First off we've been doing a lot of night riding (mainly due to the short winter days) and consequently lighting has become a high priority. When I started riding again last year I bought a cheap Chinese LED light off ebay and this has been the mainstay of my set up. The lamp unit itself is quite reasonable and gives off a nice bright beam which is a little bit narrow to be perfect for use on it's own. The battery pack is made up of four lithium ion 18650 batteries in a 2x2 set up (two batteries in series wired parallel to the other two) and came with a basic UK plug charger. There are a few scare stories on the internet about these Chinese battery pack/charger combinations overheating and catching fire so I've been very careful while charging the pack (frequently checking for any heat build up and ensuring that I unplug the charger as soon as the batteries are charged) and charge the batteries in a substantial metal box just in case. So far though I've had no problems and run times have been decent, easily coping with the two to three hour rides we usually do.
Back in the day I was an avid user of clipless SPD type pedals but latterly (before my break from mountain biking) I converted to riding with flat pedals and skate shoes. From the outset I intended to stick with this option on my fat bike but I've found skate shoes a bit lacking in grip on hike a bike sections in slippery winter conditions. I played with using my walking boots and trail shoes but these were both Goretex lined and I found water tended to run down my legs into them negating any advantages of having waterproof footwear, On a recent trip to Decathlon I took a punt on a pair of non-membrane mid height trail shoes which were reasonably cheap. I've been wearing these in combination with some Sealskinz waterproof socks and they've exceeded my expectations. They're comfy, supportive, have decent grippy treads for walking and surprisingly grip my DMR V12 pedals really well (at least as well as my skate shoes which surprised me). They also dry quite quickly which is a bonus as my skate shoes were almost perpetually soggy!

I always hated riding my mountainbike with thick gloves on and usually put up with freezing hands in winter rather than sacrifice the feel of using my minimalist summer riding gloves. The pogies may look ridiculous but they work superbly keeping my hands toasty even when my gloves are soaked (they don't keep the rain at bay for long) and surprisingly most of the time they don't feel awkward or clumsy (the only time I've found them inconvenient is when I've wanted to adjust my lights or riding glasses while on the move, it's still possible but requires a bit more care). A side benefit is that the reflective strips on them really show up well in car headlights, something I noticed while passing my riding buddy Rambo in the car while he was going in the other direction (he bought a pair as soon as he saw mine).
I'll hopefully do some more kit updates in future and if the weather settles down again and my new tent arrives (which I'll also review) I'll try to actually get out bike packing soon. In the meantime here's a video of Rambo and I night riding in the snow recently (before I bought the Fluxient light)
and a solo ride around the Menteith Hills that I did.
