The Sirro is a versatile mid-layer that is stretchy, comfortable and breathable but also comes with zoned insulation so you can be confident it will perform in a wide range of conditions. 

Haglofs says:

Great for mountainside activities - no matter how tough. It's a hybrid mid layer that's made with a stretchy knit fabric with micro-grid backer, then body mapped and packed with high-loft QuadFusion™ ƞ. As a result, it's warming and effective, as well as comfortable. No shoulder seams - reducing the risk of chafing against the rest of your gear. Thumbholes on the cuffs help keep it in place and add to the comfort level.

Haglofs' Sirro Mid Jacket provides comfort, warmth and breathability when you need them most. This top is super lightweight for the design. It has zoned insulation where Haglofs have use the most advanced version of their synthetic QuadFusion ƞ which provides great warmth to weight. The main body of fabric is the lightweight, stretchy and super comfortable Pontetorto Technostretch fleece which is a favourite amongst our team.

A number of practical features make this a great mid-layer top. The full length zip is versatile and allows you to open it right up and ventilate when things warm up. There is a single small chest pocket to minimise the weight, while the lack of shoulder seams increases comfort and durability, and who doesn't enjoy thumb loops on an active wear top? The Sirro is perfectly suited to a wide range of fast and light activities.
