If you have a Bag Boy cart you should have taken a look at the Bag Boy bag with their lock system. It will literally lock your bag to your cart without straps, etc.
I just bought the Bag Boy Chiller bag from TWC for $135 including tax and shipping - sale price. One of my reasons is that it is one of the few bags that worked well for jumbo grips with the full length dividers for each club. I wanted the chiller to take a few drinks in my bag when I play and I liked the fact I can take it out of the bag when I don't need it. My home course allows coolers, but another course I play often does not. I tend to ride a cart most of the time, but one of my friends has this bag with a Bag Boy cart and loves the combo. I tried my jumbo grips in his bag and it worked great. I also found positive reviews on this bag regarding jumbo grips.
I did consider the C-130 , a 2016 model, as it can be had at TWC for $154 shipped less tax. However, this bag is exactly what another friend has and loves it. I tried my jumbo grips in it and it would hang up unless I was really careful in extraction. I opted for the Bag Boy.
If you have a new bag consider using a product named RayandSun on it. I have done this over the years and it really makes a difference in fading and works well to repell water. I use this product on various other outdoor products with excellent results, patio furniture, patio umbrella, a golf hat I use only when rain is a possibility, etc. Best price is at Amazon. I don't spray it on smaller items as there is too much over spray, but use a small brush for even coverage and no waste. It is best with two light coatings and let it dry well between coats. It does put off a chemical odor for a few days. My bag is presently drying in the garage. Another item I use and love to have around is Tribology Silicone Paste. It was recommended by a friend some years back. Best product I have ever found of this nature. It works great on zippers of a golf bag, etc. and I particularly love it for my cart cover. But, you can use it for a wide variety of applications, auto, marine, and is excellent in plumbing applications. It seems a bit expensive, but the 8 oz size last a long time. A very small amount of it goes a long ways for most applications. As soon as my new bag dries of its RayandSun treatment I will be lightly lubricating all the zippers. Again I get it at Amazon.
