Mountain Equipment Senja Insulated Jacket Obsidian Large

The Mountain Equipment Senja Insulated Jacket in Obsidian is a high-performance synthetic insulated jacket designed for cold weather climbing, mountaineering, and hiking. Featuring POLARLOFT® Featherless insulation and a PFC-free DWR finish, it provides warmth, wind resistance, and packability without the use of down.

Advantages

This jacket offers exceptional warmth-to-weight ratio, thanks to the synthetic POLARLOFT® insulation that mimics down but retains heat even when wet. The recycled 20D nylon outer and lining are lightweight yet durable, and the jacket packs into its own hand pocket for easy storage. The adjustable insulated mountain hood and elasticated cuffs seal in warmth, while the YKK® moulded centre front zip ensures reliable closure.

Suitable for

• Climbing and mountaineering in cold conditions
