FAQS

The main difference is the unique weightlifting belt attachment. This feature allows the bag be used as normal, while carrying a cumbersome lifting belt on the outside. Other changes are the volume (35L) and the layout.

Most of the materials are the same as used in other King Kong bags. YKK zippers, heavy duty buckles, nylon lining and webbing are all the same. In the CORE range, we have gone for a lighter 500D nylon outside and a new velcro logo feature that allows you to go 'incognito' with your own patches.

Measure the widest point of your belt and its length.

The CORE35 (medium) duffel can fit a belt up to 6.3"/16cm wide and 45.7"/116cm long.
The CORE51 (large) duffel can fit a belt up to 6.7"/17cm wide and 45.7"/116cm long.

A lever belt can fit, but you should count the lever into your measurement.

The CORE35 (Medium) will fit size 12 shoes. The CORE51 (Large) will fit size 15 shoes.

    Love It, But Made Some Tweaks

    Got the 35L for Christmas and have been using it 3/week as my gymbag for 2 months now.

    Pros:

    -Overall the construction and material are very good.

    -The organization of the bag is incredible.

    -Everything feels 'easy access.' I never feel like I'm digging for my wrist wraps or wasting time.

    -The belt storage is a great idea. Shows off my powerlifting belt nicely and keeps it secure.

    -The 35L model is the perfect size to hold everything I need to workout, plus extra clothes and toiletries as well.

    Tweaks (I don't have any major cons so this section is tweaks)

    -The shoulder strap squeaks when you walk with it. I found putting tape of the strap anchor points and using rubber bands as makeshift O-rings in the swivel joint silenced that.

    -The belt holding straps on the side have velcro on the inside to keep them from flopping around when not in use. The velcro does seem to fray my belt a little when getting it in or out; mainly at the bottom. I put tape down there to keep the velcro from eating at my belt and it seems to work.

    Overall I'd recommend this bag, although one or two tweaks would make it amazing.

    Love this bag!!! I had a medium size Nike duffel at one point. As my gym sessions increase that’s when I knew it was time to upgrade. So much room for everything you need and then some. Only thing that does bother me with the bag if it wasn’t for this it would be 5 stars. Maybe it’s just me, side zippers run in to the shoulder strap clips on the top side of the bag. When I go to zip a side pocket it runs in to those clips. Not a deal breaker still a great bag would recommend to anybody for sure 4.5⭐️⭐️⭐️⭐️✨

    All around a great bag, few flaws imo.

    All in all, I feel like this is a great bag, though I've only been using it for a couple weeks. From what I've experienced, I would recommend this bag to most people. I like that it's a bit more rigid, the fabric is thick enough that it doesn't collapse on itself. Pockets are well placed, I like a lot of the features, and I have no regrets about the purchase.

    The two complaints/considerations I have are that the zippers are lighter grade than what I feel the rest of the bag is. When I'm tugging on them, it feels like they might be the first thing to go on the bag. Especially on the side pockets, I would love more burley zippers. Secondly, I feel like it should note on the product information portion that the shoe pocket doesn't fit size 13 or larger. This isn't a big deal, as I've always thrown my shoes in the main compartment, however I feel like it would be nice of the company to disclose that so that people know. That being said, it's still a nice side pocket for other things, like a damp bathing suit after swimming.
