⚡ At a Glance
  • Thermal Performance: Isotherm densely packed fibres retain heat and warmth without adding weight
  • Best for: Active women on spring and summer hikes, travel and outdoor days
  • Not ideal for: Very cold winter conditions that require heavier insulated layers

Densely packed Isotherm fibres trap warmth while keeping the fabric light. Quick Dry and moisture-wicking fibres move sweat away and accelerate drying.


Retains warmth without bulk - thanks to Isotherm densely packed fibres

Isotherm uses densely packed fibres that trap pockets of warm air close to the skin while avoiding thick layers. The structure balances insulation with low fabric volume.

Core warmth stays in place during cool-weather activity so layers feel lighter and less restrictive.

Dries quickly on the move - with Quick Dry super absorbent fibres

Super absorbent fibres spread moisture across the fabric surface to increase evaporation area and speed dry times. The inner material moves liquid away from contact points.

Sweat dries faster after exertion, helping to regulate temperature and reduce discomfort on long walks or travel days.

Keeps skin comfortable and dry - thanks to moisture-wicking construction

Moisture-wicking yarns actively pull sweat from the skin toward the outer fabric where it can evaporate. The process reduces trapped moisture next to the body.

Reduced clamminess and fewer chills after stopping, making these trousers well suited to variable activity levels outdoors.
