Lightweight merino wool mens LS crew top for $59.96 from Mountain Designs
Similar merino wool crews that I found online were upward of $100. Both Summit Gear and GearGuys have a merino LS mens crew on discount at $108. While Summit Gear's SmartWool crew has the exact same fabric weight of 195gsm, GearGear's Icebreaker LS crew is slightly heavier at 200gsm.
Mountain Design still have this crew available in all sizes and it comes in four different colours: black, blue, red and maroon.
You'll need to add an additional $12.95 on top for delivery to any address in Australia, bringing the total to $72.46. Sale ends 4th of August 2013.
