Midweight - Sentinel Men's S/S Crew 100% Merino Wool

Midweight Warmth with Short-Sleeve Versatility: The Sentinel Men’s Merino Wool Crew

Built for high-output days when you want core warmth without full-sleeve coverage, the Sentinel Men’s Short Sleeve Crew brings an uncommon level of versatility to a technical merino layer. Made from 100% Australian merino wool in a substantial midweight knit, it works comfortably beneath additional layers on cold starts or on its own as temperatures rise. From early trail miles to the summit and back again, it delivers natural temperature regulation, moisture management, and odor resistance for long days outside.

Thoughtful Design & Materials

100% Merino Wool Construction: Made entirely from Australian merino wool for natural warmth, breathability, moisture management, and next-to-skin comfort.

Midweight Interlock Knit: The 245 g/m² fabric provides meaningful insulation through the core while maintaining the freedom and versatility of a short-sleeve design.

Fine 18.5-Micron Fibers: Soft merino fibers create a comfortable feel against the skin, making the Sentinel well suited to extended wear.

Short-Sleeve Performance Design: Combines the insulation of a midweight technical layer with increased arm mobility and less bulk beneath jackets and outer layers.

Performance You Can Rely On

Natural Temperature Regulation: Merino wool helps retain warmth when conditions are cold while remaining breathable as temperatures or activity levels increase.

Moisture Management: The natural fiber structure absorbs moisture from the skin and releases it into the air, helping maintain comfort during strenuous activity.

Natural Odor Resistance: Merino naturally resists odor buildup, an advantage during long trail days, multi-day trips, and extended wear between washes.

UPF 50+ Protection: High-level UV protection adds useful coverage when the Sentinel transitions from a base layer to a standalone shirt.

Built for Movement & Layering

Versatile Layering: Wear it beneath long sleeves, fleece, or outerwear during cold mornings, then use it alone as the day warms.

Flatlock Seams: Smooth seam construction helps reduce friction and chafing during hiking, running, biking, and other active pursuits.

Tagless Comfort: A tagless neckline eliminates the irritation of traditional neck labels during extended wear.

Regular Fit: Provides enough room for comfortable movement without creating unnecessary bulk beneath additional layers.
