This is a great all around shooting bag. I used it in the military when I had to attempt to pick a "one size fits all" rear back due to a lack of space on my kit or persons. This bag is large enough to rest on top of most barriers, walls, ledges etc.. and act as a rest. As well as soft enough to be manipulated into a rear bag when shooting in the prone. Not to mention it was a great seat cushion during long helicopter rides.Very light weight easy to carry around. Easy to shoot prone now . Hi quality construction fill is nice and soft .Sold construction. Perfect size for use with a 6-12 inch bipod. Well thought out design, works in multiple positions. 10 Stars.Aside from the two reviews that for some reason or another didn't receive with poly fill(bought the modular bag instead maybe that doesn't come filled?), this is hands down the best rear bag I've used. As you can see from the reviews here it's well worth the money. The pump pillow is nice, but it's just that...nearly the size of a pillow. This todd tac pad is perfect! Of all the rear bags out there, this is hands down the best in my opinion. It's super light. It holds shape and can be turned to different sides to accommodate different setup heights. It's a versatile shooting bag you won't regret buying.I actually was sent the incorrect product on this order, so I did not receive the Tac Pad HOWEVER I've used a friend's and I can say it's a great product.I did however receive the modular pump pillow, which I just decided to keep. The modular pump pillow is the item that has a zipper and allows you to fill the pillow with whatever material you wish to. I filled mine with old towels and t-shirts. It's great for either using as a front rest or support when firing from an offhand position. I bring mine with me every PRS match I go to now.I have the mini range cube and a small squeeze bag , although both have their purpose, this bag is the most versatile bag I own. Great for prone and positional shooting, nice material and wonderful stuffing that can be squeezed easily. This bag does not have a "tight" feel to it. Can be oriented three different ways for height adjustment. If buying one bag, this is it.This product is pretty good. It is my first so I don't have much comparison but it is very light weight and easy to manipulate under the stock of my rifle. Has helped quite a bit on accuracy.I have a 'collection' of the various Wiebad bags. The Mini range Cube was my first purchase. I now have 3 Loop Bags, 1 Pump Pillow, 1 Todd Tac Pad and 1 Mini Tac Pad, Quite the investment but it allows me the perfect set up for different rifles having the different bag sizes to chose from. Exceptionally high quality gear.
