When it comes to cut Arc'teryx really have worked their magic, passing the basic 'lift test' with flying colours - i.e. raise your arms to climb and the hem simply doesn't lift. In this review, that's a rare accolade. Weight aside, this is what we liked most about it: it just fits. This makes climbing in it feel like a dream, simply because it's akin to wearing a warm, fitted fleece. That said, it does size accordingly and a Medium is definitely on the snug side of the spectrum. Starting at the top, the Resolute features a fully adjustable, helmet compatible hood with a stiffened peak. Hood adjustability is taken care of with drawcords, meaning a nice snug fit can be achieved both with and without a climbing helmet in place. It can also be rolled away when not required. Bluesign approved fabrics / Responsible Down Standard approved / PFC-free DWR treatment / premium 800 Fill Power goose down / Mimic Platinum insulation / 3-layer zoned waterproof-breathable face fabrics / hydrostatic head: 15,000mm / moisture vapour transmission rate: 10,000g/m2/24hrs / front panel straps / helmet-compatible hood.

To give that price some context we then looked at all of the products available from Go Outdoors in the Insulated category. We found 48 items in total. What’s the price of Insulated?

Fill power: This refers to the thermal efficiency of the down fill. The lower the number the lower the efficiency. Anything upwards of 700 tends to indicate good thermal efficiency. The material the product is made from is often a sign of the quality for Insulated. Take a look at the product details over at Go Outdoors to get a feel for this. At 430g (size L) the Microlight Summit is towards the heavier end of this review, but we think this is a fair reflection of its long cut, fill weight and features. This one is warmer than most. Increased demand and a need for profit on animal products does not yield ideal conditions for animal welfare. We’re particularly impressed by the eco credentials of the Nordic Expedition as it’s made from bluesign approved fabrics, the down fill is certified by the Responsible Down Standard and the DWR treatment is PFC-free. What’s more, Haglöfs as a brand is a leading member of the Fair Wear Foundation and is a certified climate-neutral company.

During our tests, this felt luxuriously warm and incredibly lofty. It’s like wearing a big down sleeping bag. The material felt a little on the brittle side, but it still held up throughout a testing period. Step four: If using Nikwax Down Wash Direct, place 100ml in either the tray or directly into the washing machine inside a small pot/ball. If you choose to use another washing product, place the appropriate amount in the machine in the same way. What was once the Arc’teryx Cerium LT is now the Cerium Hoody. There are a couple of updates, with new colour ways, different ingredient fabrics and perhaps most notably a new liner that’s derived from natural materials (castor bean oil). It’s mainly stuffed with 850 fill power responsibly sourced down but there’s also synthetic fill strategically placed in areas that are more prone to moisture, including the cuffs, shoulders and armpits. Water resistant-treated down is common nowadays, and we think that for UK use in particular it's well worth seeking out since it allows the down to maintain its loft (ie. go on working to insulate) for longer in damp conditions. We've considered the use of hydrophobic down a plus point in this review.With the elastic snugged up around the bum there is no hem lift at all when the arms are raised, and no pull around the armpits. Even with the elastic not done up at all there is minimal hem lift. That might be the Fowler influence - they must have designed the Ramche very much with climbers in mind.
