A while back, I grabbed a Woolverino T-Shirt from Minus33 and I was impressed — so I was excited to give their Algonquin t-shirt in Olive drab a try as well when they offered it. I’ve been testing it for a while now, it’s another instant favorite of mine.


This is a 100% merino wool t-shirt, which is 17.5 micron with a 170gsm weight in jersey knit. Minus33 rates it at 25 UPF, which is pretty standard fare for merino unfortunately.

To the hand, this is a soft and ’normal’ t-shirt weight — so if you have found something like the Woolverino too thin, and the Outlier Ultrafine too thick, this is the weight you likely wanted. I really like the hand feel on the Minus33 wool across all their gear I have tried — it’s done very well and it feels softer than the micron rating might suggest. This is simply a merino t-shirt so not much to say beyond that.

Fit & Style

One thing Minus33 does very well is to note how to expect the shirt to fit, based on your ‘normal’ sizing. This is listed as: “Regular – Standard fit with a little bit of room to breathe, but not too baggy”. I can translate that further to: normal t-shirt fit.

In other words, this is designed to be worn like any other standard t-shirt, and to that end, the cut is perfect. The product photos make it look like it might have an odd cut, but in person it looks just like a t-shirt should, and like all Minus33 goods it runs a little more trim trough the body — which I like, but is worth noting.

It fits me great, and I am a big fan, enough said.


I noticed another blurb from Minus33 on this shirt which I’ll quote in full: “Temperature Recommendations: 30°F to 60°F and up while active, 60°F and up while inactive”. That’s spot on. It’s not super thin, so there will be no worries about it being transparent, but it’s also not super thick. If you think of this as a normal t-shirt, you’ll simply find that it works as designed.

For testing: I wore it all day, slept in it, and then repeated that a day later. I couldn’t get it to stink up after repeating that three times, so it’s on par with all 100% merino shirts for me.

The reason I slept in it: the only shirts more comfortable are my Outlier ones, which cost much more, and are heavier. For me, this is the ideal merino t-shirt weight. It performs like merino, which means it dries well enough, insulates from heat and cold, and does a really good job managing odors. Sleeping in a merino t-shirt feels like luxury to me, and there you go.


The big thing here is the price, at $69 it’s a bargain. Most merino shirts cost more to be this nice feeling with this good of a cut. It’s hard to find something better, let alone at this price.

You can find it here, for $69.

Minus33 is going to be my first stop from here on out for merino goods.
