Versatile as base or mid-layer, 07 January 2017
By TriedOut (Reading)
Great piece for all sorts of activities. The grid backer gives a warm, soft to skin feel and wicks well as a base / solo layer eg for me running at around zero to 8 deg C. Sizing: I have a 38 inch chest and the small works well as a base layer with just enough room for another thin base layer when using it as a casual piece. You'd want to size up to use it as a regular mid-layer.

I tend to be cynical about anti-odour claims but the Polygiene silver treatment really seems to work. Most of my base layers are in the wash after every single use but this has withstood multiple uses as a base layer - in high output exercise in SE England December temps - without any noticeable odour.

I love this Rab top, it is light weight & very warm, the vent zip is also a nice touch. Perfect for layering up.

Great piece of kit, 24 October 2015

Had this fleece now for a couple of weeks and I could not be happier with it . Quite thin to go under an outer garment but very warm. Great bit of kit .
