The Beta SL Jacket – our lightest Beta – is built for mountain realities. Highly versatile, it’s carefully designed to deliver complete waterproof, windproof, breathable protection without sacrificing lightweight packability. Its innovative GORE-TEX ePE membrane is light, strong, and PFC free. C-KNIT backer technology improves comfort and breathability. The helmet-compatible StormHood protects without compromising vision, pit zippers ventilate, and a RECCO reflector can aid in search situations.

This product is free of intentionally added PFAS.

The new ePE membrane technology is lighter and thinner, but just as strong and durable as the materials we used before.   You may notice the face fabric “wetting out” slightly faster in products with ePE membranes, but rest assured this does not affect the waterproofing of the membrane itself. If you notice the fabric wetting out faster than you’d like, simply wash the jacket and dry it to remove the oil contamination and bring the DWR back to its full power.

Product tip: Looking for the Beta LT or Beta Lightweight? They’re now the Beta SL. The Beta LT has a new name and design. The Beta Lightweight is the same great jacket—new name.

How to care ?

Before Washing

Turn clothes inside out → This helps protect the fabric and preserve prints or logos.
Check the labels → Some fabrics require special care.
Shake off dirt → Especially for hiking clothes, remove mud and debris before washing.

Washing Instructions

1. Use cold or lukewarm water (30°C max)

  • Hot water can damage synthetic fibers and elastic materials.

2. Choose a mild detergent

  • Avoid fabric softeners, as they can clog breathable materials and reduce moisture-wicking properties.
  • Prefer liquid detergent over powder to prevent residue buildup.

3. Use a gentle wash cycle

  • A delicate or sportswear program is ideal.
  • Do not overload the machine to allow proper rinsing.

4. Hand wash if needed

  • For delicate items (compression wear, technical fabrics), soak in lukewarm water with a bit of detergent, then rinse thoroughly.

Drying Instructions

Air dry whenever possible

→ Hang clothes in a well-ventilated area.

Avoid direct sunlight

→ It may weaken the fabric and fade colors.

Do not use a tumble dryer

→ High heat can shrink or damage sportswear elasticity.

Extra Tips:

  • Remove odors naturally → Add white vinegar (½ cup) or baking soda (1 tablespoon) to the wash.
  • Wash sportswear separately → Avoid mixing with cotton clothes, which can transfer lint.
  • Never leave sweaty clothes in the laundry basket for too long → Wash as soon as possible to prevent bacteria buildup.
