Who Should Go Ultralight?
Ideal For:
- Sheep/goat hunters covering 10+ miles daily
- Public land hunters needing stealth mobility

Think Twice If:
- You primarily hunt from fixed stands
- Prefer maximum stability over mobility
- Shoot >70lb draw weights
The Mathews Lift 29.5 proved most resilient in our rain tests – its hydrophobic grip and sealed limb pockets functioned flawlessly after 8 hours in downpours. Pair it with EliteArcher’s “Alpine Tuning Package” to optimize cam lean for high-angle shots.
Remember: Light bows amplify form flaws. Our “Backcountry Archery Fitness Program” (free with purchase) strengthens the rhomboids and rotator cuff muscles critical for steady shots at elevation. At 14,000 ft, even 3lbs feels heavy after 12 hours.
