Boasting lavish comfort, the Icebreaker Tech 260 is an incredibly warm base layer. Loaded with 260-g of 100% Merino wool this cozy contender will keep you toasty through the chilliest months of the year. Not only is it warm, but its thermoregulation is exemplary. It provides fantastic breathability while hiking uphill and ample warmth while skiing down. The fabric wicks away moisture and efficiently transfers it for evaporation, so it doesn't sit in the fabric, ultimately keeping you dry and comfortable. It performs well in a range of activities from hiking to skiing! Our only caveat is that it's not super durable and layering takes a little extra effort. Aside from that, this midweight base is perfect to wear as a layer or on its own.

Our Analysis and Test Results
Layer or wear the Icebreaker Tech 260 on its own for all-day comfort. The 100% Merino wool construction is excellent at thermoregulation while the heavier weight provides more warmth on colder days. It's suited for cool weather use that can extend to all seasons. Enjoy!
Featuring 260-g of 100% Merino wool, this is an exceptionally warm top that is also capable of offloading heat. The tightly woven fabric provides some wind-resistant when worn on its own, while the fabric does a great job wicking and keeping moisture away from the skin. The thicker fabrics add to its overall warmth, scoring it as a high performer in this metric. With a variety of weights available, it's a great option for wear in Polar temperature, layered appropriately in its own system.
Keeping with the pattern exemplified by 100% Merino wool base layers, the Icebreaker Tech 260 is quite breathable. When wearing it while ski touring, we experienced bouts of warm and cold temperatures, sweating while moving uphill and shivering on the way down. In both situations, this top kept us comfortable and dry - venting and breathing on the uphill while locking in warmth on the downhill. As a result, it offers a wide range of thermoregulation…it's capable of off-loading heat with the activity picks up, and can keep you warm with the temperatures plummet.
Comfort & Fit
Similar to other Merino wool products, the 100% Merino wool fibers are soft and comfortable against the skin. Featuring no-itch properties and a relaxed athletic fit, this shirt is a favorite among our testers. The size is true to fit, but unfortunately, it doesn't have much length. As a result, it rode up a little easier than other layers, but it didn't constrict through the shoulders or bust. While it's not as stretchy or tight as other base layers it did fit most of our testers. It can be worn all day and for multiple days on end.
Like all Merino wool shirts, the face fabric is a little grabbier than synthetics and doesn't slide as easily over other layers. We found that it grabbed tighter mid-layers, but performed just fine under jackets. It does accommodate a tank top or t-shirt for wear underneath during the warmer months.
While this layer doesn't absorb a whole lot of water, its drying rate is a little lower than the rest. The top itself, surprisingly, doesn't absorb a lot of water which is not the pattern for most 100% merino wool tops. That said, with less water to evaporate during our drying tests, it still took 90 minutes to dry. As a result, the drying rate is a little lower than other tops. In the field, it seemed to do a great job wicking away moisture and didn't notice it lingering in the fabrics. Overall, despite its lower drying rate, we'd still recommend it for all conditions. Though if you seek a top that dries faster, take a look at a synthetic option instead.
Inherent to the properties of Merino wool, this is not the most durable base layer tested. The softer face fabrics can grab and snag trees or other sharp objects while hiking and the fibers will wear away faster when exposed to high-friction activities like off-width crack climbing or spelunking.
While it didn't show any significant signs of wear and tear during our testing period and is more than suitable for casual activities or wear around town, we noted a couple of stitching fly-aways and a little pilling of the face fabric. As a result, we would contest that when taken care of, this base layer will last you for a long time.
With its wide range of thermoregulation and comfort, it's a perfect option for all-day wear through all four seasons. We seriously think you could do anything in this top! Our only suggestion is to leave it at home if you plan on seriously exploring caves or canyons as the friction will most likely burn a hole through the fabric. We also wear a thinner top when the temperature gets warm.
At $110, this is one of the most expensive baselayers tested. While this Merino wool option stands out for its great craftsmanship and warmth, its performance isn't nearly as high as other cheaper options. As a result, it's not the best value and there are some better priced Merino wool contenders out there.
The Icebreaker Tech 260 base layer stands out for its ample warmth and a wide range of thermoregulation. Pack or wear it on your next wild adventure into the wilderness this upcoming season.
