Royal Robbins Training

Frequently Asked Questions

• What is MPT™ (Mosquito Protection Technology) and when should I choose garments that have it?

  MPT™ is Royal Robbins' proprietary, non-toxic mosquito protection applied to fabric and tested in lab and field settings to reduce biting exposure without conventional insecticides. Choose MPT™-treated pieces like the Desert Pucker or Camino Pucker for river corridors, dusk/dawn hikes, and other bug-prone training where lightweight, protective coverage matters.
• How do the Desert Pucker and Expedition III L/S tops compare for multi-day warm‑weather adventures?

  The Desert Pucker uses TENCEL™ Modal for a cooling, soft hand and quick-drying comfort that excels on hot, high-mileage days, while the Expedition III L/S is made from bluesign®-approved recycled polyester ripstop for superior abrasion resistance and durability in rugged terrain. Pick Desert Pucker when you prioritize next-to-skin comfort and temperature regulation; choose Expedition III for approaches, scrambling, or when pack abrasion is a concern.
• Which Royal Robbins shorts and tops are best for high‑intensity versus low‑intensity training?

  For high-intensity work, opt for quick-drying synthetics like the All‑In Short (100% recycled nylon) and TENCEL™ or recycled-poly tops that shed sweat and dry fast. For lower-intensity or basecamp wear, choose hemp/organic cotton pieces such as the Vacationer Turtleneck (or Kickback-style options) for softness and natural odor resistance, keeping in mind cotton/hemp absorb moisture more than synthetics.
• How should I size Royal Robbins training apparel for layering and unrestricted movement?

  Royal Robbins favors movement-focused, versatile fits—boxy shirts and shorts with non-slip waistbands and interior drawcords—so size for your intended use: take your usual size for a standalone, active fit or go up one for more room to layer. Pay attention to stated inseams (example ranges include ~2.5" for some women’s shorts and ~5" for some men’s) and features like adjustable cuffs and fold-up collars that affect fit and layering.
