabric sits differently. Soft enough that you genuinely forget you're wearing them. No adjusting. No bunching. Just get on with your day, from the first hour to the last.
So comfy you almost forget you've got them on.
Cool and dry. All day. Whatever you're doing.
Cotton holds heat. Bamboo doesn't.
The difference becomes obvious by lunchtime on a warm day, or after half an hour at the gym, or on a long shift outdoors.
92% bamboo means the fabric breathes naturally, moisture moves away from the skin, temperature stays regulated, freshness lasts. No sticking. No discomfort building through the day.
I'm in Italy, it's 33 degrees and my nuts aren't sweaty.
One problem with boxers this good.
Men buying Biofit are still wearing their first pairs a year later, same softness, same fit, same shape after dozens of washes. No falling apart after a few months.
The 5+5 deal gives you 10 pairs in one go at £3.90 each. Enough to sort your drawer out properly and never think about it again.
Just make sure you order enough. Partners have a habit of claiming a pair or two for themselves. Which, fair warning, happens more than you'd think.
Much to my husband's absolute annoyance I've claimed a couple of pairs as my own... the comfort is unreal!
365 days. If it's not right, we'll fix it.
If your boxers develop a quality issue within the first year, a hole, a seam, anything that shouldn't happen, we'll replace them. No awkward back and forth. Just send us a photo and we'll sort it.
