The North Face Summit Series Men's L1 Top is the base layer for cold, harsh alpine climbs. The form fitting top stays close to the body, Thermolite® fabric ready to add heat while wicking moisture. You stay comfortable and whenever you start to heat up, open the 1/2 zip to release the excess. Minimal seams to get in your way, so you move naturally, even under layers of clothing. The system works together, but it all starts at 1.

Rated 5 out of 5 by from Deserving of the Summit Series name! I bought this item because I was upgrading my mountaineering kit. I'm a huge North Face mountaineering clothing fan (not the style, but the functionality) Due to my OCD, I HAD TO HAVE the complete Summit Series layering system. The fit is fantastic, and I love that it has a zipper to help vent heat. I haven't been able to test it yet, but I can't wait for next winter to do so! I went with a large due to the sleeve length. Had I gone medium, the sleeves would've been too short. I LOVE this piece!

Rated 5 out of 5 by from A must have lightweight mid-layer The color is great and goes with everything well whether it's for an activewear/performance day or just casual. Fit is perfect. Can be used in any temperature whether it be the outer layer on a windy cool night or mid-layer for those colder days.

Rated 5 out of 5 by from Perfect base layer This was perfect. I've gone through dozens of base layers, and I either find ones that are too warm or not warm enough. This was just the right balance of moisture wicking and warmth. It fits snug, but not too tight, and the design pulls it in tighter where it makes sense. Used it on a day hike and loved it. When I got working a little hard, I unzipped it a few inches to dump some of the heat. When we stopped for a bit, I just zipped it back up. Worked great.
