Made for higher output and warmer days, our lightest base layer crew is made for wear all year round. The ultralight 150gsm fabric combines Merino wool – known for temperature regulation and odour control – with super-soft TENCEL fibres and nylon for durability. Betaspun technology combines the fibres into a single ultralight yarn that feels comfortable on your skin, withstands abrasion, and resists pilling. Low-profile seams and the ergonomic design provide comfort on the move.

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.
