    Excellent quality, Increased fitness

    Posted by Kyle Denton on 26th Jan 2020

    I love my 40 pound weight vest. This may be a little lame but everyday in the morning and after work I throw it on while I'm doing household chores probably about 30 to 40 minutes total per day. At 1st my shoulders were sore after 10 minutes or so But I feel myself getting stronger as now I can wear it 30-40 minutes at a time without My traps feeling super sore. My body feels lighter and I feel more agile at work. it's increasing my overall fitness. I've had a pectoral strain injury for the past few months and it's almost healed and once it's healed all the way I'm going to incorporate this weight vest in to some body weight training. I Happen to personally use freeletics. Push UPS pull ups, Squats, Etc. But yeah, Just wearing the thing while I'm cooking and doing the dishes and vacuuming and all that junk has increased my muscle and endurance and strength. I may Use it while hiking in preparation for backpacking trips.

    40 lb box vest

    Posted by Unknown on 1st Jun 2019

    I have the 40 lb. box vest. I have a lot more freedom of movement than with my previous vest. I only use 20 lbs right now. As far as for the fit of the vest, I'm 6'4" and the bottom if the vest is about 1 to 2 inches above my belly button which is fine for me.

    Great Product!

    I was looking for a comfortable, well-made weight vest I could use for workouts and hiking. I bought this one after trying out quite a few.

    I’ve been using this one almost daily since it arrived and am very pleased with my purchase.

    Box Vest

    Posted by Tutlo on 17th Apr 2019

    The Box Vest stays contour to your body, very snugged (tight). Goes down right underneath the pecs so you have plenty momentum. I can do all workouts with ease, and not have to worry about shoulder pads breaking or the beads pulling apart since the beads are in a sealed in metal material. Feels nice on your body when very hot out and doesn’t make it feel more dense with it on. Mine is just a basic but you can add additional weights or mod your vest with other things to your liking. Comes in many different colors too. Packaging was secured and shipping was quick. Is expensive but worth it for heavy resistance and building strength and core. Doesn’t move around when running which is great too. 10/10!

    Great for law enforcement officers.

    Posted by Unknown on 25th Sep 2017

    Over 30 years of law enforcement. I was using an old sand-filled weight vest for my calisthenics workout (MARSOC short card). I finally upgraded to the Box 40 pound vest. Great piece of equipment. It fits well, the weight is evenly distributed and I can perform my workout with no issues. Have done some sprints with it on and although it bounces a little it's not a problem. I've found the best way for me to tighten the vest is to lie on my back and then pull and tighten the side straps. We officers wear about 10 to 15 extra pounds of gear on our upper bodies every day, this vest helps make that load feel lighter. If you are in law enforcement I strongly encourage you to make fitness a career long endeavor. This vest will help you chase down criminals half your age. It's a career investment that will last you your career.

    Awesome Fit

    Posted by Unknown on 5th Jun 2017

    As a small-ish female I was worried this vest might be a little too broad for me and I didn't love the cut for the female vests. Completed Murph on Memorial Day with this vest and it was perfect!
