Tencel: Natural, Eco-Friendly, High-Performance Fiber

Tencel—also known as lyocell—is a fiber derived from wood pulp, produced through a closed-loop process that recycles over 99% of the solvent. At AYAQ, this fiber is not just an “eco” addition but a technical material that enhances stability, comfort, and moisture management in base layers. It is notably used in the SHIRWALI (men’s / women’s), a merino + Tencel shirt (~240 g) designed for cool to cold conditions where the body alternates between high intensity and slower phases.

1. A Natural Fiber with Genuine Technical Performance

Tencel offers properties particularly suited to endurance sports:

  • Rapid moisture absorption: the fiber captures water vapor before it condenses, stabilizing body temperature.
  • Soft touch with a slight cooling effect: beneficial during effort transitions.
  • Stable structure: the knit maintains its shape and resists pilling over time.
  • Naturally antibacterial: better odor control on long outings.

These features allow Tencel to enhance comfort without compromising technical performance.

2. The Merino + Tencel Synergy: A Core Choice at AYAQ

AYAQ does not use Tencel alone; it is blended with RWS-certified merino wool to boost the thermal and mechanical performance of the knit. In the SHIRWALI (men’s / women’s), each fiber serves a specific purpose:

  • RWS Merino: thermoregulation, insulation even when wet, odor management.
  • Tencel: comfort, rapid absorption, improved knit durability.

The result is a more versatile base layer capable of handling significant intensity shifts without becoming heavy with moisture. This is an asset for demanding hikes, ski touring, or cold alpine ascents.

3. A Fiber Fully Aligned with AYAQ’s Environmental Commitment

Tencel fits within a responsible approach:

  • wood sourced from sustainably managed forests,
  • manufacturing in an almost closed-loop process,
  • low water consumption,
  • European production consistent with AYAQ’s supply chain.

This transparency and impact control make it compatible with a durable, high-performance, minimalist wardrobe.

4. Why Include Tencel in a Modern Outdoor Wardrobe

In outdoor activities where the body shifts from overheating to rapid cooling, Tencel acts as a thermal buffer:

  • During ascent: it quickly absorbs vapor generated by effort.
  • During descent or breaks: it reduces cold, damp sensations.
  • During extended use: it maintains a comfortable feel and limits odors.

Within the AYAQ wardrobe, it reinforces the concept of a single, versatile garment that performs in winter and transitional seasons alike.

5. A Discreet but Essential Pillar of AYAQ’s Philosophy

For AYAQ, Tencel is not a marketing gimmick but a technical lever to optimize a base layer without altering its nature. Combined with RWS merino wool, knit in Italy by an eco-conscious expert, it helps create better, more durable, comfortable, and reliable products—exactly what athletes demand when testing gear in the field.

In dry cold, snow, or continuous climbs, a merino + Tencel knit like the SHIRWALI (men’s / women’s) embodies this vision: natural, consistent, controlled performance designed to support the user year-round.
