    Nucleus Pull-On Fleece Jacket

    When you've got one hand in a crack of cold granite and the other reaching for the next, the last thing you want is for your clothes to hold you back.

This midweight fleece has plenty of stretch for chilly fall climbing routes and comfortable layering on the ski hill. Its oval-grid design manages moisture to keep you dry through your layers while enhancing breathability and temperature regulation.

    Decent fleece minelayer

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'1"
    • Weight: 200lbs

    I bought the first of these last year from a little shop in Cambridge while on a UK trip. I liked it well enough to look for a second here in the States. This review covers both of them.

    Fabric. The new pullover seems to be a slightly different fabric from the one I bought in the UK. Both are grid fleeces, more or less the same thickness, both have worked well in use - warm, quick to dry, a little stretch... I don't see a practical difference in performance, and haven't had either long enough to assess durability of the fabric.

    Cut. I like the high collar for those damp, blowing days where I want to conserve every calorie of heat. Good chest pocket positioning for me, and the pocket is big enough to swallow my phone, or a couple energy bars, or a hat... Plain sleeve ends with no thumb loops. I like that, since I wear this pullover as a casual sweater as well as for outdoors use. Deep chest zipper, which vents well and makes it easy to put on or take off. The overall cut allows for movement without binding or riding up. Nice... Both garments appear well sewn by the way.

    Fit. I called it "True to size", with the caveat that I'm probably a bit, uh, bulkier than the typical high-energy Rab user. Or it could be that I'm sort of between sizes. Rab's Large goes to 43" chest, where my chest is 44". Thus, my Large Nucleus is really snug; only the great action cut makes this one usable for me. My XL has much better body fit, but both the torso length and sleeve length are excessive - workable but excessive. I have the same problem with Arc'teryx gear, and for the same reason.

    The Nucleus pullover strikes me as an alternative to Patagonia's R1 Flash pullover, except the Patagonia garment fits me perfectly where Rab is less good for me. Try it on - if it fits you you'll like it. On any comparison except fit this Rab pullover is as good as the R1, which to me is the standard for the type.

    Love the Fabric but runs VERY Small

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Large
    • Height: 5'8"
    • Weight: 165lbs

    This is a lightweight, super warm fleece, but it is an athletic cut pullover. I am
    5' 8" and about 165 lbs and was planning on using this over a long-sleeve base layer top, but I could barely get it on (size large). I don't remember this being advertised as an extreme cold base layer top. I'll be returning it. I'll also add that the arms were just slightly too long for my liking, but the length was just right for me (but too short to tuck in - making the case against using it for a base layer).

    Great cut, style and very warm

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 5'11"
    • Weight: 190lbs

    I'm a big fan of Rab products and this fleece is no exception. I've used it for both skiing and running in cold conditions. It wicks moisture quickly, looks fabulous, is very comfortable and a slim fit.

    I use it primarily as a mid layer fleece which keeps me toasty warm with a thin base layer and shell. I suspect I'd need an insulated jacket for colder days, but this is good down to -5 centigrade or the low twenties. I got the zest to match the yellow and grey of my shell. I wash it in the machine and lay flat to dry. Excellent purchase although a little expensive at regular price. I wouldn't hesitate to buy another one as the quality is superb.
