Ergonomic fit, temperature regulation, and moisture management team up in the Pearl Izumi P.R.O. Barrier Arm Warmer to keep your upper limbs cozy. The key to the Barrier's functionality is Pearl Izumi's wind-resistant P.R.O. thermal fleece that's constructed with Minerale, and an anatomic design.

Already well respected for its warmth retention, Pearl's thermal fleece has been updated with Minerale. It's a fabric manufacturing process using both natural and synthetic materials to produce a highly porous structure. This increases the garments surface area for faster perspiration evaporation, keeping you dry and comfortable.

To ensure maximum performance, Pearl Izumi designed the P.R.O. Barrier Arm Warmers to be left and right specific. They also use multiple, specially shaped panels to offer a next-to-skin fit that's not restrictive to either movement or blood flow. The warmers also use an elastic binding with silicone grippers and a scallop interface with tops to prevent exposed skin or migration.

Finishing off these arm warmers is reflective piping, highlights, and logos to add low-light safety. The Pearl Izumi P.R.O. Barrier Arm Warmer is available in sizes X-Small through X-Large, and comes in either Red or Black.

Good gift for the man with everything.

  • Familiarity:I gave it as a gift but have feedback to share

I gave these as a gift for my father-in-law. He has everything, but I figured he wouldn't have some arm warmers. Turned out great.


Very good arm warmers

  • Familiarity:I've used it several times

I purchased these to replace a pair of PI arm warmers I purchased about 10 years ago that were essentially fleece-lined lycra tubes. The anatomic shape of these warmers creates a very nice fit. Following the sizing chart provided in several websites including Pearl Izumi I purchased a small for my 12.5 inch arms. They are snug at the top but will not slide down and the length is very close to correct. On the road they are very warm but breathe quite well. The shape allows them to fit so well I don't notice I have them on except for the fact I'm warm. Overall excellent performance.



    Bought these Pro Barrier Arm Warmers as upgrade to Thermal Lite arm warmers. Used them in 50-60F conditions. They were amazing on a long cold descent. Felt zero wind chill. Fold up nice and small so easy to stash and prevents needs to bring along a full sleeve jacket. The fuller length gets right under a jersey sleeve so no gaps exposed to wind. I will use them with a short sleeve jersey and sleeveless wind vest. Great for temps down to 45F, beyond that I would need more solid body covering. Recommend for cool-cold days but not for freezing days.
