Frequently Asked Questions
Are weight vests safe for trail running in hot weather?
Yes, if chosen and used carefully. Pick a breathable, well-fitting vest and start with lighter loads to assess heat and effort. Stay hydrated, pay attention to overheating signs, and avoid very heavy loads on technical trails where balance matters more than extra resistance.
How much weight should I add for trail runs and hikes?
Begin conservatively — 5–10% of body weight or an additional 5–15 lbs depending on fitness and experience. Increase gradually in small increments using removable packets to avoid joint stress and preserve form on uneven terrain.
How do I prevent chafing, smells, and vest bounce?
Choose a vest with padded/wide straps, breathable materials, and a secure waist system. Wash or air out new vests to reduce factory smells, use anti-chafe balm on hotspots, and tighten straps or adjust packet placement to minimize bounce.
