The THERMO GRID fleece fabric features a brushed grid back construction to manage moisture and to regulate heat effectively, and an under helmet hood offers added protection from the elements when you're out on the hill.

This all works well if cold air isn't rushing over the upper face fabric causing all that heat to transfer to the outside via convection. It uses a bi-component knit construction featuring different yarns on either side of the fabric, this creates two faces: one that is optimised for moisture-management and movement and one that is optimised for quick-drying.If you want a high quality, warm and light base-layer for trail running or backpacking that adds flexibility by doubling as a mid layer, then you’d not go far wrong with the Montane Allez Hoody if you can afford it!

The Montane AMP, when worn on its own, is not quite as warm as the Odlo top and its face fabric has a pretty open-weave (whereas the Odlo provides some wind resistance via its tightly woven front panel), so the Montane AMP works best under a wind-resistant layer like an insulated jacket or inside a sleeping bag. Exceptional product as a performance weight ratio, it dries quickly and lets the skin breathe and dress slim. The Montane takes up almost half the space and weighs substantially (58g) less (on a large to large comparison).
