Equinoxx Stage 3 Ultra-Thermal

I had been wearing this shirt as a base for a while and was thoroughly impressed with its day to day comfort in the basic cold weather, between -10 and -25 degrees Celsius or so, which of course was in and out of the vehicle, with relatively short exposure times outdoors during my shifts. However, on one occasion, its performance particularly blew me away. I was wearing this shirt as a base thermal with only a light fleece overtop, and then my SBA, during a colder night shift at around -37 degrees Celsius (almost -35 F). A coworker was operating a snowmobile on a stranded UTV call patrol, and grew too cold to continue, but we were still 15 minutes from home base. I volunteered to give it a try, wrapping an extra coverage around my neck area, fully expecting it would last not even a minute and there’d be no way to continue. What followed was me being able to operate for about half the distance, stopping once to warm up briefly (mainly for my legs), and then continue the rest of the way. I was absolutely shocked at how well this piece performed with what was such an extreme cold without even factoring in the wind chill that would have been produced by operating the snowmobile in those conditions. When we got back, my partner felt my outside layer, which obviously was cold to touch, but when I told him I was a bit chilly, but not cold feeling underneath on my upper body area, he was shocked. I’m not sure how they have managed to get such cold performance out of such a pliable and non-restrictive material, but they made a believer out of me on that cold night patrol. Keep up the great work 221B!

This shirt is better than even advertised. Even though I’m in Florida, nights shift can be cold. This shirt is not bulky, and is WARM. I bought another after the success of the first.

Love the base layer as far as comfort goes. Fits as described. I don't believe its quite as warm as described. My first day wearing was 10 degrees above and I still feel like I need an additional layer. The shipping was very slow almost a month before getting here. I did speak to helpful lady named Richelle who was helpful from a customer service aspect.

Ordered two of these shirts after being given the recommendation by a coworker. Took me exactly a month to get my order while waiting to receive my order I reached out to customer service multiple times with no response. Once I got my order I only received one shirt. Called customer service said nice again with no response. Called the owners number. He answered and was very apologetic about the issue and said he would let the warehouse know immediately.

Now the shirt is well worth the price. It keeps me warm on cold nights. Can’t wait to receive my second one!

I work for a midwestern department where we regularly see sub-zero temperatures with windchill plunging it to the -40s (F). Normally, my layers are 3.0 base layer, uniform shirt, coat, and external carrier. I absolutely despise wearing a coat under my vest.

After some brief shipping issues worked out with some fantastic customer service skills by 221B, I received the base layers a day before we had our deep freeze and figured I would REALLY put the base layer to the test. I took the coat out of my layers and worked patrol with just the base layer, uniform shirt, and external carrier.

On getting my patrol unit ready, I noticed I was actually starting to break a bit of sweat with it being between -10 and 0 degrees (no wind) and besides some minor chills, it really felt no different than being outside on a cool summer night to me (60-70 degree comparison). I worked like this for approximately 3-4 hours at which point windchill dropped the temperature to in between -30 and -25 degrees with a cutting wind. The wind cut through the base layer like a knife but credit where its due, this is the type of cutting, cold wind that would cut through ANY base layer. Even with this wind, the cold I experienced was more of an uncomfortable cold and not an unbearable, "I need to put a coat on NOW" cold. After I put just a windbreaker on, I had no issues with the cold. With my 3.0's, I had to wear an actual coat and not a windbreaker in this chilling cold wind.

The following nights I worked in -10 to 0 degree weather and even with light winds (that were not cutting) taking windchill to the -15 range, I did not need a coat. So I think I have definitely pushed and tested the limits in the most extreme way of this base layer.

Overall, these will be my new extreme weather base layers as just in the brief amount of time I've used them they have proven themselves to be extremely worthwhile in the extreme cold we have here. I will be recommending the products to any new trainees we hiring on and have been directing shift-mates to the products as the majority of them also despise wearing coats.
