When you’re spending hours on the water fishing or a full day at the beach, your choice of shorts can make or break the experience. I’ve tested countless water shorts over the years, and the Columbia PFG Backcast IV keeps appearing in my rotation for good reason. But are they the right choice for everyone, or just another overhyped piece of outdoor gear?

After six months of testing these shorts in real-world conditions—from saltwater fishing trips to family beach vacations—I’ve discovered what makes them stand out and where they fall short. The marketing claims about sun protection and quick-drying performance are impressive, but how do they actually hold up when you’re sweating in the Florida sun or taking an unexpected swim?

This isn’t just another spec sheet review. I’ll walk you through exactly what it’s like to wear these shorts day in and day out, who they’re genuinely best for, and when you might want to consider alternatives instead.

Key Takeaways

• The UPF 50 sun protection is legitimate—I’ve worn these for full-day fishing trips without any sunburn through the fabric
• Dries faster than most board shorts but not as quick as premium technical fabrics—expect 15-20 minutes in direct sun
• The relaxed fit works well for active use but may feel too baggy for those preferring slim-fit styles
• Zippered security pocket is genuinely useful for keeping keys/cards safe during water activities
• Stain resistance is impressive—fish slime, sunscreen, and saltwater rinse right out
• Not the most compact for travel—these have more substance than ultralight alternatives

Quick Verdict

Best for: Serious anglers, boaters, and anyone spending extended time in the sun who needs reliable UV protection and practical features.

Not ideal for: Travelers needing ultra-compact gear, swimmers wanting minimal drag, or those preferring slim-fit styles.

Core strengths: Legitimate sun protection certification, thoughtful pocket layout, durable construction that handles abuse well.

Core weaknesses: Bulkier than premium alternatives, drying time could be faster, fit may be too relaxed for some.

Product Overview & Specifications

The Columbia PFG Backcast IV sits in the sweet spot between basic swim trunks and technical fishing apparel. While many brands focus on either fashion or pure function, Columbia manages to balance both with these shorts. The PFG (Professional Fishing Gear) line has evolved significantly, and this fourth iteration shows the refinement that comes from real angler feedback.

What sets these apart from generic swim shorts is the intentional design for extended outdoor exposure. The OMNI-SHADE technology isn’t just marketing fluff—it’s certified by the Skin Cancer Foundation, which matters when you’re spending 8+ hours in direct sunlight. The fabric weight (4.2 oz/yd²) strikes a balance between durability and comfort that I’ve found works well across seasons.

The 11-inch inseam provides good coverage without feeling like you’re wearing capris—a common complaint with some fishing shorts. Having tested these in sizes from Medium to Large (I’m 6’1″, 190lbs), I found the sizing consistent with Columbia’s typical fit. The Large gave me about 2 inches of room in the waist with the drawcord snugged, which is perfect for layering over swimwear or adjusting after a big lunch.

Real-World Performance & Feature Analysis

Design & Build Quality

The first thing you’ll notice is these don’t feel like cheap swim trunks. The fabric has a substantial hand feel that suggests durability, which has proven true through months of testing. I’ve snagged these on boat cleats, fishing gear, and rough surfaces without any tearing or permanent damage. The stitching is consistent throughout, with reinforced stress points at the pocket openings and waistband.

The relaxed fit is intentional, not lazy design. Unlike fashion-focused board shorts that prioritize silhouette over function, the Backcast IV gives you room to move. When I’m climbing in and out of a kayak or stepping up onto a boat platform, I appreciate the extra room through the thighs. However, if you’re used to slim-fit clothing, these will feel noticeably baggier than typical casual shorts.

The color options (Melonade, Vintage Blue, etc.) are practical for sun protection—lighter colors reflect more heat but may show stains, while darker hues offer better UV protection but absorb heat. I’ve found the medium tones strike the best balance for all-day comfort.

Performance in Real Use

Sun protection is where these shorts truly excel. During a recent 10-hour fishing tournament where the UV index hit 11, I wore these with sunscreen on my legs but not under the shorts. Zero sunburn or even redness—the UPF 50 rating is legitimate. The fabric doesn’t become significantly more transparent when wet either, which I’ve experienced with cheaper alternatives.

