YMMV Review

The Outdoor Research Tremor Pants are a full featured Gore Windstopper pant. Outdoor Research makes clothing and gear designed to get outdoors. All their gear is tough wearing and thought out for adventures.

Design ★★★★☆

The Outdoor Research Tremor Pants are made for hiking, climbing, and skiing.

Fabric and Seam Tape

They use Gore Windstopper softshell throughout to block wind and be water-resistant. The main body of the pants has a tricot (thin fuzzy) backing while the seat and knees have a thicker fleece backing. The pants are fully seam taped to increase its water-repellency. All the zippers are water-resistant as well. The fly has a snap and a double zipper so you can open it whatever direction you please. For a better fit, the pants have a gusseted crotch and articulated knees.

The pants feature a two zippered hand pocks and a zippered thigh pocket. There is a thigh-length side zipper for venting on both legs. These vents can be opened either direction. The cuffs feature a mid-calf length zipper to help with taking on and off over boots. At the bottom they are secured with snaps and have a drawcord to tighten them when needed. Inside the cuff there are zip-out internal mesh gaiters with elastic grippers at the bottom. The gaiters also have a Velcro opening with two options for tightness. The inside of the pant legs at the cuff have reinforced Schoeller ankle scuff guards. At the bottom of the ankle cuff there are also Grommets for on instep lace. The last of the many features of the Tremor Pants are connection points for the optional suspenders. As you can see, these pants are feature packed.

Cuff & Gaiter

Fit ★★★★☆

I have had an issue with most Outdoor Research pants. They make their pants fit a little trimmer than I like. They do this to keep the excess bulk down but I have always been a fan of looser fitting pants. The Tremor Pants are Outdoor Research’s standard fit. Unlike some of the other pants they make, these fit me well. The pants are built to layer over a baselayer and even a midlayer. For this reason they are a little bit roomier, but not too loose. The gusseted crotch is a nice feature to help the pant feel unrestricting. It keeps the legs from riding up when you move your legs. I also like the articulated knees, the pants just move well. The Tremor pants have a little bit of vertical stretch to help with comfort as well. I do not use the suspenders and have no issue with the pants staying up. There are belt loops if they are needed. The inseam length is perfect for me. I normally wearing these with boots and these stay down well and I can tighten the cuffs if needed.

Performance ★★★★½

The Outdoor Research Tremor Pants have been a go to pant for me.

Pockets & Vent

I find they are warmer than regular Gore-Tex pants and this allows me to not have to wear a base layer except on the colder days. The windstopper fabric does block wind and the lofted backing is soft and warm on the inside. I really like softshells because they are more pliable and quieter when wearing. The one drawback to them is the weight, softshells are generally heavier than other snow pants. I have used these pants for hiking, skiing, and snowshoeing. They have performed well on all occasions. They breathe well and with the thigh vents are able to accommodate a lot of conditions. I have not thoroughly tested their waterproofness yet though. I have used them in wet snow and snow mixed with rain and had no issues with water getting through.

As mentioned above, they are on the heavy side and a bit bulky to pack. I think they would be ideal for trips where you need to wear snow pants the whole time. I do not think they are ideal for stuffing into a backpack due to their weight and bulkiness. The ankle scuff guards are tough and have not worn yet. The internal gaiter works well too. I had one issue with these when the internal gaiters were removed. I had and external gaiter on and the pressure from the gaiters caused the internal zipper to rub my leg raw. This should be easily remedied with looser external gaiters or longer socks. Other than that, the pants have performed great.

Overall ★★★★☆

I have been impressed with the Tremor Pants. The performance was good, if not better than expected. I would recommend them for any cold weather adventures. While I have tested them in everything but a downpour and I feel like they would be adequate even there. I would not like to use them as a just in case rain pant on a backpacking trip due to the weight. But other than that, they are my go to pant. They are tough wearing and can brush off rocks and other abrasive materials without issue (except cat claws, that leaves small fabric pulls). At $275 they are on the steeper side, but they are full of features and earn their price. As always, your mileage may vary.
