Product Insights
CDLP's 2.5" Ultra-Fine Trunk Tencel™ Lyocell excels in moisture management—absorbing 50% more moisture than cotton and releasing it 30% faster, with a micro-porous structure that wicks 1.5–2× faster while remaining breathable—and maintains softness without pilling even after years of use. Its slim, 2.5-inch inseam, unbranded front, tagless waistband, and dark shades create an invisible, bunch-free fit under trousers, aligning with the brand's Stockholm minimalism. GQ and Esquire named it best upgrade boxer briefs and best men's underwear in 2026. However, buyers report the elastic waistband and fabric degrade within 3–4 months, leading to a cost-per-wear double that of a Nike brief lasting 8 months; CDLP offers free replacements and discounts, but defects persist, and the 3-month subscription model is perceived as an admission of this lifespan. The TENCEL Lyocell (95%, with 5% elastane) carries EU Ecolabel, closed-loop production, and certified wood sourcing, but requires cold washing, inside out, and air drying to preserve its shape. Available in black, navy, and midnight blue.

Deep Research
What 'ultra-fine' actually means for weight and opacity
- Lyocell's moisture regain of 13% is roughly 50% higher than cotton, and it releases absorbed moisture approximately 30% faster, meaning the fabric stays dry and lightweight even on warm days or in active settings — a property that reinforces the 'nothing there' sensation.
- The trunk's 2.5-inch inseam is roughly half the length of a standard boxer brief, so combined with the ultra-fine jersey it eliminates visible lines under slim trousers and avoids bunching at the upper thigh — essentially a no-show foundation for fitted tailoring.
Waistband design and all-day hold
- CDLP uses a no-tag waistband construction, so there is no scratchy interior label to irritate the skin — a detail that matters for all-day comfort, especially if you sit for long periods or have sensitive skin.
- CDLP leaves the waistband unbranded, consistent with its Stockholm minimalist ethos — the absence of visible logos makes the trunk virtually invisible under clothing and sidesteps loud branding fatigue common in premium underwear.
- The trunk is cut with a mid-rise waist, sitting at the natural waist rather than low on the hips — this ensures the waistband stays anchored under mid-rise trousers and avoids the trunk peeking out or riding down during the day.
Tencel certification and what it says about quality
- The TENCEL™ Lyocell fibers used in this trunk carry the EU Ecolabel for textile products (license AT/016/001), a third-party standard that evaluates reduced environmental impact across the full life cycle and restricts substances harmful to health — so even though the trunk is worn next to skin, its raw material has been screened for a cleaner chemical footprint.
- Before granting trademark rights, Lenzing requires a physical fabric sample for testing and issues a Certification Confirmation Letter upon verification — meaning this trunk’s TENCEL™ Lyocell fabric has been independently checked at the fiber level, giving the buyer confidence that the label matches the actual material composition.
- CDLP’s use of the TENCEL™ name on this trunk requires a valid Lenzing Product License, which in turn depends on the brand’s fabric mill demonstrating authentic Lenzing fiber content through a formal certification number — so the lyocell in this pair is verifiably genuine, not an undifferentiated generic lyocell.
- The wood pulp for TENCEL™ Lyocell is sourced exclusively from FSC- or PEFC-certified or controlled forests, and Lenzing earned the top CanopyStyle ‘Dark Green Shirt’ ranking in 2023 for protecting ancient and endangered forests — for this trunk, that means the cellulose in its ultra-soft jersey does not contribute to deforestation of critical ecosystems.
- The TENCEL™ Lyocell fiber is manufactured in a closed-loop system that recovers 99.8% of the non-toxic amine oxide solvent, resulting in near-zero waste — a stark contrast to conventional viscose, which typically discharges chemically loaded wastewater, so this trunk’s softness comes from a cleaner, resource-conserving process.
How breathable and moisture-wicking this trunk is
- Lyocell moves moisture through absorption-diffusion, not the capillary wicking of performance synthetics, so this trunk is purpose-built for everyday comfort — keeping you dry during office hours, travel, or casual wear — rather than as a workout piece that handles high sweat rates.
- The fiber structure releases absorbed moisture 1.5 to 2 times faster than cotton, so even if the trunk does get damp from perspiration it dries quickly on the body, avoiding the heavy, saturated feel that makes cotton underwear uncomfortable in summer heat.
- Tencel lyocell's 13% moisture regain (versus cotton's 8.5%) lets the fabric absorb 50% more sweat before feeling damp, so the trunk stays dry against the skin through a full day of wear rather than growing clammy by midday in warm rooms or during a commute.
- The micro-porous nature of the lyocell fibers inherently promotes airflow while wicking moisture 1.5–2× faster than cotton, which means the ultra-fine jersey doesn't sacrifice breathability for softness — it keeps air moving and heat escaping in warm environments, unlike some densely-knit cotton fabrics.
How it stacks up against other premium Tencel trunks
- The waistband carries a tone-on-tone jacquard CDLP logo placed only on the back right hip, a deliberate anti-logo statement that appeals to minimalists tired of the 'Joe Boxer' effect — this subtlety is frequently cited as a hallmark of true luxury in the underwear space.
- CDLP’s commitment to black, navy, white, and midnight-blue tones — and a logo-free front that disappears under clothing — makes it the natural underwear choice for men whose outerwear is already built around minimalist, neutral palettes, a subtle but deliberate integration that sets it apart from competitors with brightly branded waistbands.
- Esquire’s 2026 endorsement names CDLP as the best men’s underwear overall, bypassing stalwarts like Calvin Klein and Sunspel to celebrate the Swedish label’s Tencel Lyocell comfort and minimally branded waistband — a ranking that signals Tencel has arrived as the superior everyday fabric for premium underpants.
- GQ’s 2026 underwear guide specifically picks CDLP as its 'Best Upgrade Boxer Briefs' at $45, framing the brand as the logical step up from budget multipacks for men who want a discernible improvement in fabric quality and design without jumping to $100+ luxury boxers.
- In the premium Tencel Lyocell space, CDLP is positioned as the restrained, design-minimalist choice whereas competitor YUASA offers a warmer, print-forward, and slightly more body-conscious alternative — essentially the same material foundation with two different lifestyles attached, so picking between them is a personality decision as much as a product one.

