Yes4All (イエスフォーオール) ワークアウト用サンドバッグ 充填なし 調節可能なサンドバッグ ウェイトトレーニング用 ハンドル付き 複数の色とサイズ 5~200ポンド

Great bags for adding sand and working out. Very durable and perform as advertised. Highly recommend.

Absolutely a scam, need to fill up with own sand. That being said, the bag quality is top-notch.

I got a solid 2 years of fairly heavy use out of this bag until the liner bags on the inside started to come apart. I sewed the bags back up, which didn’t last long. The reason this product is getting 5 stars from me is for the customer service. I emailed Yes4All and was contacted promptly about having the bags replaced. Yes4All shipped me two new liner bags, free of charge. Very impressed with their communication and customer service! I would also note the actual bag its self had held up incredibly well. No issues with any stitching or tears at all. I have mine filled with 75 pounds of sand and it’s a perfect snug fit… The liner bags stay perfectly in place and don’t get lopsided.

J’ai acheté ce produit pour l’entraînement. C’est arrivé très vite. Le tissus de la poche principale est très épais et solide. Il y a plusieurs poignées comme sur les photos ce qui permet de faire pleins d’exercices différents. Le paquet comprend aussi deux poches prévu pour mettre le sable de la quantité désirée. Les deux poches sont aussi fait d’un tissus très solide. J’adore et je recommande fortement.

Seems good so far. Material seems of tough quality. The only issue i have so far is the stitching, particularly on the inner bags that hold the material. The velcro is so strong that when putting them apart, it separates some of the stitching. It's not enough to ruin its purpose, it still holds pretty well. I'm just afraid after several uses, the whole thing will eventually come apart. Also, i chose not to use sand due to other reviews saying that sand seeps through the seams and gets all over the place. I chose to buy a bag of gravel to fill the inner bags with. The bigger material helps keep the weight contained within the bags. I will update if anything changes.
