I've bought many running tights from other places but these tights beat them all.

Run warm Kalenji running tights
Used for 2 to 8 weeks
I speed walk rather than run but have found the Kalenji run warm running tights fit well and keep me warm even at around 2 degrees Celsius. I have also worn them under trousers as an extra layer in cold weather.
Great product
Used for 2 to 8 weeks
These trousers are great and keep you warm when running in colder weather.
I would recommend you buy a size up to what you normally wear. I am usually a medium but all Kalenji items I have purchased are large.
Cheap tights and great value
Used for 1 week or less
These are the cheaper tights, they are simple in design and do not offer (proper) compression. However, they do act as an excellent underlayer or good for running in mild weather. Great value tights.
Comfortable and warm
Used for 2 to 8 weeks
I was advised by my physio not to run cold in the winter, I'm a 5am runner, so I thought I'd try these. Instant convert, great compression, warm, breathable and very comfortable.
Excellent warm/thermal leggings
Used for 7 to 12 months
never ran in leggings before! but these were perfect for temperatures 2c and lower. keep your legs nice and warm and with no loss of movement or rubbing. make sure you try them on in the shop to get the fit right. possibly go one size up. the price is amazing .
