One jacket to rule them all! The Solace is the first of its kind in the Alpkit family. Our brand new insulated waterproof is made with damp-proof synthetic insulation that keeps you warm when it's cold, and dry when it's wet. Supremely versatile, the Solace can be used as a walking jacket, a ski jacket, or for instant warmth after a winter swim or ride. It's got handwarmer pockets and a glove-friendly cuffs to accommodate ever-cooling extremities. Made with 100% recycled lining, 70% recycled insulation and a PFC free DWR so it won't leak nasties into the environment. A winter one-stop-shop layer.

Halogen down jacket

Halogen is your featherlight secret weapon. Supreme warmth and incredibly low weight which stows away into its own pocket. 100% recycled nylon with a PFC free DWR and 800 fill-power RDS-certified down.

I'm exhausted and every bone in my body aches. The temperature tanked as the sun went down. 3 days in and I'm racing alone, have been for the last 34 hours. Good call to ride the night as I've got just under 200 miles to go. Halogen is my secret weapon - small enough to carry and unwraps to a warm duvet - put it on and you're gonna smile. No rational person would ever do this but in this moment I wouldn't have it any other way. [Pete McNeil - Sonder rider]

Sierra vest

Sierra vest
Sierra vest

What is it: PrimaLoft® Gold gilet with breathable fleece panels. Full zip for the “am I too hot? Or am I too cold?” days. With zipped chest pocket and two zipped hand pockets.

Good for: working hard on the hills, crags and trails. The Sierra leaves your arms free to reach for drops or holds, whilst keeping your warmth where you need it most.

Sustainability: The insulation is 100% recycled polyester and the fleece panels are 92% recycled polyester, coming from sources like old plastic bottles. The nylon fabric is also 100% recycled and made using fabric scraps and leftover materials from nylon manufacturing.

Designer’s notes: "We were very excited to be able to make one of the first garments on the market using PrimaLoft® P.U.R.E.™ technology. This technology goes beyond using recycled materials, reducing carbon emissions throughout the whole production process – and all without sacrificing any performance!"

0Hiro Jacket

What is it: A superhero 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. It retains over 85% of its insulating ability when wet! It’s got a helmet compatible hood, a full zip and four pockets for stashing snacks (.or hats and gloves).

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. It also uses a completely PFC-free DWR treatment so we can say “see ya later” to potentially harmful nasty chemicals.

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."

Talini Jacket

What is it: A passport to ultimate worry-free warmth; light and compressible jacket using innovative down-imitation fill from PrimaLoft®; a full zip windproof outer jacket or a toasty mid layer. The lightweight, hoodless Talini has got zipped handwarmer pockets and a zipped chest pocket.

Good for: Packable rest-stop warmth throughout the year; an outer layer for cold and windy hill walks; an ultra-warm mid layer when the weather gets really nasty; damp British camping!

Sustainability: The outer fabric is treated with a C0 Durable Water Repellent finish, which is completely PFC-free – no nasty chemicals

Designer's notes: "PrimaLoft® ThermoPlume is the closest you can get to down levels of performance: the synthetic fill is equivalent to around 600 FP and performs better in the wet than even hydrophobic down."

Heiko Jacket

What is it: ultralight and packable PrimaLoft® insulated jacket. Windproof, warm, and damp resistant.

Good for: packing a punch and packing down into its own pocket. Great for changeable weather and throwing in your bag.

Sustainability: The Heiko jacket is made with 100% recycled polyester for its inner and outer fabrics. It also uses PrimaLoft® Silver Eco, a 100% recycled polyester insulation, for the fill.

Designer's notes: "With a PFC-free DWR and 100% recycled fabric and fill, the Heiko is our most sustainable jacket yet. And it's not just any recycled polyester fabric. It's a fabric that feels amazing next to the skin. We've even used it as the lining in our sleeping bags!"

Katabatic

What is it: The jacket you’ll never take off; toasty PrimaLoft® Gold Active fill and air-permeable fabrics for maximum mid layer breathability plus wind-resistance for outer use – two jackets in one! The Katabatic has a simple insulated hood, an adjustable drawcord hem and 3 zipped pockets.

Good for: Working up a sweat, slogging up cold and windy hillsides; under a shell when the weather gets spicy; unrestrictive warmth for scrambling; high effort activities in changing conditions.

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."

Filoment Vest

What is it: Light and packable 630FP fill power down gilet using 100% recycled fabric and fill. The full zip, 3-pocket Filoment keeps your core insulated when weight and freedom of movement are your top priorities.

Good for: Layering up and packing down. Stuff the Filoment in your rucksack for warmth and freedom of movement on the go.

Sustainability: We’re now using PFC-free DWR treatments. They’re non-toxic and don’t build up in the environment, so we’re pretty pleased about that. The Filoment also uses 100% recycled nylon fabric and RCS 100-certified recycled down!

Designer’s notes: “Don’t neglect the importance of your core when you’re trying to keep your extremities warm. Design Tech Gabe always goes for a Filoment vest first when trying to save his freezing hands when winter climbing.”

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 – they really are hard to beat for versatility."

What is it: The cold conqueror; the warmest jacket in our family, with a lightweight ripstop outer to pack neatly into rucksacks and mountaineering-ready features for altitude adventures. It’s got chunky baffles to keep you snug subzero, a helmet compatible hood and a longer cut to keep your bum warm! Despite its next-level warmth, it’s got a great warmth-to-weight ratio and is highly compressible.

Good for: Instant warmth for stationary activities or moving at altitude in extreme cold; belaying in fine conditions; camping on cold, clear nights; between ‘send’ attempts in grit season.

Sustainability: Downtek PFC-free Hydrophobic down and a PFC free DWR-treated outer fabric. Responsibly sourced (RDS-approved) down.

Designer's notes: "Probably the warmest jacket you’ll ever need - you may find yourself wishing it was colder just so you can wear it! We're really proud of little touches like the cosy tricot-lined collar and pockets."
