The tank that solves the backpack problem.

Here's the issue nobody talks about: shoulder straps. Backpack straps, chest rigs, bino harnesses - they all sit exactly where your shirt seams are. Miles of friction. Constant chafing. Ruined shirts by the end of the season.

The Tech Tank eliminates all of it. Cut-off design means nothing for straps to catch or rub. Wider shoulder straps distribute weight without digging in. You can carry heavy loads all day without your shirt working against you.

Built with DUAL SURFACE™ UL Precision Blended Wool at 3.5 oz - one of the lightest base layers we make. The inner surface actively wicks sweat away from your skin. The outer surface provides UV protection and natural odor resistance. You stay cool when it's hot, dry when you're working hard, and you can wear it for days without stinking up your pack.

Why this works:

• Ultra-lightweight (3.5 oz) - disappears under your kit
• Cut-off design eliminates backpack strap chafing and seam friction
• Wide shoulder straps for load-bearing without digging in
• Natural odor resistance through multi-day use
• Built-in UV protection for exposed skin
• Exceptional wicking and breathability for high-output efforts
• Dries fast when you need it ready for day two

Summer base layer for hot approaches and long carries. Foundational layer in winter under your Tech Tee or River Run Hoodie when you're generating serious heat. Any time you're wearing a pack, binos, or chest rig and need your base layer to get out of the way.

This isn't a gym tank. It's a purpose-built technical piece for people who actually carry weight.
