Those who have bought them have raved about how good they look on the bum and thighs, saying the leggings are as appropriate for the office as they are the gym.

When it comes to the Lorna Jane thermal fabric, you don’t need to worry about being too uncomfortably warm.

Engineered to keep the cold out and your body warmth in, Lorna Jane’s thermal material looks and feels like the brand’s regular LJ Excel fabric — but it has the added benefit of a thermal layer which feels soft against your skin.

With a cotton-like hand-feel and a matte finish, this fabric feels firm and compressive on the outside, and warm and fluffy on the inside.

Lorna Jane say it’s perfectly suited for HIIT, cardio and running.

Those who have bought the pants have raved about them, describing them as a “winter staple” whether you’re out walking the dog at 6am before work or off out for a weekend walk and want to stay cosy.

Lorna Jane are struggling to keep the leggings in stock, but you can currently get your hands on them in all sizes from XXS to XXL.

Many who have bought the tights have paired them with the Off-Duty Sports Bra ($95), making a chic and functional outfit that transitions flawlessly from the gym to running errands.
