Men&';s Burton Reserve 2L 3-In-1 Pants 2027 The Men&';s Burton Reserve 2L 3-In-1 Pants deliver serious versatility with a 20K/20K shell and removable insulated shorts that let you adapt your setup as conditions change. The DRYRIDE(TM) 2-layer recycled polyester shell provides waterproof, breathable protection with fully taped seams, while the removable shorts use 100g ThermacoreECO insulation to add warmth through your core on cold days without blocking the thigh vents. Wear the complete system when temperatures drop, remove the shorts and run the shell as things warm up, or wear the insulated shorts on their own thanks to a dedicated snap closure, fly, and adjustable waist. Removable suspenders, mesh-lined thigh vents, and a full pocket setup round out a versatile pant built to cover more of the season with one setup.
