Merino Wool

PASSING THE COMMANDO TEST

In WWI, wool was so important to British soldiers on the front lines that knitting wool sweaters was seen as a patriotic duty. By WWII, wool’s reputation was further solidified. However, members of the SAS were in the field for long stretches of time, wearing rucksacks and carrying other gear, and they were always on the move.

They saw too much failure of their traditional wool sweaters, and they needed something lighter, so they added reinforcements to the shoulders and the elbows. This became the iconic British Commando Sweater, and the inspiration for what we call the “commando test” — to pass muster, merino wool must be reinforced in high stress areas. If it’s not, it simply fails too fast like the traditional wool garments that the SAS rejected.

Reinforced paneling — found on ALL GORUCK Merino Wool products — represents the standard for performance in the merino wool category. This means your merino shirt keeps its structure better over the long haul while you get all the benefits of merino like no stink and perfect temperature regulation no matter the adventure, or the mission.

TESTED AND PROVEN: "I Wore the Same Shirt for 8 Days"

72 hours is just an appetizer for our merino shirts. When we say that this shirt can be worn 24/7, 7 days a week we mean it. We took our Merino Tee out into the real world and wore it 8 days straight, across different countries.

“I Wore it for 8 straight days, without washing it, in six difference cities. The hottest day in the history of London (literally), on scooters all over Berlin including the wall, planes with my kids' rucks (and my kids) all over me. At the North Sea where it was cold AF, so I used it as a base layer. Train stations, bus stations, biking and hiking all over St. Peter-Ording, even at some proper “bizness” meetings in Hamburg, at the second most famous castle in Germany, and in plenty of fine drinking establishments with old and new friends. (Our Merino goes perfectly with a tall Hefeweizen). On the 8th day, we had a 6 hour train ride to Munich with no A/C. Our son Jack stripped his shirt off and fanned himself the whole way. I got to our room and washed my shirt in the shower and prepped it for another 8-Day run, or more”. - Jason McCarthy, Founder, GORUCK
