The 100% Rcore Mountain Biking Jersey is worth considering if you want a long-sleeved jersey listed for downhill and enduro riding, but its $82.09 Amazon price is higher than the other recorded R-Core listing prices 100% R-Core Long Sleeve MTB Jersey – Planet… 100% Rcore Mountain Biking Jersey – Down… 100% R-Core MTB Jersey (SM). Its listing describes polyester mesh, moisture management and a drop tail; it doesn’t provide a washing guide or measured weather performance 100% R-Core Long Sleeve MTB Jersey – Planet….
- The R-Core line is technical riding apparel built around downhill riding 100% R-Core Long Sleeve MTB Jersey – Planet….
- The jersey listing describes polyester mesh with moisture-management properties 100% R-Core Long Sleeve MTB Jersey – Planet….
- The manufacturer-provided chest chart runs from 36–39 inches for S to 50–52 inches for 3XL 100% R-Core MTB Jersey (SM).
- Amazon lists the jersey at $82.09 and says only one is left in stock 100% Rcore Mountain Biking Jersey – Down….
What is the 100% Rcore Mountain Biking Jersey, and what riding is it designed for?
The 100% Rcore Mountain Biking Jersey belongs to a technical riding apparel line built around downhill riding 100% R-Core Long Sleeve MTB Jersey – Planet…. The line’s stated aim is to provide comfort and protection from run to run 100% R-Core Long Sleeve MTB Jersey – Planet…. Those are manufacturer or retailer descriptions, not results from testing reported in the available information.
The jersey’s product name also places it in downhill and enduro apparel, while the broader 100Percent MTB collection is described as serving cross-country, trail, enduro and downhill riding 100Percent® MTB Gear – 100%. That broad collection description shouldn’t be mistaken for a claim that every garment is intended for every discipline. A collection announcement described R CORE-X as downhill gear, while CELIUM, AIRMATIC and RIDECAMP were identified as All Mountain options Video: 100% Announces the 2020 Spring Bike…. The practical distinction is that R-Core is the downhill-centred line; the available sources don’t specify a particular trail, race format or riding level for this individual jersey.

What materials, ventilation features, and other specifications does the R-Core jersey have?
The R-Core listing specifies polyester mesh with moisture-management properties, but it gives no quantified ventilation or cooling measurement 100% R-Core Long Sleeve MTB Jersey – Planet…. The broader 100Percent collection is described as having ventilation zones; that collection-level statement doesn’t establish where, or how many, zones this jersey has 100Percent® MTB Gear – 100%.
The jersey’s listed drop tail is intended to increase coverage in the riding position, and its graphics are described as fade-resistant sublimation 100% R-Core Long Sleeve MTB Jersey – Planet…. The product information also identifies an internal goggle wipe, long sleeves, a high neck back and an extended rear hem 100% R-Core Long Sleeve MTB Jersey – Planet… 100% R-Core MTB Jersey (SM). These details sketch out a riding-oriented cut, though the available sources don’t give garment measurements.
Keep the R-Core X specifications separate: that version is listed with polyester/spandex mesh, moisture-management properties and anti-microbial properties 100Percent® MTB Gear – 100%. Those are not established specifications for the standard R-Core jersey. The standard listing says polyester mesh; it does not make the same anti-microbial claim 100% R-Core Long Sleeve MTB Jersey – Planet… 100Percent® MTB Gear – 100%.
How does the R-Core jersey fit, and how should you choose a size?
The Amazon listing identifies the R-Core jersey as long-sleeved with a straight fit 100% Percent Men's R-Core-X DH Long Sleeve…. For size selection, Cycle Gear provides these manufacturer chest ranges: S, 36–39 inches; M, 39–41; L, 41–43; XL, 43–46; 2XL, 46–50; and 3XL, 50–52 100% R-Core MTB Jersey (SM).
To use that chart, measure around the fullest part of your chest, under your armpits, keeping the tape parallel to the ground 100% R-Core MTB Jersey (SM). The chart is a starting point, not a promise of a perfect fit: Cycle Gear says its sizing information doesn’t guarantee one, and a separate sizing guide notes that recommendations and measurements vary by brand 100% R-Core MTB Jersey (SM) How Should a Cycling Jersey Fit? Try Our Size &….
If your measurement falls between sizes, general guidance recommends choosing the larger size How Should a Cycling Jersey Fit? Try Our Size &…. That advice isn’t a product-specific fit test. The available sources don’t report rider measurements, garment dimensions or firsthand fit observations for this jersey, so you can’t use them to predict exactly how it will sit on your shoulders or torso.

