I bought one of the torches today, but I have to admit, I was a bit disappointed. Its well made, but there is a gap between the front of the torch head and the knurled part where the switch is , and its got glue in it, which is not the greatest craftsmanship. The switch is a pain, and really easy to click on, even when putting it in the pouch.
On the other hand, its slightly brighter than my Romisen Q3, although its actually a Q2, and fine for upgrading relatively cheaply from an old incandecent. If you have a drawful of cheapish brights, your not going to miss this one. Frankly, its not £10 your going to be able to spend on a Fenix.
The insulated trousers are good , although the padding on the inside does make you feel a bit like you've wrapped your legs in a barbour gillet, and its a bit noisy, thanks to the teflon , but great for when the snow hits. The sizes are not clear, but a medium is about a 32-4 waist (and there are elastic straps to loosen and tighten), and a 32ish leg.
I gave the thermals a miss, but a set for £8.99 is a good deal, and quality was pretty good.
