The North Face Lil' Crympt Jacket
Here's what other sites are saying:
Often the big issue with super-warm insulation is that mobility and breathability get sacrificed, but the design of The North Face Boys' Lil' Crympt Down Jacket puts that old issue to rest. With stretchy, breathable panels at his sides and elbows, a young man can hike, ski, and even bike or skateboard on city streets without feeling like he's being suffocated by what he needs to stay warm.
