Marine Layer Hike & Camp

Frequently Asked Questions

• How does Marine Layer’s Airknit fabric perform on day hikes in hot weather?

  Airknit (typically a 60% cotton / 40% recycled polyester blend) is soft, breathable, and wicks moisture better than 100% cotton, making tees like the Signal Peak comfortable on warm hikes. It dries quicker than all-cotton shirts and has some odor resistance and UPF protection, but it isn’t waterproof—pair with a lightweight shell for wet conditions.
• What size should I choose for Marine Layer shirts and hoodies if I want room for layering?

  Marine Layer uses a relaxed, athletic unisex cut (XS–XXL with petite/tall options); if you plan to wear a mid-layer or insulating layer underneath, size up one for additional clearance in the chest and shoulders. For solo wear choose your usual size for the intended relaxed fit, and consult the brand’s chest/waist size chart since drop-shoulder styles can fit looser on women.
• How does the Signal Peak Tee compare to the Reformation Shirt for trail and camp use?

  The Signal Peak Tee is a lightweight, short-sleeve Airknit tee built for high-mobility, hot-weather hiking and quick-dry comfort, while the Reformation Shirt is a button-up designed for sun coverage, breathability, and casual layering around camp. Choose the Signal Peak for higher-output activity and the Reformation for sun protection, light layering, or trail-to-town versatility.
• Are Weekend Shorts from Marine Layer a good choice for multi-day backpacking?

  Weekend Shorts are hybrid, packable shorts suited to day hikes and camp use thanks to their lightweight construction and casual comfort, but they’re not built as rugged, reinforced technical shorts for heavy abrasion or extended thru-hiking. For multi-day backpacking you may prefer shorts with heavier nylon or reinforced panels, stronger water-shedding finishes, and more secure pocketing depending on terrain and carry weight.
• What’s the best way to care for Marine Layer pieces to keep them soft and durable?

  Wash garment-dyed Airknit and cotton-recycled blends in cold water and tumble low or air-dry to preserve softness, color, and recycled polyester performance; avoid bleach and high heat. Turning garments inside out, using gentle detergent, and following the label’s washing instructions helps flatlock seams and UPF properties hold up over many washes.
