Overview
The RUNmax RM40_NP is a 40 pound weight vest made of nylon and sold in this version without shoulder pads, aimed at runners and strength trainees who want to add fixed resistance to bodyweight work.
RUNmax lists this vest for cross training, strength training and general workout use, and at 11,900 reviews and a 4.6 rating it has a long track record with buyers. The catch with this particular version is the missing shoulder padding, so comfort during long runs or high-rep circuits will come down to fit and how the straps sit on bare shoulders.
- 40 pound weight, sold without shoulder pads
- Nylon construction
- Black colorway
- Listed for cross training, strength training and workout use
Who it's for
Suits lifters and runners who already know they want a 40 lb add-on load and are comfortable adjusting straps for fit. Less suited to anyone who wants cushioned shoulder straps included in the box.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fixed 40 lb load for training
- Nylon build for repeated wear
- Long review history with a 4.6 rating
- No shoulder pads included in this version
- Weight is fixed, not adjustable
Performance notes
At 40 lbs the vest adds a fixed, non-adjustable load, so the weight itself does not change once loaded. Nylon construction handles the abrasion of repeated wear, and without shoulder pads the strap pressure sits directly on the shoulders, which matters more the longer or more intense the session.
