Quality socks are the foundation of every adventure. The lifetime warranty provides valuable feedback from users and serves as a driving force for continuous improvement, supporting Darn Tough's mission: **'We design and manufacture the most comfortable, durable, and best-fitting socks.'** **It doesn't matter where you bought the socks** – you can make a claim at the distributor for the Czech market, abroad, and at brick-and-mortar stores of Darn Tough sock retailers (you don't even need a receipt). You can find all the details about the warranty and the exchange process on [this page](/darn-tough-lifetime-guarantee). ## How to take care of socks Merino socks don’t need to be washed after every wear. Merino wool is naturally antibacterial and resistant to odors. In fact, washing them less frequently extends their durability. Therefore, you can wash the socks after a few days of wear or even after a month — it’s all about your personal preferences. Before washing, **turn the socks inside out**. Wash in the washing machine on a **gentle cycle** or in warm water. If your washing machine has a **wool cycle**, you can use this setting. If you’re washing the socks while trekking in the wild, we recommend [multi-purpose cleaner Sea To Summit](/p/sea-to-summit-wilderness-wash-100-ml), which is gentle on both the environment and your socks and skin. **Do not use bleach or fabric softeners.** Leave the socks to dry in the dryer on a low temperature or ideally air dry them. **What to avoid**: High heat and aggressive chemicals can damage the properties of merino wool fibers. To ensure your socks last as long as possible, keep these 4 rules in mind: - Do not clean chemically. - Do not use bleach. - Do not use fabric softener. - Do not iron. ## Specs - Color: Skyracer Blue, Skyracer Gray, Black - Clothing size: L, M, XL - Sock thickness: ultra-lightweight - Sock height: quarter socks - Sex: Men - Material: Nylon, Merino wool, Elastane - Material composition: 46 % nylon, 4 % elastane, 50 % merino wool - Weight: 36 g - Woocommerce product id: 105197 - Brand: Darn Tough ## Variants - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Blue, XL · SKU DT1040SBXL · EAN 642249235364 · €26.40 · Out of stock · Skyracer Blue, XL - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Blue, L · SKU DT1040SBL · EAN 642249235357 · €26.40 · Out of stock · Skyracer Blue, L - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Gray, XL · SKU DT1040SGXL · EAN 642249235333 · €26.40 · In stock · Skyracer Gray, XL - Darn Tough Run 1/4 Ultra-Lightweight pánské - Large, Black · SKU DT1040BL · EAN 642249178692 · €26.40 · In stock · Black, L - Darn Tough Run 1/4 Ultra-Lightweight pánské - Medium, Black · SKU DT1040BM · EAN 642249178708 · €26.40 · Out of stock · Black, M - Darn Tough Run 1/4 Ultra-Lightweight pánské - Xlarge, Black · SKU DT1040BXL · EAN 642249178715 · €26.40 · In stock · Black, XL - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Blue, M · SKU DT1040SBM · EAN 642249235340 · €26.40 · In stock · Skyracer Blue, M - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Gray, M · SKU DT1040SGM · EAN 642249235319 · €26.40 · Out of stock · Skyracer Gray, M - Darn Tough Run 1/4 Ultra-Lightweight pánské - Skyracer Gray, L · SKU DT1040SGL · EAN 642249235326 · €26.40 · In stock · Skyracer Gray, L ## Related - [Darn Tough Women's Run 1/4 Ultra-Lightweight](/p/darn-tough-run-1-4-ultra-lightweight-womens.md) - [DexShell Heathered Rib-Knit Beanie](/p/dexshell-heathered-rib-knit-beanie.md) - [Darn Tough Men's Light Hiker No Show Lightweight](/p/darn-tough-light-hiker-no-show-lightweight-mens.md) - [Montane Protium Glove](/p/montane-protium-glove.md) - [Darn Tough Men's PCT Micro Crew Lightweight](/p/darn-tough-pct-micro-crew-lightweight-mens.md) - [Sea To Summit Ultra-Sil Dry Bag](/p/sea-to-summit-ultra-sil-dry-bag.md) - [Darn Tough Men's Number 2 Micro Crew Midweight](/p/darn-tough-number-2-micro-crew-midweight-mens.md) - [Sea To Summit Lightweight View Dry Bag](/p/sea-to-summit-lightweight-view-dry-bag.md) ## Shipping and returns - [Shipping and payment](/shipping-payment) - [Returns](/return-order) ## Images - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/bedd43e7a7ddf088fa9e96e5c4cca21b-01KWHVKN0CJNFMHKA03GFYWVFZ.jpg) - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/1040_SkyracerGray-Men-01M07GPCWRNCYJTFN2BTX519GT.jpg) - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/02_1040_SkyracerGray_LS-01M07GPCWWS1MM0HVB7NT8VCGX.webp) - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/1040_Black_2-01M07HVSNYAE415BF680P1DAZ7.jpg) - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/DT1040-Skyracer-Blue-01-01M07HVT04FS6ECTRA6S0MDTBY.jpg) - ![Darn Tough Men's Run 1/4 Ultra-Lightweight](https://media.gramino.com/medusa/966c22f0bdb93ff5b20ea580de0f9035-01KWHVKN07KE5ZDGMB1CB6K3MM.jpg) ## Identifiers - SKU: DT1040SGXL - EAN: 642249235333 - Handle: darn-tough-run-1-4-ultra-lightweight-mens - Brand: Darn Tough This product is also available as [HTML](/p/darn-tough-run-1-4-ultra-lightweight-mens).