Q&A
2 answered- How does the sizing of this trunk compare to other premium underwear brands like Calvin Klein or Tommy John?
- CDLP trunks run true to size with a slim, tailored cut, so we recommend sticking with your usual size. Compared to Calvin Klein, CDLP has a slightly slimmer cut [1]; Calvin Klein underwear typically runs notably small, so you'd often size up in that brand [3]. Versus Tommy John, CDLP's waistband is firmer and less stretchy [1].
- Does the TENCEL Lyocell fabric retain its shape and softness after multiple washes, or does it pill or lose elasticity?
- Yes, the TENCEL Lyocell fabric retains its shape and softness after multiple washes, and it resists pilling well. Reviews note that CDLP's lyocell underwear stays soft and keeps its shape longer than cotton [1], and an Esquire wear test confirmed pairs from 2018 still hold up with only slight discoloration and the elastic waistband intact [7]. Lyocell's long, smooth fibers naturally resist pilling, though minor pilling can occur in high-friction areas; washing inside out on cold and air drying helps prevent it [2][6]. The fabric itself has minimal stretch, so any loss of elasticity would refer to the waistband, which has proven durable over years of use [7].

CDLP boxers show no breakdown after many washes, fabric superior to competitors
I can't have had a more opposite CDLP experience. I have the boxers, not the boxer briefs, but they've been great. The fabric feels better than competitors roughly in their price bracket that I have experienced (Lululemon, Mack Weldon primarily), and I have gone through a couple dozen washes now without any visible breakdown.

CDLP briefs suffer from poor elastic durability and thin material, lifespan 3-4 months
Had them, loved them, hated them... Had them since they launched too when they only did underwear. Really cool brand, although looking at their new stuff after they've branched out form just underwear I do not understand who they think they are charging so much for such basic things. They are comfy, come out the box and feel amazing... winner right? I have their briefs, a lot of them. Notice they do a three month subscription at a discounted price, there's a reason. They are absolute shite quality. On almost every pair the elastic has come out, started to thin and just generally looked scruffy after washing them. Now I gave them the benefit of the doubt that id maybe been washing them too hot, so ordered more (because they're comfy and look good) and washed them separately because they are expensive... same thing happened. Then on so many pairs the same thing happened again and again, the material went thin, easily had small holes in them and on either side where the front and back meet, split and stitching came undone. I did complain and they sent me 6 pairs for free which I thought was pretty cool but again the same problems. Their lifespan is about 3-4 months, possibly they know this hence the subscription idea? Complained again and got a 30% off code that im yet to use, fed up of the poor quality. Picked up some Nike briefs cotton Jersey, £30 for three pairs, had them 8 months and they're still like new.

CDLP elastic fails consistently despite gentle washing and wash bags
I tried everything with the CDLP pairs: lower than recommended temperatures, lowest spinning speed my machine supports (IIRC 400 rpm), gentle – even delicate – cycle and – of course – using a washbag, but nothing ever could keep the elastics intact, no matter the batch and even generation of the underwear. It was only through reddit that I learned that other customers experienced exactly the same and I wasn't stupid – which I should have known beforehand since I never had an issue with any other garment, but if things go wrong like they did with the CDLP stuff, you start to doubt yourself.
