Answer:
The ULTRA 5000 series comes in four internal harness variants: plastic slip fit (5000L), plastic ratchet fit (5000 LRX), textile slip fit (5001 L), and textile ratchet fit (5001 LRX).
Udyogi manufactures the ULTRA 5000 platform in four primary model variants based on harness material and adjustment mechanism:
- 5000L: 6-point plastic cradle with manual slip-fit adjustment (total weight: 370 g).
- 5000 LRX: 6-point plastic cradle with wheel ratchet-fit adjustment (total weight: 378 g).
- 5001 L: 6-point breathable textile cradle with manual slip-fit adjustment (total weight: 370 g).
- 5001 LRX: 6-point breathable textile cradle with wheel ratchet-fit adjustment (total weight: 378 g).
All variants share the identical HDPE triple-rib shell architecture, 40 mm peak, 15 mm accessory slots, and 530 mm–600 mm headband sizing range.
