I was thinking about purchasing a custom sac, but I came across this skylon locker sac and it is simular to the custom one in which I was going to order. It's 19" wide and 58" long, but my question is the heigth. And how good it is.

What's the weight of it full?

I've had one for four years in the trunk of my Epic. It is supposed to get to 1000 lbs, but I kinda doubt it weighs quite that much. I fill it until it is about 24" thick, very full. The cover split and was discarded long ago. It is sort of flat and wide but gets round if you fill it enough. It is very stretchy and durable.

I have this one: <BR><a href="http://www.marine-products.com/singlestore.php?cid=393&amp;pid=2523" target="_blank">http://www.marine-products.com/singlestore.php?cid=393&amp;pid=2523</a> <BR> <BR>and it's probably about 450 lbs when filled to the size of the cover.

Thank's guys. I ordered one. A custom sack would have been 100.00 more than this sac. This sac is bigger taller than I need, but I wont fill it up all the way.

Mine is only that tall because I forget to shut off the pump!!

I use that sack. I use it in the trunk of my Air. <BR>I havent realy used any other sack's so I cant realy comment on how it works. I do think the location of the fill holes is wrong. but if your not filling and draining all the time you will be ok. <BR> <BR>If your looking for a cool sack check out the Tusnami Fast Sack system is a quick fill and disconect system,
