The Maker
Hirsch Natur
Hirsch Natur is a German legwear specialist making socks, tights, and leggings from natural fibers. The brand works with cotton, wool, and natural fiber blends rather than synthetics, and every pair is made in Germany with close attention to fiber sourcing. For families and adults who want natural fiber socks without polyester or nylon, Hirsch Natur is one of the established names in European natural legwear.
When to Wear
Lightweight Socks for Warm Seasons and Everyday Wear
These socks are made for warm weather, mild climates, and days when breathability matters more than insulation. The high organic cotton content keeps feet feeling cool and dry, while the 15% organic wool adds stretch and helps the sock hold its shape. Wear them from spring through fall, around the house with slippers, or year-round if you find all-wool socks too warm. Looking for thin wool socks for summer? This cotton-majority blend is the lighter option in the Hirsch Natur range.

Organic wool
Made in Germany
GOTS (Global Organic Textile Standard) is the leading worldwide standard for organic textiles. It covers organic fiber farming and the full processing chain, including spinning, dyeing, and finishing, with environmental and social criteria at every stage. The wool content is what separates these from a plain cotton sock: it gives the knit natural spring so the socks stay snug at the cuff and heel instead of stretching out.

Be Informed
What You Should Know
Who These Work Best For
Men and women who want a lightweight, breathable natural fiber sock for warm weather or everyday wear. People who find all-wool socks too warm. Anyone avoiding synthetic socks who still wants the stretch and shape retention that wool provides.
Caring for the Sole
Like all Hirsch Natur socks, these are made from untreated natural fibers with no synthetic sole reinforcement. That keeps them soft, but it also means friction can thin the sole fibers over time. To extend their life significantly, wear them with slippers or house shoes indoors. This simple step protects the sole from everyday friction on hardwood, tile, or carpet and keeps the socks looking and feeling like new.
Care Commitment
Because these socks contain wool, hand washing is the recommended method. It takes only a few minutes and protects both the wool and the fit. A machine wool or delicate cycle in cold water can be used, but the wrong settings will cause shrinkage and felting.
Care & Longevity
How to Wash Cotton & Wool Blend Socks
Hand wash recommended. Cold water, wool wash detergent, lay flat to dry.
Hand wash preferred
Cold water
Wool wash detergent
Lay flat to dry
No tumble drying
No fabric softener
Hand wash in cold water with a wool-specific detergent such as Eucalan or Sonett wool wash. Swirl gently, avoid rubbing or twisting, and press the water out instead of wringing. Reshape and lay flat to air dry away from direct heat. Skip fabric softener: it coats the fibers and reduces breathability.
If you prefer to machine wash, use only the wool or delicate cycle with cold water, a low spin, and wool wash detergent. Never use a regular or hot cycle, and never tumble dry. Warm water, agitation, and dryer heat cause wool to felt and shrink.
Please Note
Shrinkage is caused by improper washing routines, such as warm water, regular machine cycles, or tumble drying. EcoAble is not responsible for shrinkage resulting from improper care.
Questions
Frequently Asked Questions
How should I wash Hirsch Natur cotton and wool socks?
Hand washing is recommended. Use cold water and a wool wash detergent, press the water out gently, and lay flat to dry. If you machine wash, use only the wool or delicate cycle with cold water and a low spin, and never tumble dry. Improper washing causes shrinkage, and EcoAble is not responsible for shrinkage resulting from improper care.
Are these socks good for warm weather?
Yes. With 85% organic cotton, this is the lighter, more breathable blend in the Hirsch Natur range. It suits spring through fall, mild climates, and anyone who finds all-wool socks too warm.
Why should I wear slippers over these socks indoors?
These socks have no synthetic sole reinforcement, which keeps them soft and natural. Friction on hardwood, tile, or carpet can thin the sole fibers over time. Wearing slippers or house shoes over them indoors protects the sole and extends the life of the socks significantly.
Will these socks itch if I'm sensitive to wool?
With only 15% wool and 85% organic cotton, this is the gentlest option for people who are cautious about wool. Many people who find all-wool socks scratchy are comfortable in this blend. If you have reacted strongly to wool before, try the socks for a short period first and see how your skin responds.
What is the difference between this and the Hirsch Natur 85% wool socks?
The 85% wool / 15% cotton version is warmer and temperature-regulating, suited to cool and cold weather. This 85% cotton / 15% wool version is lighter and more breathable, suited to warm weather and everyday wear.
Why should I avoid fabric softener?
Fabric softener leaves a coating on cotton and wool fibers that reduces breathability and can trap moisture. Wool wash detergent cleans gently without the coating.
How do I choose the right size?
Stand barefoot on paper, mark your heel and longest toe, and measure the distance in inches. Match it to the Heel to Toe column in the size chart. If you are between sizes, choose the larger size.
