The Rab Nucleus Pull-On is a Thermic fleece mid-layer with a half zip. Stretch mid-weight fleece provides insulation and mobility. 

Rab says:

The Nucleus Pull-On is a mid-weight fleece with stretch, offering all round insulation for walking, scrambling, and climbing in cold conditions.

Comfortable and very wicking, the Nucleus Pull-On is made with Thermic™ stretch mid-weight fleece with an oval-grid back. A perfect midlayer, the Nucleus Pull-On will sit comfortably over a baselayer and under a hardshell, moving moisture through your layers and away from your skin, ensuring you stay dry and warm.

Featuring a deep venting half length front zip, and a zipped chest pocket, the Nucleus Pull-On provides all round insulation and mobility for everyday adventures and all mountain use.

This latest version of the Rab Nucleus Pull-On has had a few tweaks. The fabric has been updated to a Thermic stretch mid-weight fleece with an oval-grid back from the original double knit fleece fabric. This is a little more durable and has a slightly harder face to it which should wear better, preventing the dreaded pilling. We would say this fabric has made it a little warmer and the overall styling of the jacket has been updated for a better fit.

The new fabrics provides warmth and effective moisture management so it can be worn as a baselayer in colder conditions. It uses different textures on the inside and outside to improve performance. The outer has a smooth durable surface and the inner has a grid pattern that provides warmth without compromising breathability.

The flatlock low bulk construction ensures it will layer exceptionally well and the soft, wicking fabric feels cosy next to the skin. It works perfect as an outer layer when climbing or hill walking in warm conditions, or underneath a larger layer in colder conditions.
