Arc'teryx Merino Wool Clothing

Waterproof vs. water-resistant

• A waterproof jacket keeps out hard, driving rain
• A water-resistant jacket can handle light rain for a brief time and is more breathable

Windproof vs. wind-resistant

• Any waterproof jacket is also windproof to shield you in stormy weather
• A wind-resistant jacket will offer much lighter protection

Hard shell vs. soft shell

Like a waterproof and windproof rain jacket, a hard shell will offer the most protection, but less breathability than a soft shell.

Do you need insulation?
For very cold rainy weather, consider an insulated shell, which will have down or synthetic fill for warmth while being waterproof and windproof.

Where do you plan to run?

• Light trail: Best for well-groomed trails
• Rugged trail: Work on a wide variety of terrain, including technical trails
• Off trail: A more aggressive design protects you on rocky, extremely variable terrain

Cushion comes down to “feel” vs. “float”

• Minimal and barefoot cushioning: little to no padding, more ground feel
• Moderate cushioning: more traditional ride
• Maximum cushioning: softest, bounciest ride

Check the heel-to-toe drop

Barefoot and minimalist shoes are very flat with 0-4 mm drop. Moderate and maximalist shoes have higher drop. Choose what you're used to.

Consider the fit

Don't assume you know your size—go to your local REI or running-shoe store to get a fit assessment. Happy running!
