Phase SL Bottom

Powder-seeking ski tours, brisk morning runs, or mid-winter bike rides—it's all fair game for the Arc'teryx Men's Phase SL Bottoms. Designed for high-output activites in cool weather, these superlight tights wick sweat and dry rapidly to rid you of heat-robbing moisture, while moving effortlessly with your every movement. The Phasic SL fabric is also highly breathable to keep you from getting too stuffy, and the next-to-skin fit maximizes the fabric's thermal efficiency and moisture-managing properties.

  • Gusseted crotch enhances range of motion

I wear leg insulation almost everyday October through May and alternate these with 8 other pairs of various brands. These are great except for the seam split right where your valuables fall through and become very very uncomfortable on the other side. They have not lasted as long as my other brands do, or nearly as long as I would expect from a company that touts itself as the premier outdoor clothing manufacturer.

Warm Weather Base

This is my warm weather base for skiing. They're great, I only wish there was a merino layer at this weight.

I purchased this product recently and have worn it about 7 times for running, cross fit and pilates. It has only been hand washed. It has started to sag, especially at the knees, and some of the stitching at the ankle has broken loose. I have many arcteryx products, unless I am doing something wrong, I cannot recommend this product. As of July 13, it has developed runs making it useless.

Super Light Super Warm

The bottoms are only 3.5 oz but they keep you so very warm during the bitter cold months. I have worn these boarding and biking. The Phasic SL fabric also does an amazing job of whicking away sweat. These do really well for those nights where you are feeling brave and decide to make the trek to the bar on foot.

Keeps you warm while still extremely breathable. Fit is great, can't even hardly tell you have them on. Going in my flight bag.

They will make it into my standard bike-touring kit when travelling outside of high-summer.