How much does the R-Core jersey cost compared with other listings?
The Amazon listing prices the 100% Rcore Mountain Biking Jersey at $82.09 100% Rcore Mountain Biking Jersey – Down…. Other recorded R-Core listings show $19.99, reduced from $59.00, at Planet Cyclery and $47.20, reduced from $59.00, at Cycle Gear 100% R-Core Long Sleeve MTB Jersey – Planet… 100% R-Core MTB Jersey (SM).
Those figures come from different retailer listings, not a controlled comparison. They may refer to different listing conditions, and they don’t establish a current price available to every shopper. The Amazon amount is the price recorded for that listing; the other figures are useful context, not a guarantee that the jersey can now be found for either sale price.
The compiled retailer table below lays out the three recorded prices and, where available, listing availability. It doesn’t resolve whether the listings represent identical sizes or stock conditions. If price is central to your decision, compare the current offer and the size shown on the listing you’re considering rather than treating an older or separate retailer price as a reliable benchmark.
How does the R-Core jersey compare with the 100% R-Core X?
The R-Core X is described as an upgrade to standard R-Core downhill and enduro riding gear 100% Percent Men's R-Core-X DH Long Sleeve…. Its listed features include four-way stretch materials and weight-saving materials and treatments 100% Percent Men's R-Core-X DH Long Sleeve…. Those claims belong to the X line; the standard R-Core information available here doesn’t specify four-way stretch or comparable weight-saving treatments.
The R-Core X is described as downhill and enduro gear and includes an internal goggle wipe 100Percent® MTB Gear – 100%. The standard R-Core jersey also has an internal goggle wipe, according to its listing 100% R-Core Long Sleeve MTB Jersey – Planet…. So that feature alone doesn’t distinguish the two.
Some X-specific claims shouldn’t be carried over to the standard jersey. The X listing specifies polyester/spandex mesh, moisture-management and anti-microbial properties, while the standard R-Core listing specifies polyester mesh with moisture-management properties 100% Percent Men's R-Core-X DH Long Sleeve… 100% R-Core Long Sleeve MTB Jersey – Planet…. The available information doesn’t establish that the standard jersey shares the X’s fabric blend, anti-microbial treatment or performance claims.

How should you wash and dry the R-Core jersey?
The available product and source information provides no washing or drying instructions for the R-Core jersey. It doesn’t specify water temperature, detergent, washing cycle or whether the garment should be air-dried or machine-dried.
The listing describes polyester mesh and fade-resistant sublimated graphics, but those details don’t supply a care method 100% R-Core Long Sleeve MTB Jersey – Planet…. It would be a guess to turn the fabric or graphics description into specific cleaning directions. Check the garment’s care label or the manufacturer’s instructions before washing or drying it.
That leaves an ordinary but important gap for a buyer: the sources describe what the jersey is made of and some of its design features, but not how to maintain it. No available source confirms a particular routine for preserving the fabric or graphics.

What trade-offs should you expect in hot, cold, or wet conditions?
The R-Core listing describes polyester mesh with moisture-management properties, but it doesn’t report tested cooling or drying performance 100% R-Core Long Sleeve MTB Jersey – Planet…. Cycle Gear says the polyester weave wicks moisture to help keep skin dry and prevent chills; that is the retailer’s description, not a measured result in the available sources 100% R-Core MTB Jersey (SM).
There’s no source evidence here establishing that the standard R-Core jersey is waterproof, insulated or proven to perform at a particular temperature. Mesh and moisture management may sound relevant to changing conditions, but they don’t answer how the jersey performs in rain, cold or heat. The available information gives no weather testing or quantified ventilation figure for this model 100% R-Core Long Sleeve MTB Jersey – Planet… 100Percent® MTB Gear – 100%.
Keep the R-Core X evidence distinct as well. A review describes that long-sleeved model as best suited to warm weather Best mountain bike jerseys 2025 – top-rated…. That observation is about the X, not the standard R-Core jersey. The sources don’t establish the same warm-weather suitability for this product.
Where can you buy the R-Core jersey, and can you verify authenticity?
The collection announcement said the Spring collection was available worldwide at the time, through 100% retailers and online at 100percent.com Video: 100% Announces the 2020 Spring Bike…. That historical announcement doesn’t confirm present-day stock. The Amazon listing records a price of $82.09 and says only one is left in stock 100% Rcore Mountain Biking Jersey – Down….
Other retailer information is also listing-specific. Planet Cyclery showed the yellow-black color in sizes S through XL as sold out or unavailable 100% R-Core Long Sleeve MTB Jersey – Planet…. Cycle Gear listed a black, size-small jersey with only one left and shipping within 24 hours 100% R-Core MTB Jersey (SM). These examples don’t establish what is available now across retailers or in other colors and sizes.
The sources provide no method for authenticating an individual jersey. A listing’s stock status, retailer name or product description doesn’t by itself verify the item’s authenticity. The available evidence supports checking the product and seller details shown with a particular offer, but it doesn’t support a definitive authentication test.
