When you’re planning a trip with Rocky Mountain Whitewater Rafting, you’re probably asking the most common question we hear every season: what to wear rafting Colorado. It’s a fair question. Mountain weather changes quickly, snowmelt keeps rivers cold even on sunny days, and nobody wants to spend their adventure shivering.

The good news is this. Dressing for whitewater rafting in Colorado is simple once you understand a few fundamentals. We guide thousands of guests down Clear Creek every season, from first timers to experienced paddlers, and we’ve seen every outfit choice imaginable. Some work great. Some become funny stories at the takeout.

This guide will help you show up confident, comfortable, and ready for adventure. Whether you booked a beginner float or you’re eyeing Class IV rapids, here’s exactly what to wear, what to avoid, and what we provide.

Why What You Wear Matters on Colorado Rivers

Colorado rafting is different from floating a warm, slow river in the South. Our water comes from high elevation snowpack, especially on Clear Creek near Idaho Springs. Even in July, that water can be cold.

Proper clothing does three important things:

• Keeps you warm in snowmelt-fed water
• Protects your skin from sun exposure at high altitude ☀️
• Allows you to move freely while paddling

The right gear builds confidence before you even push off from shore. When you feel comfortable, you paddle stronger, listen better, and enjoy the ride.

The Golden Rule: Dress for the Water, Not the Weather

On the river, air temperature can be 80 degrees and the water can still feel icy. That’s why we tell every guest to dress for water immersion first, sunshine second.

Expect to get wet. Plan for it. If you stay dry, great. If you don’t, you’re already prepared.

Base Layer Basics: What to Wear Rafting Colorado in Warm Weather

During mid summer, when air temperatures are warm, your base layer is simple.

For most guests, this works perfectly:

• Synthetic athletic shorts or quick dry shorts
• A synthetic T shirt or tank
• Secure sandals with heel straps or old sneakers

Avoid cotton. Cotton holds water, stays cold, and takes forever to dry. That hoodie you love becomes a soggy anchor after one wave.

Instead, choose:

• Polyester
• Nylon
• Spandex blends
• Athletic performance fabrics

Think gym clothes, not beach clothes.

What to Wear on Beginner Trips

If you’re booked on one of our Beginner Trips, comfort and flexibility are key.

Beginner rafting options are perfect for families and first timers.

For these trips, especially mid season, most guests wear:

• Quick dry shorts
• Synthetic shirt
• Secure footwear
• Swimsuit underneath

In early season, when runoff is high and water is colder, we may recommend additional layers.

Wetsuits: When and Why They’re Required

Here’s where some guests relax immediately.

Wetsuits are required on all Intermediate, Advanced, and Full Day trips, and they are free of charge.

That means if you’re booked on:

• Intermediate Trips
• Advanced Trips
• Full Day Trips

You will be wearing a wetsuit provided by us.

No hidden fees. No surprises. We make sure you’re dressed appropriately for bigger water and colder conditions.

Wetsuits trap a thin layer of water between the suit and your skin. Your body warms that layer, which helps maintain core temperature even when splashed repeatedly.

For Class IV rapids and full day excursions, this added insulation is essential.

Layering for Intermediate and Advanced Trips

On our Intermediate and Advanced trips, the river gets faster, splashier, and more technical. You will get wet.

Under your wetsuit, wear:

• Swimsuit or athletic shorts
• Fitted synthetic top

Avoid bulky clothing under a wetsuit. Smooth layers fit best and stay comfortable.

For added protection, you can rent:

• Splash jackets for $3
• Wetsuit booties for $3
• Or both for $5

Splash jackets block wind and constant spray, which makes a noticeable difference during early season or cloudy days. Booties keep toes warm and protected inside the raft.

For experienced adventurers, this setup hits the sweet spot between performance and comfort.

Early Season Rafting: May and Early June

Runoff season is thrilling. Rapids are bigger, water levels are higher, and snowmelt is fresh.

Air temperatures might feel mild, but water temperatures are cold.

During this period, expect:

• Full wetsuit
• Splash jacket
• Secure footwear or booties
• Synthetic base layer

This is when preparation matters most. Our guides monitor river conditions daily, and we outfit you accordingly.

If you’re planning an early season trip, especially on intermediate or advanced routes, trust the gear system. It’s designed for safety and comfort.

Mid Summer Rafting: July and August

By mid season, air temperatures rise and river levels moderate.

On beginner trips, many guests wear:

• Athletic shorts
• Quick dry shirt
• Swimsuit
• Secure sandals

On intermediate and advanced trips, wetsuits remain required for consistency and safety, even if the sun feels warm.

High altitude sun can be intense. Bring:

• Sunglasses with strap
• Sunscreen
• Hat that fits under helmet

Protecting your skin matters just as much as staying warm.

Late Season Rafting: September

Fall rafting in Colorado is underrated. Fewer crowds, crisp air, golden aspens along the canyon walls.

Temperatures can fluctuate, so layers matter.

We often recommend:

• Long sleeve synthetic base layer
• Wetsuit for intermediate, advanced, and full day
• Splash jacket if windy

Morning trips may feel cooler than afternoon departures.

Footwear: What Works and What Doesn’t

Your feet will get wet.

Best options:

• Secure sandals with heel strap
• Old athletic shoes
• Wetsuit booties

Avoid:

• Flip flops
• Crocs without straps
• Bare feet

Secure footwear protects your toes during launching and landing and keeps you stable in the raft.

What Not to Wear Rafting in Colorado

This list saves discomfort later.

Avoid:

• Cotton sweatshirts
• Jeans
• Heavy hoodies
• Jewelry
• Anything you cannot afford to lose

Rings and bracelets can catch on equipment. Phones can fall into the river. Keep it simple.

Accessories That Make a Difference

Small details improve the day.

Consider bringing:

• Sunglasses with retention strap
• Waterproof sunscreen
• Lightweight towel for after trip
• Dry change of clothes for the drive home

Leave valuables in your vehicle. We focus on the river.

Addressing Common Pre Booking Concerns

Many guests hesitate before reserving because they’re unsure about clothing or weather.

Let’s clear those up.

Concern: I’ll be too cold
Reality: Wetsuits are required on higher level trips and provided free. Splash jackets and booties are inexpensive add ons.

Concern: I don’t own outdoor gear
Reality: Athletic clothing works perfectly. No need for specialized equipment.

Concern: I’m not experienced
Reality: Our guides walk you through everything. Proper clothing helps you feel confident from the start.

The goal is simple. You show up ready. We handle the rest.

What to Wear for a Full Day Trip

Full day trips combine adventure with endurance.

You’ll wear a wetsuit and likely benefit from:

• Fitted base layer
• Splash jacket
• Booties
• Sunscreen reapplication at lunch

Longer exposure means smart layering pays off.

Hydration and comfort go hand in hand with proper clothing choices.
