- How do these fleece trousers keep you so warm?To keep warm from head to toe, we suggest these fleece leggings. Discreet under trekking trousers, their brushed knit lining can trap air to act as an insulating barrier and maintain body heat.
- Breathable fleece trousers?To ensure that these fleece leggings remain comfortable, even during intense activity, we’ve chosen a breathable fabric that wicks away moisture and perspiration. Score: you stay dry and comfortable whatever the situation.
- What is the RET index?The breathability of a fabric is measured by its evaporative resistance RET (ISO 11092 standard): The lower it is, the more breathable the fabric. Examples: RET< 9 (very breathable), 9 < RET < 12 (breathable), RET > 20 (low breathability). These fleece leggings have a RET rating of 6.3.
- What sizes are available?These fleece leggings are available in a range of sizes: - XS / W26 L30 - S / W28 L31 - M / W30 L31 - L / W33 L31 - XL / W35 L31 - 2XL / W38 L31
- How to look after these fleece trousersWash your fleece inside out at 30° on a synthetic cycle. Limit the spin speed to 1,000 rpm to avoid damaging your fleece. To preserve the fabric, avoid tumble drying.
