Review: La sacca è ben fatta e sembra proprio robusta (anche se il produttore dichiara che non è adatta allo “slamming” cioè ad essere sbattuta con forza a terra). Le cuciture sono solide ed il velcro di chiusura molto forte. Io ci ho messo 40 kg di ghiaietto e non c’è nessuna fuoriuscita di materiale. La chiusura si effettua con una cerniere robusta coperta da una protezione fermata da velcro. Sotto la cerniera c’è la bocca del sacco che accoglie il peso e questa bocca di sacco si chiude con un velcro molto forte che poi si ripiega su se stesso e si fissa con un’altra stirscia di velcro così che non si srotoli, poi vi si chiude la cerniera sopra e la protezione. Finora nessun segno di usura.
Review: 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.

Habe mir zunächst mal den 50 Kilo Sack gekauft um Sandsacktraining (Heben, Stemmen, Tragen) in mein Training zu integrieren. Ich schiele schon auf den 75 Kilo Sack, aber der 50er haut auch schon gut rein. Die Qualität ist bisher Top, der Sack ist gut verarbeitet, leicht zu befüllen und macht alles bisher klaglos mit. Inklusive Fallen lassen auf verschiedene Untergründe aus knapp 2 Meter Höhe. Ob er zum Werfen taugt kann ich nicht beurteilen, solle aber theoretisch auch gehen, wenn man diese Gewichte den Werfen kann und mag. Der Stoff füllt sich stabil und wertig an. Er hat auch Drops outdoor auf Pflastersteine gut vertragen, ob es auf Dauer empfehlenswert ist kann ich nicht sagen. Nutze ihn hauptsächlich im Indoor Gym auf Bodenmatten. Zum Befüllen stülpt man eine Innensack aus, der mit einem recht stabil wirkenden Reißverschluss verschlossen wird, und dann noch mit einer Klettlasche geschützt wird. Für mich ein Topsystem. Ich habe den Sack mit feinem Kieselschotter vom Baumarkt gefüllt, der ist günstig und kommt praktischerweise in 25 kg Plastiksäcken, so spart man sich das abwiegen. Der Vorteil gegenüber feinem Sand ist, dass er sich im Sandsack mehr wie eine lockere Masse mit dem Sack bewegt/formt. Das finde ich angenehmer beim Interagieren damit. Nehmen kann man am Ende aber was man mag, die große Öffnung macht das Befüllen einfach.
