New Insulation to Help You Win Winter!

By Mark Roberts

The chill winds of winter are blowing through Alpkit HQ, fell voices carried on the air. What are they saying? We pull off our bobble hats and tilt our ears into the breeze, straining to pick out the words... “New insulated jackets have arrived,” they say, “to help you conquer the cold and win winter...”

We’ve been beavering away the last few months. Actually, we’ve been beavering away for the last year, and we’ve had so many new products to release that we keep worrying we’ve forgotten some.

We’ve got three totally new insulated jackets for this season: new fabrics, new design features, new technologies... did we mention that they’re new?! Ok we’ll stop, before ‘new’ stops sounding like a word and starts sounding like the noise a distressed kitten would make.

With so much NEW (sorry, couldn’t resist), we thought we’d do a quick overview to help you choose between our small, but perfectly formed insulation range.


What is it: A hero below 0°C and master of moist maritime winters – the perfect UK winter jacket; our warmest synthetic layer, using lots of lofted Primaloft® fill and a bomber outer fabric.

Good for: Unbeatable damp-resistant warmth; an outer layer for low intensity activities with a risk of drizzle or sleet; burrowing through snowy gullies in wind-blasted Scottish winter.

Sustainability: 100% recycled polyester liner and 70% recycled Primaloft® insulation. Nylon 6,6 outer to last for seasons and Primaloft® Hi-loft Ultra survives repeated compressions for longer.

Designer's notes:"The 0Hiro is a real get-out-of-jail free card when unexpected weather hits:we've added a 5K/5K waterproof membrane to the outer to give you extra time to get off the hill warm and dry."

Designer's notes: "There's a reason why you see so many people in micro-baffle down jackets: they're the holy grail of warmth, packability and ultralight weight - theyreally are hard to beat for versatility."

Sustainability: Primaloft® Gold Active uses 45% post-consumer recycled content to increase its sustainability without compromising performance.

Designer's notes: "If you own just one synthetic insulated jacket, this should be it.No more boil-in-the-bag feeling when you’ve left it on too long:the breathable fabric and insulation work as hard as you do."
