K-Tek Stingray MixPro

This bag is sturdy and comfortable to use because it is really light and not bulky at all!
So in my opinion no doubt it is a really good tool made with high quality materials, but I want to warn potential buyers about this:
my advice is DON'T BUY IT if you power your mixpre with a L-series type of battery!
The MX-L battery sled will fit perfectly into the bag (it actually keeps the mixpre steadier) but the battery won't, because the bag's width is 51 cm only. I use a SWIT battery which is particularly big (8 cm width) but I think any other battery, even smaller, wouldn't fit inside.
The internal dimensions are indicated so, of course, this was totally my mistake because I didn't pay enough attention when I purchased it. So I ended up returning this and buying a bigger bag, no big deal but I hope this review can be helpful and prevent someone to do the same mistake

Got this and the MixPre-6 II for field recording.
It feels very robust, it has an internal rigid frame and a couple of velcro straps suspend the MixPre keeping it secure inside.

Without the front pocket attached it’s sleek enough to feel like a typical satchel bag or would even fit as a large bumbag. The strap could do with more padding.

It’s quiet enough when not being adjusted but; the zippers are smaller rounded type that can’t be opened silently, the velcro is loud with a strong grip, the material could be quieter it has that low ‘O’ (around 500Hz) rustle typical of nylon duffle bags.

All six sides can be open to access. The bottom for battery/SD access and front (for mounting camera) requires decoupling the largest area of velcro so this needs modding with tape if you’re working in quieter environments. The top has a detachable transparent piece that looks okay but the way it’s attached feels a bit of an afterthought. The back hole, for accessing tripod mount point (though I’ve my USB battery in the way there) has no cover which is a shame.

So overall could do with some improvements but I only know of two bags that fit the MixPre and this looks the better of the two.
