Critter Birthday Suit: Rugged Performance for the Outdoors
When you donβt want anything to freeze and fall off: The Critter Birthday Suit combines rugged, classic styling with modern, high-performance fabric technology. Built for demanding work or extended outdoor stays, this full-coverage suit delivers comprehensive protection and comfort without compromising mobility.
Constructed using a durable Polartec® fabricβsuch as Alpha Direct for high-output activities, or ThermalPro for exceptional warmthβthe suit creates a thermal barrier that provides a superior warmth-to-weight ratio. Its sleeveless design ensures optimal flexibility with layering, keeping your core and legs consistently warm.
Despite its insulating power, the fabrics remain highly breathable and moisture-wicking, preventing overheating and the clammy feeling that comes from trapped sweat. Featuring two front pockets and a stand-up collar, the Birthday Suit is designed to withstand anything winter can throw at you.
Inspired, designed, and crafted with pride in Crested Butte, Colorado.
