I tested this jacket with the Trew Trillium Bib

Fit

The Trillium jacket comes with a relaxed fit that had plenty of room to move. I love the length of the sleeves, and the longer length in the torso. Makes for a very comfortable jacket for snowboarding.

Hood/Helmet Compatibility

The hood has a nice fit over my Giro helmet. Good enough that I would even snowboard with the hood on. Which I never do. The peripherals are great and there’s enough room to turn my head from side to side without restriction or discomfort. For me, it is a great fit over the helmet.

Warmth

With 60g of insulation throughout the jacket, it is warm enough for colder riding temps, and there is plenty of room to layer underneath as well if needed. Even though it is fully insulated, the jacket isn’t bulky at all.

Powder Skirt

The Trillium jacket comes with a removable powder skirt that fit well when I tested it out. It stayed in place while snowboarding, and was comfortable as well. There is no jacket to pant interface, but the elastic on the powder skirt comes with a silicone backing that helps keep it in place while riding.

20k Waterproofing

I got to test this jacket out in some very wet weather up in Palisades Tahoe. The weather was freezing sleet at first and then it just turned into rain. I was working an event so I spend 3 hrs in the morning completely in the rain with no breaks. This jacket kept me dry the whole time. The waterproofing is a bit different, as the material absorbs the water first, and then evaporates the moisture. As opposed to just rolling off the material. So the jacket looked wet, but the moisture never passed through the first layer of the outer shell. The only down side to this in the wet weather, was the jacket did get a bit heavy when it was fully saturated.

However, it dried incredibly quick when I went inside for a lunch break. So fast, that as soon as I turned on my heater in my van, the moisture instantly started evaporating off the jacket and it was basically dry by the time my lunch break was over. (The image below is from the Trillium bibs, but they are the same material)

The cool part of the jacket material, is that it has really good waterproofing without feeling like a waterproof jacket. It is quiet when you move around, and has more of a soft/flexible feel as well.

20k Breathability

I also tested the Trillium jacket out in some warmer winter weather. And even though it is an insulated jacket, it still breathes well.

Pockets

If there’s one thing I appreciate in women’s outerwear, it is functional pockets. And lots of them. This jacket comes with two hip pockets (that are generously big), one pass pocket on the upper arm (with a waterproof zipper), one outer chest pocket that fits my iPhone 14 with no problems, a smaller inner chest pocket (for a pass or small snack, and a catch all net pocket on the inside as well. Plenty of cargo space to carry all the things and then some.

Overall

The Trew Trillium Women’s Jacket could be great for someone who rides in colder winter conditions, wants a relaxed fit without looking too baggy, and likes to go out on storm days as well.
