Good quality softshell mid layer - Ultralight SoftShell Jackets – Xiangyu

The ultralight Softshell Jackets are marketed primarily to trail runners, they are often a better choice than a heavier, bulkier rain jacket for dayhikers, climbers, and lightweight/ultralight backpackers who don’t expect to encounter heavy rain.

Although they certainly look very minimalist, they deliver all the protection you need from wind, because standard, heavier, waterproof-breathable shells are, by definition, not as breathable as shells that are simply water-resistant, they are not the best choice for activities where you sweat a lot, like running or rigorous uphill hiking with a pack on, because they often cause you to get soaked from perspiration.

This ultralight softshell jacket is lightweight enough to be perfect for cycling, rock climbing, and hiking but still durable enough to provide protection and abrasion resistance from the terrain and environment. With a helmet-compatible hood and an ample cut, this jacket also allows for layering underneath,  and it is a great lightweight softshell jacket for long hikes, but it is just that. Also handy if you’re a climber.

It packs down very small, making it an ideal match for your backpack’s outer pocket. It is a handy softshell that packs into its own pocket that you can then clip onto your harness.
