Silver Ion Tees + Modal Boxer Briefs

Legacy Co Official essentials are built around one principle: your basics should work harder than you do.
That means premium fibres, performance engineering, and comfort that holds up in real life—heat, sweat, long days, travel, and repeat wears.

This page explains what our fabrics are, how they feel, and why they perform.


Quick summary 

  • Modal = premium cellulose fibre known for silky softness, breathability, and a clean drape.

  • 200 GSM Modal (Briefs) = heavier-weight modal for structure, durability, and a more “luxury” feel.

  • Silver ion infusion = helps reduce odour build-up by inhibiting odour-causing bacteria on the fabric.

  • Anti-chafe panel (Briefs) = engineered inner-thigh comfort to reduce friction and ride-up.

  • Moisture management = modal is hydrophilic, meaning it attracts/absorbs moisture, helping fabric feel less clammy.


The Fabric: Modal

What is modal?

Modal is a premium cellulose-based fibre made from plant material. It’s known for a smooth, soft finish, strong everyday comfort, and breathability.

How modal feels

Think: luxury-soft, clean against the skin, and light enough to wear all day—without that stiff “new tee” feel or scratchy cotton dryness.

Why modal performs

Modal fibers are hydrophilic (they attract/absorb moisture). In practice, that can help with:

  • less sticky, less clammy wear

  • better comfort when you sweat

  • a smoother feel against skin

Modal vs cotton vs bamboo (plain English)

  • Cotton: classic, but can feel heavy or clingy when wet depending on knit/weight.

  • Bamboo viscose: can be soft, but quality varies wildly; some blends pill quickly.

  • Modal: consistently silky-soft, breathable, and often more “premium” in hand feel and drape.


Smart Tech: Silver Ion Infusion

What does “silver ion infused” do?

Silver ions in textiles are used to help inhibit odour-causing bacteria on the fabric. That supports odour resistance, meaning your tee or briefs stay fresher for longer—especially on sweaty days.

What you should expect

  •  Reduced odour build-up across the day

  • A fresher feel between washes

  • More confidence in close-range moments (gym, office, travel, dates)

What it’s not

It’s not a medical product and it’s not a promise that odour will never happen. It’s performance support, not a miracle—just a smarter baseline.


Product Tech Breakdown

Silver Ion Infused Tee

Built for: sweaty days, layering, everyday comfort

This tee is designed for people who don’t want to think about their shirt after they put it on. It’s soft, breathable, and made to feel clean and wearable from morning to night.

Key benefits

  • Ultra-soft modal feel: smooth, premium comfort against skin

  • Odour resistance support: silver ion infusion helps reduce smell build-up

  • Breathable wear: designed to stay comfortable across temperature swings

  • Everyday drape: looks sharp casual or dressed up

  • Embroidered logo option: front embroidery only (clean and minimal)

How it should feel
Light, smooth, and “fresh” longer—especially if you run hot.


Ultra-Soft Modal Boxer Briefs

Built for: all-day wear, anti-chafe comfort, support that stays put

These aren’t “just comfy underwear.” They’re engineered—fabric weight, stitch strategy, panel design, and pouch support all doing a job.

200 GSM heavyweight modal (why it matters)

200 GSM means a more substantial fabric weight. In underwear, that translates to:

  • a more premium, structured feel

  • better resistance to the thin, flimsy “stretch-out”

  • durability you notice over months, not days

Anti-chafe panel engineering

The inner-thigh panel is designed to reduce friction and irritation, helping with:

  • less chafe on long days

  • fewer distractions during movement

  • reduced ride-up for a more stable fit

Pouch support (real-world detail)

Modal is naturally stretchy, which feels great—but support matters. That’s why the pouch seams are built with additional elastic support, designed to hold you comfortably without crushing or shifting.

Odour resistance support

Silver ion infusion helps reduce odour build-up, especially useful for:

  • gym sessions

  • summer heat

  • long shifts

  • travel days

Durability (R&D positioning without risky guarantees)

These briefs were developed through extensive real-world wear testing to ensure they stay soft, supportive, and sharp after repeated washes. The goal: less pilling, less pulling, more “like-new” longevity compared to many soft-viscose options.


Breathability & moisture comfort (the part most brands fake)

Breathability isn’t just “thin fabric.” It’s heat release + moisture handling.

Modal’s hydrophilic behaviour helps manage moisture so fabric feels less swampy. Combined with a smart cut and airflow-friendly construction, you get comfort for:

  • office → gym → dinner

  • warm climates

  • high-sweat days


Care Guide (keep them feeling new)

To extend softness, shape, and longevity:

  • Wash cold to warm (avoid hot when possible)

  • Use a gentle cycle

  • Avoid harsh bleach/soaks

  • Line dry when you can (or low heat tumble)

If you want, I can tailor this section to your preferred care instructions exactly.


Fit notes

  • If you get sizing wrong: hassle-free swap.


FAQs

Is modal breathable?

Yes. Modal fibres are hydrophilic, meaning they attract/absorb moisture. That can help the fabric feel less clammy, support moisture management, and stay comfortable across long wears.

Does silver ion fabric stop smells completely?

It’s better to think of it as odour resistance support. Silver ion infusion helps inhibit odour-causing bacteria on the fabric, which can reduce smell build-up and keep items fresher for longer.

Is modal more eco-friendly than cotton or bamboo?

It depends on sourcing and manufacturing. Modal is plant-based, and many people choose it for its efficiency and softness, but “eco” claims vary by supplier. We focus on durability + long wear, because longer-lasting essentials reduce waste over time.

Do these briefs stop chafing?

They’re designed to reduce chafe using an engineered inner-thigh panel and stable fit. If you’re prone to chafing, this design is built specifically for you.

Is modal stretchy?

Yes—modal has natural stretch and comfort. That’s why pouch construction and seam support matter, so it stays supportive rather than just “soft and loose.”

Will they pill like bamboo underwear?

Pilling depends on fibre, knit, friction, and wash habits. Our goal with the heavier-weight modal and build choices is longer-lasting softness and a cleaner surface over time versus many ultra-soft viscose blends.

Heavyweight Cotton Oversize Tee

280 GSM | 100% Cotton | 3D Embossed Branding

Some tees are “soft” until you wear them twice. This one is built different.

Our Oversize Tee is cut from 100% heavyweight cotton (280gsm)—a premium weight that gives you that immediate structure, drape, and presence the second you put it on. It doesn’t cling, it doesn’t collapse, and it holds its shape like it was made for repeat wear.

Why 280gsm matters

GSM (grams per square meter) is fabric weight. In cotton tees, 280gsm is heavyweight, which means:

  • More structure: the tee sits clean on the body instead of hanging limp

  • Better drape: it looks intentional, not accidental

  • More durability: designed to handle real rotation, not one-season wear

  • Less “see-through” stress: thicker cotton = more confidence

The feel: unapologetically soft cotton

Heavyweight doesn’t have to mean rough. We sourced cotton that feels smooth, dense, and premium—the kind of softness you notice instantly and then miss when you wear anything else.

Oversized fit, done properly

This cut is oversized by design: relaxed through the body, elevated in silhouette, and effortless on every frame. Style it loose, layer it, or let the weight do the talking.

3D embossed branding (luxury finish)

Instead of loud prints, the tee is finished with 3D embossed logo detailing on the chest and left sleeve—built in like a signature, not slapped on like a sticker. Subtle. Designer-coded. Clean up close.

In short: thick, soft, premium, and built to be worn on repeat—because once you wear a proper heavyweight cotton tee, the rest start feeling disposable.
