Don't let the name mislead you: the Millet Belay Composite Jacket won't leave you grounded and hauling your expedition buddies up the face. Sure, a healthy dose of Primaloft insulation will keep you toasty when you do pull belay duty, but a lightweight and weather-resistant design performs just as well when it's your turn to take a crack at the crux pitch.

Nice for hiking with a light pack

  • Familiarity:I've used it several times

As some have said, minimal fill in the chest and lower torso areas make this really an exertion piece. Very comfortable with a 30+ lb. pack and hiking. Light fleece on the inside and up through the hood helps with a soft touch with hood on for those colder and windy days. The pit-zips are great and HUGE. If you are in high exertion mode and need to dump a ton of heat, these things open to your hips.

The DWR doesn't seem very effective from what I've seen thus far right out of the box. My 10 year old hard shell's DWR is more effective even without a re-coat in the past 2-3 years. My biggest gripes:

- wish it were a little more packed with Primaloft since you could dump excess heat with pit zips

- the main zipper and hood adjustment cords are really close to other when fully zipped. I've had more than several occasions trying to pull down my zipper from my face and accidentally tugging on a hood adjustment with gloves on.

- not a gripe, but more a warning: when the pit zips are down all the way, they extend down to the same height as the start of your side pockets. If you're moving quickly and trying to put something in your pockets (especially with gloves), you've got to be a little more careful to get them actually into the pockets rather than have them pass straight through the pit zip and onto the ground.

I like the jacket, but find it's more a niche piece than all around. For what it's worth, my family calls it the "turtle jacket" because the baffle pattern looks, well, kind of like a turtle shell.

Great all-around jacket

    I bought this jacket for my boyfriend for Christmas and he loves it. When it's cold out, he wears it all the time, not just climbing. It works well for him when climbing because the pockets lie above where the waist strap of the harness sits. Also it has pit zips for ventilation. good solid material hasn't ripped yet. I definitely recommend this jacket.

    Good jacket with lame zipper

      I always wanted a Millet jacket to add to my collection but they are somewhat expensive. I decided to take a chance on the Belay Composite and in general I like it. It's as described a sofshell upper married with a primaloft lower. The softshell is par for the course in this price range - light fleece on the inside, water resistant (but not waterproof) and stretchy. The primaloft insulation is minimal fill; this is not a jacket to wear standalone on very cold days.

      The fit is very nice though. I am 5-9", 170lbs, 33 waist and a Medium fits on the money as a standalone jacket. I could squeeze in a light fleece if I wanted a snug fit. Here is what annoys me though - the zipper. It's European and reversed - you slide the zipper in on the right side. Just plain awkward for us used to the other way.

      I like it, but it's more of a nice to have jacket than a need to have.

        This jacket does it all !!!!!!
        Once again Millet fit is amazing on this piece.
        I use this jacket for pretty much everything: from very cool days to hard climbs. The insulation keeps me very warm and the soft shell on the shoulders and arms keeps me totally dry. The side vents zip help to regulate core temp. I feel that this jacket was design For any type of adventure in the mountains.

        Will this jacket work well as an insulating layer, as in under my softshell/shell? Will the hood fit under a helmet?

        I'd say decently as an insulating layer. The hood is pretty small - I wouldn't think a large helmet would fit well under it, although it would be pretty snug... under my Arc'teryx Theta AR with drop hood, it feels adequate down to mid 20's with mild to medium exertion, but the double hoods are kind of annoying.

        Can anyone compare this to the Patagonia Rubicon Rider Jacket? Thanks.

        Best Answer

        The Millet Composite has primaloft in the body, meaning that the core of the jacket is warmer than the rubicon, but it simply has stretch woven sleeves, with no insulation. In turn, the Rubicon Rider is completely filled with a not-so-great quality recycled insulation, and has waterproof wear panels on the shoulders and hips. Both are designed for different purposes. Really depends on what you need it for.
