⚡ At a Glance
- • Wearing Comfort: Fleece-lined microfibre fits close to the skin without chafing, supporting movement and insulation
- • Best for: Active commuters, winter runners, gym users and anyone needing a warm base layer
- • Not ideal for: Heavy-mountaineering or situations that require thick, multi-layer outer insulation
Fleece-lined polyester and spandex blend balances warmth with a second-skin fit. Moisture-wicking fibres reduce clamminess during higher intensity activity.
Reliable Warmth – Thanks to micro-fleece lining
Micro-fleece made from a 92% polyester and 8% spandex blend traps a thin layer of warm air close to the skin while staying lightweight. The low-bulk structure retains heat without adding excessive thickness.
Core and leg muscles stay warmer during outdoor sessions and cold commutes, reducing the need for bulky mid-layers.
Freedom of Movement – With four-way stretch construction
A four-way stretch knit, combined with advanced seam placement, allows the fabric to expand and recover in all directions while maintaining shape. An elastic waistband holds the fit without digging in.
Full range of motion for squats, lunges and long runs, while fitting discreetly under outer trousers.
Dry Comfort – With moisture-wicking fibres
Breathable polyester fibres draw sweat away from the skin to the fabric surface where it evaporates, reducing the wet, clammy feeling. The breathable construction balances insulation with ventilation.
Remains comfortable during intense workouts and overnight wear, helping to prevent chills after exercise.
