Foundations T-Shirt ~ Sage • Aspinwall Mountain Wear

Men’s Foundations Shirt

The perfect foundation for every day in the mountains — and everywhere else.

We set out to build the one t-shirt you’ll reach for again and again. The Foundations Shirt is our elevated everyday essential: a premium lifestyle tee that looks like the high-end blanks billionaires wear, but performs like something made for real life. Soft, versatile, and built to last.

Made from a premium 90% Cotton / 10% Spandex blend, it delivers an ultra-soft hand feel with just the right amount of stretch and recovery. It moves with you whether you’re heading to the gym, packing out an elk, running errands, or dressing it up with jeans. After 10+ washes, this shirt still looks fresh out of the package — no pilling, no shrinking, no fading.

Why it stands out:

• Ultra-soft brushed feel that gets better with every wear

• Excellent stretch & recovery — holds its shape without bagging out

• 1” ribbed neckband — substantial and structured (no cheap, wavy Hanes vibes)

• Clean, versatile silhouette — looks elevated blank or screen-printed with your favorite Aspinwall logos

• Built to last — proven through real-world testing and repeated laundering

Available in four foundational colors: Sage, Ash, Black, and Royal.

This is the shirt we built as the base layer of the Aspinwall wardrobe — the one that quietly does everything right so you don’t have to think about it. Simple. Timeless. Foundational.

Wear it hard. It’ll keep up
