Last but not least in the parcel of goodies from As Tucas was some Foratata down booties. At €60, they compare favourably with similar offerings from the likes of PHD. They weigh 61g for a medium size.
As you can see from the picture, they have good loft. For my size 42 feet, the fit is good. As ever, the workmanship is first rate. I can see that these will be a permanent fixture in my gear list for cooler months.
Disclosure: I bought these booties at full price from As Tucas with my own money.
