Arc’teryx Cerium LT Hoody | Review

The hooded version of Arc'teryx's lightweight down-filled Cerium LT is a beautifully made mix of lightness and warmth for use in cold dry conditions.

‘The deceptively warm Cerium LT Hoody pretty much nails the optimum balance between lightweight packability and useful insulation levels. It’s beautifully made too with a sublimely athletic fit.’

Outdoors Magic: Very light, beautifully made, top-notch down, synthetic zones, deceptive warmth, small pack-size, close fit, hood that moves with your head. Superb fit (if you’re athletic)

Outdoors Tragic: Water-resistant down would be nice at this price. Very trim fitting. No hem adjuster, but fits us fine.

Outdoors Grabbit? Yes if you can justify the price. The Cerium LT sits at the balance point between warmth and weight savings. Top-notch down and feathery fabrics keep it decently light, but it’s also warm enough to make it worth carrying in the first place unlike some ultra-lightweight down jackets. The cut is awesomely trim, though uncompromising, and strategic synthetic Core Loft panels add some damp resistance. The hood’s ace and moves with your head thanks to a cord, but there’s no adjustment at the hem. Not a problem for us, but if you’re skinny, it might be for you.

Arc’teryx Cerium LT Hoody – The Stuffing

So what’s inside? High-lofting 850-fill power European white goose down. The higher the fill power, the more insulation you get from the same quantity of down and the stuff here is right up at the top end of the scale, os you’re getting more warmth – or volume of trapped air – per gramme of down.

It’s not water-repellent, which means if you get it really wet, it’ll collapse into a soggy mess and need special drying to restore its performance. Interestingly it’s been supplemented in strategic places with synthetic Coreloft panels, most obviously in the cuffs, to better resist damp in spots that might cop it when worn under a shell.

We’ve see one  very well used Cerium LT where those synthetic-filled panels have lost their loft relative to the rest of the jacket, but we haven’t had that issue with either our original LT test jacket or this hoody version.

Arc’teryx Cerium LT Hoody – Performance

The thing with lightweight and ultra-lightweight down insulation is not reaching the point where the jacket is super light, but not really warm enough to bother carrying in the first place. The good news is that Arc’teryx has pretty much nailed the point where lightness and warmth intersect to optimum effect.

In other words, it’s decently light and packable, but it’s also deceptively warm. What’s the trick? It’s a combination of getting high-lofting, 850 fill-power goose down fill and light but tough, semi-translucent Arato™ 10, nylon fabric and optimising the amount of down in each baffled down compartment. The fit contributes too. It’s beautifully, uncompromisingly trim and athletic for optimum efficiency.

Warmer Then You Expect

All of which means that when you put it on, it’s deceptively warm, significantly warmer than you’d expect from a relatively compact bundle packed into its neat stuff-sac. Not as warm, obviously, as full-on, box-walled expedition duvet, but surprisingly effective for a sub-290g jacket.

That’s helped too by this version of the jacket having an insulated hood, which adds a little more usability. What’s particularly nice about it, is that there’s a drawcord adjuster, which in turn moves with your head unlike many down hoods.

Hydro-no-bic Down

What is interesting is that Arc’teryx has chosen not to use the currently modish water-resistant down, though the outer fabric does have a DWR treatment to shrug off light showers and snow melt. It also gets strategically-placed panels of synthetic CoreLoft in areas that might get damp when worn under a shell like the cuffs and hem.

That makes it best suited to cold, dry conditions – think NOT Scotland mostly – or at least inside when it is damp. To be fair, we’d still choose synthetics or a blend over water-resistant down for any sort of consistently wet weather use.

Close Fit

The fit is beautifully close and athletic, which is a bit of a two-edged sword. It’s efficient, but also quite uncompromising if you’re the wrong build. It also means that you can layer it under a shell just fine, but you won’t be doing any overlayering unless you’re very svelte.

Otherwise it’s all beautifully made and designed in the main. We’ve mentioned the hood already, you also get elasticated cuffs, zipped hand-warmer pockets and a stuff-sac. One point worth noting is that the hem is not adjustable and has no stretch.

For us that wasn’t a problem, the fit was snug enough to work and seal things up just fine, but if you’re relatively skinny, it could be an issue. Try before buying if you can.

Arc’teryx Cerium LT Hoody – Verdict

As you’d expect from Arc’teryx, the Cerium LT Hoody is beautifully designed and made and impressively effective. It packs down small, but carries a deceptive insulation punch that makes it worth carrying in the first place. The hood is a worthwhile upgrade over the standard Cerium LT jacket too.

It’s best suited to cold, dry conditions and indoor use in huts, tents and tea-houses. And while you can layer it under a shell if necessary, like most down jackets, you’ll need to be moving pretty slowly to avoid a steam bath.

Be aware though that the fit is uncompromisingly trim on the one side and the non-adjustable hem can be an issue on the other. Expensive, yes, but an excellent lightweight bundle of optimised warmth.
