OVERVIEW: The Keystone Vest is designed with the classic Colorado shoulder season ride in mind. Imagine your morning rollout in the mid 30’s, by lunchtime you're faced with temperatures hitting the 70’s, and the entire course of the day you've encountered mountain ascents/descents that expose you to extremes at either end of that spectrum (and probably some rain too!). The Keystone is extremely effective at regulating your temperature while being light enough to wear through the entire effort (even though it will easily pack into a jersey pocket). And if you tend to run hot during exertion, we've included a reflective two-way zipper so you have venting options. Three full-size rear pockets and a fourth zippered security pocket allow you to stow everything you may need for an all-day ride.

FABRICS & CONSTRUCTION: The versatility of this midweight, stretch vest comes in the form of the stretchy, body-hugging softshell, which is both windproof and highly water resistant, and a super light-weight stretch knit, which efficiently regulates body temperature across the back. To enhance the versatility of this multi-season garment, we have used an environmentally sensitive C6 DWR (durable water repellent) coating on all the external fabrics to facilitate the repelling of road spray and rain. 


  • 3-Layer stretch-laminate, softshell fabric on front, shoulders and collar for windproof/waterproof protection
  • Lightweight, highly breathable, stretch-knit across back
  • DWR (durable water repellent) coating throughout for water shedding
  • Three full-size pockets
  • One zippered, water resistant valuables pocket
  • Reflective two-way YKK zipper with weather flap and discrete double-sided zipper garage for neck comfort
  • Reflective taping on shoulders
  • Reflective pocket taping for 360° visibility.
  • Temperature Range: 40° - 70° F

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.

Good but not excellent quality, VERY short, has flimsy zipper

My first and hopefully only "meh" purchase from Pactimo. I had high hopes. Pretty well constructed, the fabrics are solid: thick, windblocking and water shedding on the vest front, a high neck and (hooray!) standard jersey type back pockets (hard to find on vests!) But the zipper is flimsy and cheap, and the vest is SO short that all but my most "aero/****" jerseys peek out by at least an inch and a half all around under the vest bottom. I can't wear it with shorts or tights, only bibs since they come up higher in front. I won't be able to wear it much and only decided to keep it as a chilly weather emergency back up if anything happens to my Castelli perfetto vest.

Runs very small, need to size up

This is a great vest that definitely makes me more comfortable in cold weather, but definitely requires sizing up.

Great alone or for layering

Our SoCal winter is not very cold! I used this vest during the winter to layer over my Divide Jacket, or by itself (as it gets warmer). I will probaby wear it under my Keystone jacket when we get to the colder days! Love this versitile vest. AND bonus - it has pockets!

Wish I had this two months ago

This vest is money. Keeps your core warm with out over doing in the weight or flapping like other brands I have worn.

Nice vest, runs very small

Ordered this vest for my wife. She is reliably a size medium in almost everything (not just bicycling attire). This vest was very tight all the way around. It is otherwise well made and good looking. She had concerns that the next size up would be too long (tall) for her, so we simply returned it for a refund. The return was handled quickly and without issue.
