Heavyweight Leggings 360g
Men's Merino Wool Heavyweight (360g) Leggings

Size Guide
Colour & Size: Black
Steel Grey

Made from our superfine merino wool in a heavy weight knit, these 360g thermal leggings are the ultimate lower body base layer for combating the most extreme conditions and are a perfect match for our 360g Long Sleeve Crew Neck Top.

These leggings will keep you super warm no matter what the weather throws at you! As worn by many of the Tasmania, Australian Police Search and Rescue Helicopter Crew. Take them on your next hike or wear as yoga pants. 

You can also look at fleece leggings if the purpose is to keep very warm in non-extreme situations like for around town and home. They are very warm and stretchy and feel a lot lighter to wear than the 360g leggings.

These Legging are nice and long so fit all leg lengths of men. For shorter men its no problem as they just bunch up a little and work perfectly.

Made in Tasmania, Australia. Inspired by nature.

Exceptionally good

The leggings and associated top are without doubt the most comfortable and effective thermals I have worn. I have worn various types over 40 years of fly fishing in the highlands of Tasmania, but also during 17 expeditions to the Antarctic. The Smitten thermals are much warmer, and better fitting than even a well-known, popular New Zealand brand. I wore the Smitten thermals over three days fishing in very cold winter conditions, frozen ground, ice around the lake, water 4°, air temperature dropping to zero at sunset. The thermals kept me very warm, including fingers and toes because body, arms and legs were appropriately warm. The thermals kept their shape and firm fit, no sagging, and felt like a second skin. I didn’t even notice I was wearing them.


Very fast delivery and good quality of product!

Brilliant....... great customer service and great item. Im very happy. Glad that my money is staying in this state and helping pay Tasmanians.

Thanks so much Patrick! Really appreciate you taking the time to write a review :)


Warm and soft but these tights have a single centre seam with no gusset so they aren't as comfortable or flattering as you'd hope. More for at home or under other clothes unfortunately.


These are an excellent quality product. Well woven, warm and most comfortable - a credit!
