Heavy Merino

"I just got mine. Its definitely heavy for merino but not anything like a heavy weight cotton hoodie. Much like most merino its ment to be layered so its form fitting. I choose the color "moonrock" which online looked almost cream but in person is much more sweatpants grey. The only thing I'm not a fan of is the Ibex logo is on the forearm in bright purple. In my opinion this makes the hoodie look very feminine. Its not really depicted in the online images and I probably would have ordered a different color had i seen that. Overall I'm happy with it and look forward to trying it out this winter."
