Is the Lululemon Smooth Spacer Quarter Zip worth $138?

It depends on how much you value the fabric. The spacer knit has more structure and a cleaner look than a standard fleece sweatshirt, but $138 is steep for one layer. If you wear it several times a week, the cost per wear is reasonable.

It is cut as a loose fit, so it runs roomier than Lululemon's slim training tops. Most shoppers can take their usual size for a relaxed layer, or size down for a closer fit.

What sizes are available?

Listings show XS, S and XL, plus US sizes 8 and 14. Mid sizes and other colors are not listed at this price.

Is it warm enough for winter?

It is a mid-weight spacer knit, so it works as a fall or mild-winter layer and under a jacket. It is not a substitute for a heavy coat in cold weather.

When is the best time to buy it?

Lululemon marks down seasonal colors and end-of-season stock, often around late summer and after the holidays. Black core colors are discounted less often.
