Overview
The WV45 is a nylon weight vest from HANZO carrying a fixed 45 lb (20 kg) load, sized for adding resistance to bodyweight movements like walking, hiking, or calisthenics circuits.
Unlike adjustable vests that let you swap plates in and out, this one ships at a set 45 lbs, so what you buy is what you wear. That makes it straightforward if you already know the load you want, but it removes the option to work up gradually or dial the weight back on lighter days.
- 45 lb / 20 kg fixed weight
- Nylon shell material
- Black colorway
- Built for weighted workout training
Who it's for
Suits lifters and runners who want a fixed heavy load for rucking, weighted stair climbs, or calisthenics and don't need to change the weight session to session. Not a fit for beginners easing into weighted training or anyone who wants to progress the load over time.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fixed 45 lb (20 kg) load in one vest
- Suited to weighted cardio and calisthenics
- Weight is fixed, no way to reduce or add load
- 45 lbs is a heavy starting point for new users
Performance notes
The vest's load comes from its fixed 45 lb fill rather than removable weights, so resistance stays constant across weighted walks, stair work, or bodyweight circuits. The nylon shell is the wearable structure rather than a padded harness system, so comfort over long sessions will depend on fit more than the weight itself.
