10 Models Reviewed in Depth
#1. Endura Hummvee Waterproof Short
You’ll get complete waterproof protection from the fully seam-sealed 2.5-layer fabric, making these shorts ideal for the wettest conditions. The extra durable stretch panels on the seat enhance mobility and longevity. The elasticated waist with shock cord ensures a secure, comfortable fit.
One caveat: the fabric may feel less breathable than non-waterproof shorts. They’re perfect for riders who face relentless rain and need dependable coverage. If you prioritize breathability over waterproofing, you might find these too warm.
Pros
- Fully waterproof
- Durable construction
- Comfortable fit
Cons
- Less breathable
- Limited pocket options
- Heavier than non-waterproof
Specifications
#2. Endura MT500 Spray Short
You’ll love the waterproof seat panel that sheds spray from your rear wheel, keeping you dry on wet trails. The PFC-free DWR finish on the rest of the short adds extra protection without harming the environment. The Clickfast compatibility lets you attach Endura liners easily for added comfort.
One caveat: the waterproofing is only on the seat, not the entire short. These are ideal for riders in damp climates who want targeted protection without the bulk of a fully waterproof short. If you need full coverage, consider a different model.
Pros
- Targeted waterproofing
- Eco-friendly DWR
- Clickfast liner compatible
Cons
- Not fully waterproof
- Limited pocket space
- Premium price
Specifications
#3. ARSUXEO Padded MTB Shorts
You’ll appreciate the built-in gel sponge pad that provides excellent shock absorption, making long rides more comfortable. The five pockets, including four zippered, offer secure storage for all your essentials. The water-repellent outer keeps you dry in light rain and muddy trails.
One caveat: the gel pad may feel bulky for some riders, and the shorts are not fully waterproof. They’re perfect for trail and road cyclists who want all-in-one convenience without needing a separate liner. If you prefer a minimalist shell, these might be too padded.
Pros
- Excellent built-in padding
- Plenty of pockets
- Water-repellent shell
Cons
- Bulky pad
- Not fully waterproof
- Limited color options
Specifications
#4. O’NEAL Mud Waterproof Shorts
You’ll get maximum protection from the 3-layer waterproof material, which keeps you dry even in heavy rain and mud. The durable yet lightweight design ensures comfort without sacrificing toughness. The waterproof pocket with zipper is a thoughtful touch for keeping your phone safe.
One caveat: the single pocket may be limiting for riders who need more storage. These shorts are ideal for wet-weather warriors and downhill riders who prioritize waterproofing above all. If you need multiple pockets, consider a different option.
Pros
- Fully waterproof
- Lightweight and durable
- Secure waterproof pocket
Cons
- Only one pocket
- Limited breathability
- Pricey for some
Specifications
#5. Nepest 2-in-1 MTB Shorts
The detachable dual-layer design gives you flexibility—wear the water-resistant outer alone or combine with the breathable liner for extra comfort. The 4D ergonomic padding absorbs impact effectively, making long rides more enjoyable. You’ll also appreciate the adjustable waist and silicone leg grippers that keep everything in place.
One caveat: the liner adds bulk, and the shorts may feel warm in hot weather. They’re ideal for trail and gravel riders who want built-in padding without sacrificing water resistance. If you prefer a minimalist shell, you might find the dual-layer overkill.
Pros
- Versatile 2-in-1 design
- Excellent padding
- Secure fit
Cons
- Can feel bulky
- Warm in hot weather
- Limited color choices
Specifications
#6. Loose Fit DH Shorts
You’ll enjoy the 4-way stretch fabric that provides full mobility for technical trails and aggressive riding. The water-repellent and quick-drying material keeps you comfortable in wet conditions, while vent zones at the waist and thighs enhance airflow. The adjustable waist with hook-and-loop straps ensures a secure fit.
One caveat: the loose fit may not suit riders who prefer a more streamlined silhouette. These shorts are ideal for downhill and enduro riders who need durability and freedom of movement. If you’re into cross-country, a tighter fit might be better.
Pros
- Excellent mobility
- Quick-drying
- Good ventilation
Cons
- Loose fit not for everyone
- Limited color choices
- No liner included
Specifications
#7. Mountain Bike Shorts
You’ll appreciate the water-repellent finish that sheds light rain and trail spray, keeping you drier on damp rides. The breathable fabric helps regulate temperature during intense climbs, and the multiple pockets offer convenient storage for keys, gels, or a phone. These shorts are a solid choice for everyday trail riding.
One honest caveat: the water resistance is not fully waterproof, so heavy downpours will soak through. They’re best for dry to mildly wet conditions and riders who prioritize breathability over maximum protection. If you ride in persistent rain, consider a fully waterproof option instead.
Pros
- Water repellent finish
- Breathable and comfortable
- Good pocket layout
Cons
- Not fully waterproof
- Limited color options
- No liner included
Specifications
#8. ARSUXEO Removable Belt Shorts
You’ll appreciate the removable wide belt that locks your waist in on rough trails and comes off for a clean everyday look. The water-repellent, quick-dry shell sheds light rain and dries fast, making them great for commuting. With four pockets, including two zippered thigh pockets, you can securely carry your phone and keys.
