Wilderness Wear MerinoFusion Duo 300 Men's Long Sleeve Crew Top Review

The Wilderness Wear MerinoFusion Duo 300 Long Sleeve Crew Top was released in 2019 but I missed the opportunity to test it out in winter conditions until just recently when the temperatures started to again drop below 0° Celcius.

At first consideration this top doesn’t sound very different to other tops on the market being a blend of both polypropylene and Australian Merino wool. Where this top is unique is that the garment actually consists of two layers. The inside green layer is polypropylene and the outside is an 18.5 micron Australian Merino wool layer. What this does is provide a supremely comfortable  and soft feel against the skin in addition to providing all the advantages of the wool on the outside. This unique layering system provides high moisture wicking, a garment that dries fast when it gets wet, and minimal odour.

The material weight is 200 gsm and Wilderness Wear recommends this top as a thermal base layer. Given that it sits in the high warmth category of tops provided by this Australian owned, Australian manufacturing company it is suitable for the cooler conditions ranging from mid-late Autumn through to early-mid Spring. Colour-wise there is one option black with a lime green inner. The outer layer while black tends to look almost dark navy due to the inside green layer.

Other features on this top are thumb holes to provide additional warmth to the hands in colder temperatures and the flatlock stitching common to other Wilderness Wear garments. One thing worth mentioning is that because this is a cold weather garment, it isn’t light weight with my double XXL top weighing in at 354 grams which is heavier than my The North Face Thermoball Hoodie lightweight thermal jacket (only just).

Size wise this is the first XXL top I have ever worn given I’m currently the heaviest (at 110 kg) I have ever been. Also as someone who has lifted weights for many years I have a fairly broad chest and this top fits well, as per the company sizing, even with its slim fit but given all of the above, its a firm fit which is how I like my tops. The top and sleeve length are both generous and unlike other brands, there is no corner cutting.

Like most hikers I use a layering system that provides a high degree of versatility over a wide range of temperatures and for me this includes a long sleeved lightweight top as well as a long sleeve heavier weight top. My current go to heavy weight top is the Wilderness Wear MerinoFusion 195 Long Sleeved Zip Neck Top which would be replaced by the Wilderness Wear MerinoFusion Duo 300 Long Sleeve Crew Top. How you decide which one you would use essentially comes down to a personal choice between a high neck zip top or a a crew neck top. Where the Duo wins out is in the supreme comfort provided by the inner polypropylene layer.

We like

  • High quality Australian Merino and polypropylene dual layered fabric
  • Supremely comfortable to wear against your skin
  • Double sewn flat seams prevent chafing and keep this garment comfortable no matter how heavy the pack or how many layers you wear
  • Excellent length in both the body of the garment as well as the sleeves which is great for those of us with a bit of extra height and reach
  • Australian owned, Australian made

We don't like

  • This top is for colder conditions only
  • Single colour choice only
