Multipass by Dahlgren

  • We make great pants and shirts and our new sock partner makes great socks! We are proud to offer socks by Dahlgren. Made in the USA with Merino and Alpaca wools these socks excel in cushioning and moisture wicking. Patented DriStride Technology uses independent zones of merino/alpaca and ThermaDri to absorb and remove moisture more effectively, keeping you softer, drier, and blister free wherever you go.

    Crew | Moderate Cushion

    The all-time, year after year bestselling style, the MultiPass will never let you down. With dense, moderate cushion throughout the entire sock, the MultiPass provides soft support without bulk. Whether you're hiking the PCT or across the parking lot to your office, this is a sock that you'll want to wear every day and thanks to its versatility, you can!

    • Moderate cushion throughout sock for greater comfort.
    • Crew length top stands 10.5" tall in men's large.
    • Patented Dri-Stride® System.
    • Alpaca/Merino Wool in Absorption Zones.
    • Therma-Dri™ in Transfer & Evaporation Zones.
  • Fabric Features

    Dahlgen socks use a blend of 70/30 Merino wool and Alpaca in the toe, heel, Wicking Rings™, and Wicking Channels™ of our socks. We use ThermaDri™, which is our proprietary polyester made for softness, durability, and performance, in what we call the "body" of the sock.

    With Dahlgren’s patented Dri-Stride® Technology, your Dahlgrens become a secret weapon against temperature swings, discomfort and even blisters. We want you to focus on your activity, not your feet.

    The solution is to treat the sock as two zones: The zone inside the shoe and the zone outside the shoe.

    Dahlgren’s patented Dri-Stride® Technology

    By absorbing and removing moisture as it is created, feet are warmer in cold temps, cooler in warm temps, and drier and more comfortable everywhere. Dahlgren socks are made using our exclusive, patented Dri-Stride® Moisture Management Technology in every beautiful sock we produce. We use Alpaca & Merino wool in our Absorption Zones and Therma-Dri™ synthetic fiber to transfer and ultimately remove moisture from your shoe. Many claim to remove moisture, but only Dahlgren has Dri-Stride® proven effective technology.

    A regular wash cycle with any non-bleach detergent and a low to medium heat dryer will do the job just fine. Our socks will not shrink and hand washing and/or line drying is not necessary.

    Finer points (optional steps that will enhance and protect performance and appearance):

    • Choosing to use fabric softener is fine and will not cause any harm to the socks, however for maximum absorbency we recommend against fabric softener as that creates a fine wax-y barrier over all of the fibers. In fact, a quarter cup of white vinegar added to the wash cycle can help remove all traces of detergent and really prime the fibers for maximum absorbency.
    • High heat for extended periods ( ie, a long, hot dryer cycle or a "sanitizing" wash setting ) is not recommended as it can harm the natural fibers, causing a stiffening and thickening also known as "felting"--this specifically applies to the merino wool.
    • You can reduce pilling ( the little fiber balls that sometimes accumulate during washer/dryer cycles ) by washing and drying the socks inside out.
    • The only hard and fast rule is never use bleach.

    By following these basic recommendations, you can look forward to comfortable, durable use for a long time to come.
