Got a pair of Bull-it covert evo slim cut jeans from sportsbikeshop during clearance sale last year which I believe is still ongoing. AAA rated, L2 armour for hip and knee for 10k is a neat deal, cheaper than a made in India BykeIt Alpha jeans. Wore it for about 900km in the warm winters we have these days.
First things first, this jeans is incredibly comfortable both and off the bike. That 1% spandex sure works wonders. The knee and the hip armour will complain if you try sitting cross legged on the floor though, not a candidate for pilgrimages for sure. Second thing I noticed was it is stuffy. It does not have the massive gap that a regular cut jeans has, to let air in through. It has been a decade or so since I've tried out slim fit jeans so it could just be down to that but the stuffiness never extended to sweat in my leg at any point even in stop and go traffic at 28c ambients.
So why get slim fit jeans? I had issues with knee armour fit with my alphas, and bull it had an incredibly detailed size guide (no longer available, they seem to be undergoing some major product overhaul) that had an inch or two difference laterally at the knee and the slim cut fit my legs better. I had some doubts on the inseam measurements and how that would affect the knee armour height, I decided to wait and see how the short length works for me before buying another pair in a different colour.
The 30 short is a straight formal kind of look on my 30"-32" inseam (depending on whether you measure till the ankle or the floor) barefooted. It scrunches up a little once i put any shoes on (not sandals or flipflops) which is just how I like my pants to look. Standard 4 pocket design, rear pockets are a bit small but quite functional nevertheless. It also has a watch pocket to keep earplugs in.
The knee armour pocket has two sleeves one below the other for armour height adjustment, so you can indeed have one armour placed on the lower level and one on the higher level if you have mismatched legs like I do. The pocket is then closed with a velcro strap. The knee armour itself is curved, the kind you see on most riding pants really. Everything screams oh hey this is a rynox jacket in terms of jeans design. It is all unremarkable until you try the pants out. The flex armour from sastec is either complete rubbish or our Indian companies have not figured out how to use it correctly. The sastec armour flexes for sure, but never correctly. The armour was probably designed for a wider knee given the looser cut of the alphas around the knee. I expected the flex armour to flex cylindrically covering my knee in both directions but it turns out it can flex only in one direction so it folded on the outside gap, instead of wrapping around like a knee slider. Between that and the lack of height adjustment the knee armour was useless for me. The covert evo solves all issues with knee armour placement for me and has a reassuring presence compared to the sastecs. I only wish the armour was larger on both sides just for my peace of mind.
The hip armour fit is another issue that I came to later understand in more detail on my alphas. The alphas has a floppy hip pocket that can slide around which I used to get proper fit. But I use a belt to secure my pants which are an inch thinner than the pants and this brings the hip armour forward. Unfortunately, both alphas and covert evo run a little loose at the waist, so I have issues with hip armour fit. On the alphas I push the hip armour to the bum and pray it does not slide when I get on the bike. On the covert evo which does not have floppy hip pockets, I offset the pants to cover one of my hips at the expense of the other.
All this aside, if you want absolute impact protection you should still continue riding with riding pants (cheap) or leathers (expensive and uncomfortable) or get the mo'cycle airbag jeans, because these armours are smaller than the ones that come in full riding pants. This is very likely better for abrasion resistance than Indian brand riding pants which ironically makes it my choice for touring too.
Finally, lets talk about the price. It retailed for 160GBP-ish including VAT. That puts it pretty much on par with the made in India Bykeit Alpha jeans (no customs for us Indians). My fit issues aside you still get better kit on the Bull-it. AAA abrasion resistance that is actually certified by european bureaucrats who I trust infinitely more than our immoral bureaucrats, compared to the 'only AA' self-rated resistance on the Bykeit. It is sad that Indian companies do not get their gear CE certified, by which I mean the entire garment, not just using CE rated armour and calling it CE rated.
It was truly shocking that it costs only a measly 1200GBP to do so, and they cover all colour designs and graphics. I hear that ISI helmet homologations cost 250k INR for each size in each colour, this is remarkably cheap compared to that, tested in Europe no less. The silence from Indian bike reviewers about such gear is quite deafening, of course I wanted yet another comparison video between a Continental GT and a KTM 390. Some international media outlets like cycleworld, revzilla typically list gear their staff wore for certain outings, some run comparo articles like MCN. Coming back to the price, these jeans are made in the same countries like Bangladesh, Pakistan, India and Vietnam, but pound for pound Bykeit alpha is so much more expensive, so why do Indian dealers not stock these good, cheap brands. We get some great bikes at some great prices but man is it getting harder than ever to enjoy them safely.

AAA abrasion certification. The mesh like lining I think is additional reinforcement on impact zones.

The two horizontal lines are where the sleeves for height adjustment are located inside.

Bykeit alpha in comparison has no such thing and you have to stick the armour in and out rather barbarically through a gap in the middle. This product would be pulled off the shelves in Europe immediately if customers started returning the armour using the 2 year guarantee. I don't know what the white powder is and where it comes from because surely dust cannot get into the insides of a pant right? It is not from the armour for sure.

Hip armour is more or less the same size but the sastec armour does not fit quite right in the covert's pockets

Similar story here for the knee armour. I rode some 30km with one keep armour and one sastec armour and the sastec armour behaved quite similarly to how it does on the alphas, so you can fit the sastecs in if you prefer that.
P.S: If anyone can help me get some gear stuck in Europe please DM me.
