    Fiery warmth for alpine adventures.

    Aptly named for its ability to withstand severe weather conditions (i.e., SV), the Arc'teryx Thorium SV Men's Down Jacket is a wondrously warm standalone piece for cold, dry conditions, also performing admirably under a waterproof, breathable shell when outside wind and moisture threaten your alpine climb, ski-mountaineering adventure, or cross-town jaunt.

    Using Arc'teryx's Down Composite Mapping technology, the lofty 750-fill European grey goose down throughout the body provides fiery warmth in cold-to-frigid conditions. Realizing that down's heat-trapping loft becomes compromised once wet, Arc'teryx placed Coreloft 100 and 140 synthetic insulation throughout areas prone to moisture build-up from outside elements and perspiration, such as the hood, cuffs, and underarms. The result is a down-synthetic hybrid jacket that retains warmth during aerobic alpine activities, such as ski-mountaineering, alpine climbing, and cold-weather trekking.

    For the jacket's outer fabric, Arc'teryx placed Arato40 nylon, which is a lightweight, yet extremely durable material that stands up to regular use and abuse in the alpine. This shell is finished with a DWR to bead-off outside moisture from seeping through and compromising the down insulation inside. Further contributing to the jacket's high levels of warmth, Box-wall baffles maximize loft, enhancing the down's ability to retain body heat in cold conditions. Other key features include a low-profile, helmet-compatible StormHood, elastic-bound cuffs, drawcord adjustable hem, interior stash pockets, and No Slip Zip front closure.

    • Seriously warm jacket for severe temps while ski mountaineering
    • Moisture-resistant shell sheds snowfall to keep you dry
    • Down Composite Mapping blends synthetic and down for warmth
    • Adjustable hem and StormHood keeps cold out and heat in
    • Includes stuff sack for compact packing in ski and climb packs
    • Athletic cut is semi-fitted to reduce needless bulk and weight
    • Arc'teryx specializes in simple and functional clothing designs
    • Item #ARC00B4

    Very Warm

    • Familiarity: I've used it several times
    • Fit: Runs large
    • Size Bought: Small
    • Height: 5'8"
    • Weight: 138lbs

    This is the best down jacket I have ever owned and very lightweight. I was in Chicago area in early March and it kept me very warm everyday I was walking outside. Jacket is not small and it looks puffy so it can't be a mid layer for those who want it to be a mid layer. It is actually a standalone piece but very great item...no regret

    Super warm

    • Fit: True to size
    • Size Bought: small

    It is. super warm garment I have had. Undoubtly it is my ultimate pieces. With box wall baffles technology, it is really no cold spot, quiet different and huge improve in protection when I need insulation anytime. Great loft restoring, nice packed size, thanks e3D, it is no restricted or limited movement regardless as insulation layer or midlayer nunderneath shell Alpha SL (IT IS REAL! but a bit bulky) and Alpha SV. I recommend this garment .

    Warmest coat my husband has even owned!

    • Familiarity: I've used it several times
    • Fit: True to size

    My husband is ALWAYS cold. He thinks it is cold when the temperature hits 50 degrees. He has been wearing a L. L. Bean down jacket rated for -40 degrees for the last couple of years, and would put layers underneath it to try and keep warm. This year I went in search of something warmer for him. On an independent site I found that they rated the Arc'teryx Camosun Parka as the warmest down jacket they tested. I bought it for him, but he found that it was no warmer than his jacket from L. L. Bean, so back it went. In the meantime, I had purchased the woman's version of the Thorium SV jacket and could not get over how much warmer it was than my down coat.. Bought the male version for him and he loves it. He says that it is the warmest coat he has ever owned. He wears it without any layers underneath, and tells me that it is warmer than the L. L. Bean jacket with the layers. Jacket is lightweight, wind resistant and has a great hood that seems to lock in the warmth. The zipper works really well which makes me think it is going to last as long as the jacket. I am really pleased with both of our purchases and recommend these jackets to anyone who wants a really warm coat. I must also say a word about the customer service at Backcountry. It is Great. I returned two Camosun Parkas to them and an insulated jacket I bought before discovering the Arc'teryx SV jacket, with no questions or difficulty. I will happily buy from Backcountry next time I am looking for any cold weather gear.

    Good Choice

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: small
    • Height: 5'6"
    • Weight: 110lbs

    Bought this jacket for my son in college. He wanted a light weight, packable, hooded winter jacket for the East Coast weather. Replacing his NF 700 fill jacket. The fit is perfect. He is 5'6" and sleeves fit ok, not too long. The jacket has a nice shell that is not shiny. There are pockets. It is a little bit puffier than he wanted but he is keeping it. We chose this over the Mountain Hardware because it has a less puffy fit and is not shiny on surface. Has not worn it yet so I will update on the warmth.

    Any thoughts/experience on with how this jacket compares to a Patagonia Down Sweater in terms of overall warmth?

    I recently moved to New England and am looking for a warmer down jacket (I own the patagonia down sweater and have loved it). Low temps in my region were often below 0 F and occasionally down to -20 or -30 F last year. The jacket will be used for skiing/backcountry and clearing snow in the mornings. I am hesitant to spend the $ if this piece wouldn't be much of an upgrade over what I currently have.

    Appreciate any info or recs you can provide.

    What is the main difference between the Thorium SV and AR models?

    Do you think the Thorium SV would be warmer than the Cerium LT Hooded Down Jacket ?

    Best Answer

    Hey Daniel.

    The Thorium SV will be about 3 inches longer, it also has a box wall construction to eliminate cold spots and increase loft. The SV uses 750 fill power down with Coreloft 100 and 140.



    The AR baffles are sewn through and uses 750 fill power down with Coreloft 80 and 140. It will also be about 7.5 oz lighter in overall weight than the SV.

    Is the only difference between the Cerium SV hoody and the Thorium SV hoody down fill weight? Or is one a slimmer cut than the other?

    Eri,



    So the major difference for insulation will be that the Cerium SV utilizing the 850 power fill and the Thorium is utilizing the 750 power fill.



    Fit will also be different.



    Thorium SV: Athletic

    Cerium SV: Trim



    The Thorium SV is also going to be roughly 6 oz heavier and will have a slightly longer center back length.

    The Cerium is designed for light-weight warmth using 850 FP down and a much ligher shell fabric. The Thorium is designed for balanced durability and warmth (with less concern for minimizing weight) with a MUCH tougher shell fabric and still high quality 750FP down. This has nothing to do with whether one is warmer or not. The Cerium is a slim mid-layer fit. The Thorium has a belay fit and is quite roomy. If you're using it on the street and you're not a mountaineer/backpacker caring about minimizing his pack weight, you may be better served by getting the more durable Thorium.
