Women's fitness specialist and runner Zoe Cowell-Jones has been trialling our Girlfriend Collective leggings. Read her thoughts below.

When choosing a pair of running leggings there are a few things I look for. They need to:

• be supportive and a little bit compressive (can't cope with a baggy legging!)
• stay up with zero roll down at the waist
• be breathable and sweat-wicking
• have pockets for my phone, keys and fuel

So with my criteria in mind here's my review of the Girlfriend Collective pocket leggings:

These leggings stay put. They do not roll down in any way and I feel supported but not restricted as I run. The perfect combination.

The two hip pockets are great; one for the phone and the other for anything you might need like keys, gels or other fuel. No need to faff with back pockets and zips as you run.

I've done a few long runs (up to 2 hours) in these leggings. They stayed up, I was warm and dry - but not too hot, no chafing and with the right amount of support for my leg muscles.

Size wise, according to the size guides I was between sizes so I opted for the smaller pair. They looked tiny but when I put them on they really are an amazing fit. They're not just great for running, but any gym work or strength and conditioning that you might do. Highly recommended!
