Only worn twice for a total of about 4 hrs! I am a women’s XS and this fit me well aside from the sleeves being a little short, I am 5’11” for reference. Size XL (18) in girls - would also work great for juniors! The North Face Denali Thermal Jacket takes all the style and performance of the classic Denali and makes it unbelievably soft. The Denali Thermal offers the same warmth, fit, and signature abrasion-reinforced shoulders, chest, and elbows that define the Denali style. but the super-soft, high-loft fleece is what sets this jacket apart. The abrasion-resistant panels keep the jacket looking like new even after long days carrying backpacks, leaning on elbows, and otherwise living in the jacket, and the Denali Thermal for girls is also easy on the planet. This jacket comes with the bluesign® seal of approval, which means it’s environmentally friendly. Soft and warm enough for lounging, but breathable and flexible enough for playing, this might be winter’s most versatile jacket.
