Gymshark Geo Seamless T-Shirt vs Smartwool Active Ultralite Short Sleeve

Buy the Gymshark Geo Seamless for gym sessions and hot-weather training where you want a close, stretchy fit and a sporty look. Buy the Smartwool Active Ultralite for hiking, travel and all-day wear, where merino's odor resistance and temperature regulation matter more than a sculpted fit. The Gymshark is a synthetic performance tee with a slim cut and jacquard camo; the Smartwool is a merino-Tencel blend with a softer hand and better odor control. Owners of seamless Gymshark tees praise the stretch and breathability but note the slim fit runs close and the synthetic fabric holds odor faster than wool.

• Choose the Gymshark Geo Seamless if you train hard in the gym, want a slim raglan fit that moves with you, and prefer a synthetic seamless tee you can wash and wear fast.
• Choose the Smartwool Active Ultralite if you hike, travel or wear one tee for days and want merino's odor resistance, temperature regulation and a softer feel against the skin.
