The Atom LT Vest is quite simply one of the best lightweight and versatile insulated gilets available. It features a lightweight face fabric and protective collar design. This fantastic vest can replace layers of bulky fleece with one super light, unrestricted and warm layer. Filled with a highly efficient synthetic Coreloft insulation it provides enough warmth for active cold weather pursuits or can be used all year round when the temperature drops.

The Tyono face fabric used to construct the Atom LT is a 100% nylon 20D fabric with a DWR (Durable Water Repellant) finish. The DWR finish makes this brilliant vest highly weather resistant, keeping out all but the worst wind and rain. 100% Polyester stretch side panels provide fantastic freedom of movement, incredible durability and give an anatomical efficient fit whilst enhancing breathability under the arms.

The Atom LT Vest features a collar with a soft brushed lining that sits mid-height so it will layer really well whilst still offering enough protection around your neck when you wear it on its own. 

Insulated with 60g/m² Coreloft, an incredibly efficient and packable synthetic insulation that performs even when wet and will dry out exceptionally quickly.

This garment has the Arc'teryx “Trim Fit”. Trim fitting garments share motion-friendly traits with the “Athletic fit” but are patterned with lower volume for reduced bulk. The trim fit is sized for a base layer and a trim synthetic or down filled mid-layer.

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!
