Brilliant. Does exactly what it says.
Bought the 75kg version and it arrived promptly. Obviously if you weren't aware, the listing is for a flatpacked sandbag only - you have to provide your own sand. Would be unfair to ask postie to lug 100kg down the drive! The price seems quite steep with that in mind but its very competitive with the competitors so who am I to argue. The bag feels of a great quality and is a "bag within a bag" design and has a built in "funnel" and several fastening mechanisms so I don't feel like sand will come out. You can partially fill to start with and then upgrade over time - I started mine with 50kg as that's the weight I feel comfortable taking to the shoulder but I can add up to the 75kg capacity in time. I'd recommend the B&Q (or other retailers') kiln dried paving sand to fill it with. It's a little pricier than the sharp sand/play sand bags but as its already dry it means it's a doddle to pour into the bag and won't dry out and get lighter over time. I filled mine to weight by picking it up and standing on the bathroom scales with it - it's too wide to go on the scales on its own without obscuring the display so you need to lift it onto the scales then subtract your body weight. Training with it is a dream. It's a completely different type of weight that promotes a more full body strength. I like picking it up, getting it onto the knees, then getting it to the shoulder, but there are several workouts you can do with it including squats, and carrying it as far as you can etc. It feels a very high quality and I have no issues dropping it from shoulder height onto my garage's concrete floor, or my driveway's block pavers. No signs of wear etc.

Tough, Strong and will take 50kg
Very happy with the sand bag. Seems very robust and will take 50kg just right. Could squeeze another 1-2kg in but not needed. I've added a pic to make that comment on capacity redundant. Good addition to training. Uploaded a pic 3month on, going strong with no issues. Nice flex to the bag while still being firm. Would happily put it side by side with the Cerberus bag quality wise.

Great product!
Needed to get a new sandbag over 100kg since I had a competition coming up, so I ordered this (125kg) sandbag to get comfortable with it and I finally managed to get it to the shoulder. Been using it each week and so far I'm happy with the material, being strong and reliable, way better then other brands I've used, and considering the price of this was far cheaper, I'm happy with the results. Soon I be getting the 150kg bag.

Great sand bag for strength training!!!
I watched so many U tube videos on sand bag training so I decided to give it a go. And I wanted to develop some functional strength and not traditional weight training. Well I wasn't disappointed. I ordered the 75kg bag. And boy!!! What a great workout. I managed to lift it up to my waist 3 times and do some carrying with it. Anyway the bag itself is well made and quite strong. I filled it up to the brim with sand and it could even be heavier than 75kg!!! After one session in my back yard I feel super strong!!! 💪🏽😂 If you are going to use sand. Get the dry paving sand. This will be easier for you to fill. I used building sand which was a bit damp. But it works just as well but does leave wet patches outside the bag. But I have recently brought a 50kg bag which I will fill up with dryer sand. This bag will be to warm up before I tackle the 75kg. Otherwise this sandbag is a great bag & I strongly recommend you get for training!!! And it's great value for money!!!

Well put together
So 1st of all they come empty just incase you think they don’t , so you need to buy sand I used kiln dried which made filling it up easier , there is like a bag inside that you fill up this has a good Velcro fastening you then took this down and the outer bag has another great Velcro fastening so no leaking sand. The size is good but you probably need to you tube how to shoulder one as there’s a bit of a technique to it.
