The details
About the Smartwool Classic Base Layer Long Sleeve
Lightweight merino for every season.
The Men's Smartwool Classic All-Season Merino Base Layer Crew is a lightweight long sleeve layer made to wear on its own or under a shell. It's a year-round piece for cool morning runs, winter layering and everything in between.
Smartwool's 150 g/m2 merino jersey wraps a recycled nylon core while keeping merino wool next to your skin. Merino naturally helps manage moisture, resist odor and regulate body temperature, and flatlock seams help cut down on chafing.
Key Features:
- 88% merino wool, 12% recycled nylon
- Lightweight 150 g/m2 merino jersey
- Merino next to skin for moisture management and odor resistance
- Helps regulate body temperature
- Flatlock seams with offset shoulder and side seams to reduce chafing
- Close, next-to-skin fit made for layering
Ideal For:
Runners who want one merino layer they can wear from fall through spring.
Why We Love It:
Soft, odor-resistant merino you can layer all year.

Questions before you buy
Can I pick it up in store?
Yes, where it's available. Check pickup availability for your size above, then choose local pickup at checkout. We'll email you when your order is ready.
How fast do online orders ship?
Shipping is free on US orders of $75 or more, and $10 below that. Orders are processed within 2 to 3 business days and are not shipped on weekends or holidays. You'll get a tracking number by email as soon as your order ships.
What is your return policy?
Return unworn items in their original packaging within 30 days of delivery, or within 60 days if you're a Coastal Run Rewards member. Return shipping is free. All sale items, and anything bought below its original price, are final sale.
I'm not sure what size to get. Can you help?
Yes. Stop into either store for a fitting, or send us a note and our fit team will help with sizing and a few shoes to try.
Do you carry wide sizes, and can I bring my orthotics?
Many of our shoes come in wide versions, and some have a roomier toe box by design. Bring your orthotics or insoles to a fitting so we can make sure they work with your new shoes.
How do Coastal Run Rewards work?
You earn 1 point for every $1 you spend, in store and online, and can redeem points for money off future purchases. Members also get 60 days, instead of 30, to return unworn, full-price items.
