This Micro Umbrella by Totes is compact for putting in your backpack or purse. When deployed, it is as big as a full-sized umbrella. I've had my Totes Micro Umbrella for a few years and it's held up to strong winds and heavy rain. It may not be the the spring-loaded kind that opens up automatically with the press of a button, but it folds up very compact (approximately 8-3/4" in length and 5-1/2" in diameter). The craftsmanship is superb, from the stitching on the velcro strap and the canopy, to the skeletal frame and the telescoping handle - the quality is simply top-notch. The Micro Umbrella is, in sum, practical, well-made, durable, and *compact*. I'm extremely pleased with it. Definitely recommended!
