Here's the breakdown of the four phases:

Phase 1 is a lightweight first layer that has superior moisture-wicking and clean seams for dry, irritation-free wear. Phase 1 wear is perfect for hot to temperate weather.

Phase 2 is a mid-weight waffle garment that works as a great base layer for temperate to cold climates or as an individual piece in warmer weather.

Phase 3 is super mid-weight and adds four-way stretch and 8% spandex to XGO's acclimate dry polyester to make this heavier garment more flexible. These shirts also have better insulating properties than regular cotton undergarments.

Phase 4 is heavy-weight tech face fleece, a strong layer with four-way stretch and 10% spandex for the ultimate balance of warmth and maneuverability.

XGO base layer gear fits the bill for keeping you dry and comfortable in any situation. Wear one alone or layered to customize for a variety of climates. Our soldiers love XGO and so will you!