One caveat: the water resistance is not for heavy downpours. These shorts are perfect for riders who want one pair for both cycling and casual wear. If you need maximum waterproofing, look for a fully taped option.
Pros
- Versatile belt design
- Quick-drying fabric
- Good pocket layout
Cons
- Not fully waterproof
- Limited color options
- Belt may be extra
Specifications
#9. BERGRISAR Water-Resistant Shorts
You’ll love the soft stretch fabric that moves with you, offering all-day comfort on and off the bike. The breathable mesh panels at the waist and thighs enhance airflow, keeping you cool during intense rides. With five pockets, including side zippered ones, you have plenty of secure storage for essentials.
One caveat: these shorts do not include a padded liner, so you’ll need to wear cycling underwear for long rides. They’re perfect for riders who want a versatile short for mountain biking, hiking, or casual wear. If you prefer an integrated pad, look elsewhere.
Pros
- Comfortable stretch fabric
- Great ventilation
- Ample pocket space
Cons
- No liner included
- Water resistance is light
- Limited color options
Specifications
#10. ARSUXEO 1903 Shorts
You’ll get great value with these water-repellent shorts that are lightweight and breathable, perfect for a range of activities. The six pockets provide ample storage, including two deep hand pockets and four zippered ones. The adjustable waist with side tabs ensures a personalized fit.
One caveat: the water repellency is basic and may not hold up in heavy rain. They’re best for budget-conscious riders who need a versatile short for casual rides and outdoor activities. If you demand high-end waterproofing, invest in a more technical option.
Pros
- Affordable price
- Lots of pockets
- Adjustable fit
Cons
- Basic water resistance
- Not for heavy rain
- Limited color options

The Real-World Test for Waterproof Mountain Bike Shorts
A good pair of waterproof mountain bike shorts is the difference between a ride you finish and a ride you endure. Cheap options fail when it matters most—mid-trail, in a downpour, or after a creek crossing. This purchase deserves thought because the wrong fabric, fit, or closure system turns a simple piece of gear into a constant source of frustration. Here’s how to sort through the options without overpaying. For extra protection on wet trails, check our picks for the best knee pads for trail riding.
The Checklist That Separates Dry Riders From Drenched Ones
Waterproofing vs. water resistance
Not all “waterproof” shorts are created equal. Look for a fully taped seam construction and a membrane rating that actually blocks rain, not just light mist. If the brand only mentions a “DWR finish,” that’s a water-repellent coating—fine for drizzle, but it will wet out after prolonged exposure.
Breathability is non-negotiable
A waterproof shell that traps heat will leave you soaked from sweat, which defeats the purpose. Check for pit-zip-style vents, mesh-lined inner thighs, or a fabric with a high moisture vapor transmission rate. The best shorts manage both rain and perspiration without turning into a sauna. If you want to stay agile, our guide to lightweight mountain bike knee pads pairs well with breathable shorts.
Closure and adjustability
A secure waistband matters more than you think. Look for a ratcheting closure, hook-and-loop adjusters, or at least a sturdy snap with a grippy silicone waistband liner. You don’t want shorts sagging under a hydration pack or slipping when you’re pedaling hard through mud.
Pockets that actually work
Waterproof shorts with zippered pockets are useful, but check the zipper quality—cheap ones fail fast. Also, consider whether the pockets sit above your thigh’s flex zone. If they’re too low, they’ll bulge or chafe during pedaling.
Length and coverage
Trail conditions vary. A shorter inseam (10–12 inches) offers freedom of movement but less splash protection. A longer cut (12–14 inches) shields your thighs from rain and mud but can feel restrictive. Choose based on your typical terrain and riding style.
Sticking to your budget
You don’t need to spend premium dollars for a functional pair, but avoid the rock-bottom options—they often use non-breathable PVC coatings that crack and peel. Mid-range shorts from reputable outdoor brands usually offer the best balance of durability and comfort.
Mistakes Worth Sidestepping
- Confusing “water-resistant” with “waterproof.” If the product page says “showerproof” or “repels light rain,” it’s not built for sustained downpours. Read the fine print before you buy.
- Ignoring the liner. Some waterproof shorts come with a built-in chamois; others are meant to be worn over padded liners. Know which you’re getting—and whether the liner is removable for washing.
- Skipping the seam check. Run your fingers along the inside seams. If you feel rough stitching or see exposed thread, that’s a leak point. Taped seams are the only reliable barrier against water intrusion.
Locking In Your Best Waterproof Mountain Bike Shorts
If you want the ultimate foul-weather shell, the Endura MT500 is your pick—built for serious spray and abuse. For a lighter, budget-friendly trail essential, the Endura Hummvee nails all-day comfort. The ARSUXEO 1903 is the best all-rounder for riders wanting waterproofing plus a removable liner, while O’NEAL suits aggressive downhillers needing durability. The BERGRISAR is your value choice for dry commutes and casual rides. Every one of these fits a mid-range budget, so you’re covered without overspending. Don’t wait—check the current prices and stock via the buttons above before your next wet ride.
