Gray Hiking & Camping Clothing & Accessories

Begin with a moisture-managing base layer like SmartWool's 150-weight merino for all-day breathability. Add a fleece mid-layer for insulation and a waterproof hardshell when storms or wind are expected.

Zip-off trousers with detachable legs are perfect for transitional days because you can convert between full-length and knee-length styles without carrying extra pants. Keep full-length trekking trousers for cool, buggy sections and switch to shorts or zip-offs when the sun heats up.

For active hiking pick a lighter-weight merino or polyester base to move moisture quickly—SmartWool's 150-weight is a common all-day choice. Heavier weights work better when you'll be mostly stationary or facing very cold conditions for added insulation.

Softshells or a gilet give the best balance of ventilation and wind resistance for cool, blustery day hikes. Fleece like the REI Co-op Trailmade provides warmth and packs small, but pair it with a windproof layer since fleece alone doesn't block wind.

Pick underwear made from merino or polyester blends with flatseam construction and a snug elastic waistband to prevent chafing and slippage. Anti-microbial treatments and quick-dry fabrics help reduce odor between washes, and you should avoid cotton which holds moisture.
