Description
The Lightweight Baselayer is where every serious hunt begins. It’s the layer closest to your skin, and it sets the tone for how you move, how you manage moisture, and how well you stay concealed. Designed with a high-performance synthetic and merino wool blend, it keeps you dry, suppresses scent, and delivers comfort that doesn’t fade over time. Whether worn alone in mild conditions or stacked beneath your late-season system, this is your foundation for full-season focus.
Built For The Bowhunter
- Temperature-Regulating Foundation: Lightweight 150GSM insulation balances warmth and breathability to support long sits or active hunts without overheating.
- Moisture Management You Can Count On: Wicks sweat off your body and dries quickly to reduce chill and discomfort when the pace changes.
- Zero Bulk, Maximum Performance: Low-profile cut layers seamlessly under other gear—adding warmth without limiting movement or introducing noise.
- Silent Under Pressure: Soft, smooth, and soundless against your outerwear so you can stay quiet in motion, draw, or stillness.
