This 100% Merino feels soft, but it's not fragile. Fibre for fibre, it's 6 times stronger than cotton.
Much better to leave merino to do what merino does best. You can freshen Purefleece® simply by hanging on a line in the breeze.
PureFleece® - 100% natural, start to finish.
PureFleece® skips it entirely.

Each PureFleece® features a natural rubber cinch cord at the hem that's designed to last up to 3 times longer than the usual polymer based cords. Even in the smaller details, nothing beats nature.
The PureFleece® 100% Merino Quarter Zip, available in Loch Blue, Slate Grey, Moss Green, River Blue and Limestone.
PureFleece® is 100% Merino. Zero plastic, by design. And it performs way better than anything synthetic.
Most outdoor brands are simply switching to recycled polyester instead of tackling the problem. Recycled or not, it's still plastic, and it still sheds millions of plastic particles into the air around you and the environment.

Every PureFleece® is designed to hold up on the hill, not just look good leaving the shop. We wear tested with the people who spend their weekends and their nights out in the worst of it, to get feedback no lab test can replicate. It also means we get to give something back to the teams who keep the mountains safe for the rest of us. £1 from every PureFleece® sale goes to Scottish Mountain Rescue
Check the label. PureFleece® is certified pure 100% Merino, no blends, no recycled wool and elastane hiding in the mix.

PureFleece® absorbs up to 35% of its own weight in moisture while still feeling dry. That's lanolin, the natural wax in Merino, doing exactly what it does on a sheep in the rain. No coating, no membrane, no synthetic finish.

PureFleece® is spun from 20 micron Merino, less than half the width of regular wool. Soft enough to wear straight against skin, no base layer needed.
We also skip the Superwash finish most merino brands use, a polyester coating that stops the fibre felting. Ours stays 100% natural and Woolmark certified throughout.
There is a way to improve merino fleece. So we did.
Most fleece is knitted. Ours is woven, on Rapier looms, at one of the world's finest mills, here in Britain. It takes longer and costs more, but it's what gives PureFleece® more loft, more weight and far greater durability.

Most merino fleece is knitted, but often stretches out of shape and snags easier than polyester fleece does.
That's the gap we set out to close. Every PureFleece® is woven instead, on Rapier looms, at one of the world's finest mills, here in Britain. For a true durability that lasts season after season.
PureFleece® - Same merino fibre. Completely different fabric.
