PRE-COLLECTION — SHIPPING FROM LATE OCTOBER 2026

Triple Stripe is available for pre-order as part of an initial limited production run of just 120 pieces.

Orders containing this item will ship from late October 2026. (Any order including this product will be shipped in its entirety from late October.)

It could become the next permanent addition to the Boxer↑Up collection. For now, we've produced just 120 pieces.

Triple Stripe introduces a new blue-striped fabric on a white background, inspired by classic Italian tailored shirts.

What makes the design distinctive is its pattern: each stripe consists of three fine blue lines, creating a more refined and distinctive look than traditional stripes.

This first production run is part of the Boxer↑Up Pre-Collection: a selection of new fabrics introduced in limited quantities before their potential inclusion in our permanent range. Our customers' preferences will help determine which designs become permanent additions to the collection.

On the outside, it retains the elegance of classic boxer shorts.

On the inside, it hides what makes Boxer↑Up different.

Our exclusive internal support, made from 100% breathable cotton, gently supports your intimate areas and keeps everything comfortably in place, without compression or altering the boxers' appearance.

Crafted from our premium stretch shirting fabric — 72% cotton, 25% polyamide and 3% elastane — it combines breathability, softness and freedom of movement with a fit that stays perfectly in shape throughout the day.

Every detail is designed to deliver exceptional comfort:

  • Internal support made from 100% cotton

  • Premium stretch shirting fabric

  • Ergonomic construction with a contoured back

  • Button-front opening

  • Flat seams

  • No internal labels

  • Carefully calibrated stretch that never feels restrictive

  • Made in Italy

First production run: 120 pieces.

Shipping from late October 2026.

Triple Stripe joins our Pre-Collection today.

It could become one of the next permanent additions to the Boxer↑Up collection.

The qualities

Boxer↑Up are designed to offer an infinite level of comfort thanks to their exceptional breathable properties. Made with an innovative internal semi-slip or Hold-up and a stretch cotton fabric, our boxers guarantee optimal ventilation, keeping the skin fresh and dry throughout the day.

Main Features:


  1. Breathable Fabric : Our stretch cotton is designed to promote maximum breathability. The special composition of the fabric allows for rapid evaporation of sweat, reducing the sensation of humidity and preventing skin irritation.
  1. Lightweight Microfiber : Embedded with elastic microfibers, the fabric is incredibly lightweight and soft to the touch, offering a silky-light feel. This not only improves comfort but also allows for greater freedom of movement without restriction.
  1. Advanced Ventilation Technology : The structure of the fabric, thanks to its high-quality features, has micro-holes that facilitate the passage of air, ensuring continuous ventilation. This is particularly useful during hot days or intense physical activities, maintaining an optimal body temperature.

  1. Moisture Wicking : Thanks to the hydrophobic properties of stretch cotton, our boxers quickly absorb moisture, keeping you dry and comfortable. Thanks to the 100% cotton inner half-slip. This is essential to avoid chafing and irritation, especially in humid environments or during sports activities.
  1. Ergonomic Design : The Milano Boxer Briefs are designed to perfectly adapt to the shape of the body, ensuring optimal support without compressing. The flat seams and the absence of internal labels add an additional level of infinite comfort, preventing any form of irritation.

Benefits of Breathability:

  • Long-lasting Comfort : Wearing our boxers means enjoying a feeling of freshness all day long, regardless of the external conditions.

  • Prevention of Irritation : Effective moisture management helps prevent redness and especially skin irritation, ensuring healthy skin.
  • Improved Performance : Whether you're working out, playing sports or just relaxing, the breathability of our boxers keeps you focused and comfortable in every situation.

Sustainability

For us, sustainability also and above all means feeling good about yourself and having no regrets, because external beauty must mirror internal beauty. We want those who wear Kloters to be aware of the fact that their well-being has not been achieved at the expense of the well-being of others.

This is why all our garments are designed and produced to last a long time, not for the quality as an end in itself, but because we are aware of the impact generated by producing, distributing and disposing of clothing on the environment: if the products last more, less is produced and the environment benefits.

In fact we are constantly looking for materials that reduce the impact that their production or use have on the environment. All our suppliers are Italian, in order to have a direct and personal relationship with them and to be able to select them from those who share our ideals and who do not exploit their collaborators to obtain profit. And, being close to us, we minimize the impact that the transport of goods and merchandise has before reaching the final customer.

We also work tirelessly to offer our products at the right price, to ensure that we can feel good for as many people as possible, without however this happening to the detriment of our collaborators or suppliers.

Kloters , by its nature, respects the environment and believes that apart from a few product categories, there is no urgency to receive a purchase within 24/h, negatively impacting the environment and people's safety.

(If you have emergencies or special occasions, you can indicate a priority date in the notes and your order will be shipped according to your instructions).

No Packaging

At Kloters, we are committed to sustainability. Here's how we reduce our environmental impact:

  1. Minimum Packaging : Our Milano Boxers are shipped in a simple nylon bag (which you can recycle into plastic) for hygiene reasons, avoiding elaborate packaging that would immediately end up in the waste.
  2. Waste Reduction : We save tons of unnecessary materials, contributing to a lower ecological impact.
  3. Best Quality and Free Shipping : We invest the savings in the quality of our boxers and offer free shipping with the purchase of three or more pairs.

Men's boxer shorts with internal support in cotton shirt

Not all boxers are the same.

Boxer↑Up was born from a simple idea: to maintain the elegance of the classic cotton boxer shorts, eliminating their limitations.

The fabric is the same as quality shirts: fine cotton, soft, cool on the skin.

The difference is inside.

The discreet internal support (push-up) offers natural stability throughout the day, without compressing or constricting.

It is not a hidden brief, but a support designed to accompany movement and to obtain comfortable men's underwear.

The result is a quality men's boxer that remains composed, clean in line, pleasant to wear from morning to night.

Why choose a boxer with internal support

Many men choose loose-fitting boxers for aesthetics and freshness, but sacrifice support.

Others choose briefs or tight-fitting models, sacrificing freedom and style.

Boxer↑Up combines both:

• elegance of the traditional boxer

• internal anatomical support

• high quality breathable cotton

• flat seams that do not irritate

• natural fit on every body type

It's intimate that you don't notice, but you feel.
