Operation Ivy wrote a review of The North Face Tamburello Insulated Jacket - Women's on October 29, 2013
I bought this jacket for my girlfriend for the upcoming Milwaukee winter. Little did I know that North Face's Heatseeker insulation is not the same measure as Arcteryx Coreloft, Primaloft or any other synthetic insulation. The description said 120g Heatseeker, which I expected to be pretty lofty and warm. This was not the case. When I took it out of the packaging it was as thin as, if not thinner than, my Arcteryx LT (60g coreloft). The quality of the product seemed legit but definitely a mid layer type jacket. despite the North Face's deceivingly odd use of insulation weight. I will be returning this jacket and spending the extra $140 for the Arcteryx Atom SV like I should have in the first place.
