Since 1992 Longworth Industries has manufactured the finest technical base layers for outdoor enthusiasts who value performance and comfort. Designed and manufactured exclusively in the United States, Longworth produces three distinct labels:

The PolarMAX brand has proven itself equal to the task of world-class climbers, skiers, snowboarders as well as Iditarod sled racers in the proving ground that is Alaska's rugged wilderness. PolarMAX also provides the United States Army, Marine Corp and Air Force with government tasked moisture management layers for elite units, as well as for Secret Service agents.

The PolarMAX Sportsman's Collection is rapidly becoming the brand of choice for serious hunters and anglers who seek to increase their time/comfort ratio in a variety of climatic conditions.

Longworth's newest brand, XGO combines the legendary PolarMAX and PolarMAX Sportsman's Collection technologies with innovative, sportswear-inspired designs for the outdoor enthusiast who seeks the ultimate in protection, performance, comfort and style. XGO also produces XGO Tactical, a line specifically designed for law enforcement/military personnel to use in comfortable conjunction with body armor or as elite moisture mitigating (warm weather), or wicking/insulating (cold weather) sub layers.

The Sun Protection Center is proud to offer the Phase 3 line of XGO apparel.

The Collection:

Phase 3 (7.5 oz./sq. yd.)

The quintessential multi-purpose/multi-season performance garment; the fit is contoured without feeling restrictive. The term "comfortable compression" has been coined to describe the Phase 3 collection.  This fabric flat out stretches and conforms to movement better than anything else out there. 

Phase 3 garments are constructed with 90% acclimate dry polyester/10% spandex and protected with Scent Prevent anti-microbial. All models feature "off the shoulder" rolled seams and flat seaming to eliminate the grind from load bearing anatomy. Most men's and uni-fit models (long and short sleeve) feature the new engineered O.D. green gusset with additional infused silver anti-microbial protection; Women's models have the same self-fabric gusset design. All Men's and Uni-fit tops have a 2 inch longer body length for performance in high energy activities. Phase 3 garments meet all U.S. Military wicking and retention requirements of 90% after 50 washings. 

The Technology:

Acclimate® Dry fabric rapidly pulls or "wicks" moisture away from the skin to the fabric’s outer surface for quick evaporation, which means you stay drier, warmer and more comfortable. XGO™ pioneered the development of an anti-odor, anti-microbial to meet the demands of the U.S. Military. Scent Prevent® technology stops odor before it starts by killing the bacteria that causes odor.
