OVERVIEW: Reflective Cycling ClothingArm warmers are ideal for cyclists who like to adapt to changing temperatures and weather conditions without fussing with or trying to pack a jacket. They easily pack into a jersey pocket and can be taken off or put on in a matter of seconds, even while on the bike. These warmers also feature Reflective Technology™ for added safety in low-light conditions.

FABRIC & CONSTRUCTION: The next generation Alpine Arm Warmer has been taken back to basics. Leveraging a high-stretch fabric, we simplified construction to a single seam for reduced chafe points without compromising fit. An all-new cuff design is made from fabric featuring Reflective Technology™, providing visibility from all angles. A large, reflective logo adds additional visibility in low-light conditions. We love the ThermaGuard fabric for its compressive fit and soft feel against skin. It's not overly warm while providing the perfect amount of protection for those days where you need to cut the cold without overheating. The gripper-band is possibly the most critical component of any warmer, so that's why we searched high and low for the best combination of sturdiness, stretch, soft-touch and grip. We think we've found the perfect answer with the wide, stretchy and soft grippers in these arm warmers. While they hold incredibly well on their own, we went ahead and added a tenacious silicone print to the interior (skin side) to ensure the bands stay locked in place. We recommend washing the warmers prior to wearing to activate the Silicone for best grip. Warmers work best and stay in place when placed directly on the skin, not over a jersey or base layer as Silicone is not designed to grip fabric. 


  • ThermaGuard fabric - slight interior loft, breathable, wicking and lightweight
  • Reflective Components 
  • Ergonomic Arm Openings 
  • Ultra-soft silicone gripper at upper arm opening
  • Reflective Technology™ fabric panels at wrists

Pair with any short-sleeve jersey when the temperature dips below 65 or 60°. Wear with the extremely versatile Keystone Vest and set of Knee or Leg Warmers in the 50's or even the 40's and you'll be ready for a long spring or autumn day in the saddle.


We recommend you purchase arm warmers in the same size that you typically wear for a jersey. See the size and fit chart for assistance.

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.

Alpine arm warmers

I used them for the Triple Bypass and they worked out great. I just wish the grippys were a little stronger at the biceps.

Alpine Arm warmers

Arm warmers worked great. Below 30 degrees I combined them with the Alpine jacket and stayed warm. At 45 degrees I would wear them with with the wind jacket and again would be comfortable. I definitely would recommend the arm warmers.

Great thermal sleeves

Warm and lightweight thermal sleeves. Nice reflective cuffs.

I just received the Alpine Thermal RT Arm Warmers and have not used them as of this review. However, the arm warmers are well made and are of the same quality I would I would expect from Pactimo. I have the Alpine Thermal Jersey and I am very satisfied with the performance and fit of the jersey and would highly recommend to anyone. I plan to do a follow-up review on the arm warmers after I have an opportunity to put them through the paces.

Just the right weight arm warmers!

Needed some new arm warmers to replace my worn ones and these Alpine Thermal Arm Warmers are just the ticket! They are just the right weight for those rides that start in the chill of the morning. The have a nice weight to them and the fit nicely in a jersey pocket when you no longer need them. The reflective cuffs are a nice touch too!

Too Earily To Tell

I only wore them once, they were comfortable for the whole time I was wearing them.will need a ride where I don't need a jacket over them to be able to say they kept my arms warm as advertised.

Excellent quality

They have worked great for me. Would definitely recommend them. Where I live they are mostly used above 40 degrees and have made rides way more enjoyable.

Shoulder season solved!

Can't believe I've ridden so long without owning arm warmers (and leg warmers)! Perfect for NE mornings and evenings all through the Fall. These take about a minute to get on while riding (one at a time!) and do a remarkable job of taking the chill off. I heat up pretty easily, so for me these are perfect from 40-55 degrees. They're easy to store, fit snugly without cutting off circulation, and are light and well made. In short, they're excellent.
