Rank #2 in Best Training Sandbags 2026: 10 Ranked, Filled or Unfilled
Yes4All Unfilled Weight Bag, 20-90 kg
Price and rating as shown on Amazon when we collected them. Both change.
The Yes4All Weight Bag takes second place in this guide, and it is the clearest example of the pattern running through it: what you pay for is the shell, not the weight. £36.14 buys an unfilled bag whose own product dimensions put the shipped item at 1.2 kg. The title offers 20 kg, 30 kg, 50 kg and 80 kg versions, while the bullet list underneath describes four sizes — S at 2–11 kg, M at 11–34 kg, L at 34–56 kg and XL at 56–90 kg.
That 80 kg against 90 kg is a ten-kilo disagreement inside one listing, between the headline and the small print. The size and colour fields then give a third version of the middle bag — "M (0 - 34KG)" against "K. Camouflage - (11kg - 34kg)" — and the included components line says one small plus one big inner bag where the bullet list says two medium ones. Everything on this page is taken from the Amazon listing, not from a bag we filled and carried ourselves.
How those 3,133 ratings break down
An average hides its own shape. This is the spread behind the 4.3 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Great bit 'o kit, I read reviews which stated that the inner bags were hard to fit inside once filled, So I left the inner bags inside the main bag and my wife held them open whilst I poured in bags of sand. The more time and care taken results in less spillage, I got 28 kilos of sand in of which I am happy, It's a great work out climbing the stairs and walking round the garden.”
Verified purchase“Been using this for over a year now and it's been given a beating and it's held up very well, good quality and very robust.”

Questions people ask
Does the Yes4All weight bag arrive filled?
No. The listing says it is sold unfilled, and the product dimensions put the shipped item at 1.2 kg — the sand is bought separately.
How much sand does the size M bag take?
The bullet list gives M as 2 medium inner bags covering 11–34 kg. The size field says "M (0 - 34KG)" and the colour field says "(11kg - 34kg)" for the same bag, so the listing starts M at two different weights.
What is the heaviest Yes4All bag in this listing?
The title lists options up to 80 kg, but the bullet list describes the XL as 4 big inner bags covering 56–90 kg — a 10 kg gap between the two.
How many inner bags come with the size M?
The bullet list says M has 2 medium inner bags; the included components field says 1 external bag with 1 small + 1 big inner bag.
What is the Yes4All sandbag made of?
1000 Denier (1000D) coated CORDURA® nylon, with inner filler bags in water-resistant Cordura fabric and double hook and loop closure strips to prevent sand leakage.
What can the Yes4All bag be used for?
The listing names strength and cardiovascular training, calisthenics, running, rucking, lunges and grip work, and describes it as suitable for beginners.
