Why We Like The Crater Lake Short-Sleeve Top

On the longest days of the year, we require sun protection that doesn't wear out, so we don the Crater Lake Short-Sleeve Top before hitting the trail, river, or city. The performance fabric is rated UPF 50+ so that we don't have to fuss with sunblock throughout the day. Raglan sleeves and underarm gussets keep us active, no matter the day's agenda.

Love the crater lake material

This shirt runs a little large compared to the crater lake long sleeve crop. I typically wear a small in everything mountain Hardwear (occasionally a M if I want a shirt to fit a little more loosely). I own this shirt in both small (electrolyte) and XS (blue). The XS is definitely the better fit in this style and fits me perfectly without being tight, but I don't mind having the small as a baggier option either. Very lightweight and comfortable material--I've found its cool in warm weather but also provides a (small) amount of warmth if it's cool. The shirt did pill a little under my hydration vest the first time I wore it, but that doesn't seem to have impacted the integrity of the garment, just the aesthetics.

Perfect summer tee

Love the material! Very smooth and silky. Quick dries, looses wrinkles, and not see through. Shaped fit is flattering.