Drying time is good but not class-leading. After taking an unexpected swim while wade fishing, the shorts were comfortable within about 15 minutes in direct sun with a breeze. They’re quicker than cotton or heavy canvas but slower than premium technical fabrics like those used in Patagonia’s fishing line. The interior mesh liner dries slower than the main fabric, which can be slightly uncomfortable if you’re moving between water and land frequently.

The OMNI-SHIELD treatment makes a noticeable difference with stains. Fish slime, sunscreen, and salt residue rinse out easily without leaving permanent marks. After six months of use, my test pair still looks nearly new despite regular abuse.

Ease of Use & Practical Features

The pocket layout is genuinely thoughtful. The zippered security pocket fits a car key fob, credit card, and cash securely—I’ve tested this through multiple swims without any water ingress. The hand pockets are deep enough to actually use (unlike many swim shorts) and drain quickly when wet.

The adjustable waist system works better than most. The drawcord has just the right amount of friction—it stays put when adjusted but doesn’t require wrestling to tighten. I’ve found this essential for the relaxed fit, as it allows you to customize the waist without the bulk of a full belt system.

One limitation worth noting: the lack of a dedicated knife clip or tool loops. Serious anglers might miss these, though the pockets accommodate most small tools adequately. The shorts also lack the hidden pockets some fishing-specific brands include for pliers or other gear.

Durability & Long-Term Reliability

After six months of regular use—including saltwater exposure, machine washing, and sun exposure—the shorts show minimal signs of wear. The color has faded slightly (expected with UV exposure), but the fabric integrity remains excellent. The drawcord and zippers function as smoothly as day one.

The fabric’s resistance to pilling is impressive. Unlike some nylon blends that develop fuzz quickly, these maintain their smooth texture even after rubbing against boat seats and fishing gear. The seam construction has held up well, with no loose threads or weak points developing.

One area where I’ve noticed slight degradation is the water repellency. The OMNI-SHIELD treatment has diminished somewhat after 20+ washes, though the quick-dry performance remains unaffected. This is typical for DWR coatings and can be refreshed with products like Nikwax if needed.

Pros & Cons

What I appreciate:

• Legitimate sun protection that actually works for full-day exposure
• Thoughtful pocket layout with truly secure zippered storage
• Durable construction that handles rough use without damage
• Comfortable relaxed fit that doesn’t restrict movement
• Effective stain resistance for messy outdoor activities

Where they fall short:

• Bulkier than premium alternatives when packing for travel
• Drying time is good but not exceptional compared to technical fabrics
• Limited features for serious anglers (no tool loops, etc.)
• Fit may be too relaxed for those preferring slim styles
• Water repellency diminishes with repeated washing

Comparison & Alternatives

Cheaper Alternative: Generic Board Shorts ($15-25)

Basic board shorts from brands like Nike or generic Amazon options cost half the price but offer significantly less protection and durability. I’ve tested several, and they typically have thin fabric with questionable UPF ratings, flimsy stitching, and minimal features. The savings aren’t worth it if you need actual sun protection or plan to use them regularly.

Choose these if: You need occasional swim shorts for vacation and sun protection isn’t a priority.

Premium Alternative: Patagonia Wavefarer Board Shorts ($79)

Patagonia’s offering uses more advanced recycled materials with faster drying times (about 5-7 minutes versus 15-20) and better eco-credentials. However, they cost nearly twice as much and offer similar sun protection. The fit is slightly trimmer, which some may prefer.

Choose these if: Drying speed and sustainability are top priorities, and budget isn’t a constraint.

The Columbia Backcast IV sits perfectly in the middle—better quality and features than budget options without the premium price tag of technical specialists. For most people needing reliable water shorts, they represent the best value.

Buying Guide / Who Should Buy

Best For Beginners

If you’re new to water activities or need versatile shorts that transition from beach to town comfortably, these are an excellent choice. The sun protection is foolproof, and the durable construction means they’ll last through learning curves. The price point is accessible for those testing the waters (literally) without committing to specialized gear.

Best For Professionals

Guides, charter captains, and serious anglers will appreciate the all-day comfort and legitimate protection. While they lack some specialized features of premium fishing shorts, the reliability and practical design make them workhorse garments. I know several guides who rotate multiple pairs through the season.

Not Recommended For

Avoid these if: You need ultra-compact travel gear (they don’t pack as small as thinner alternatives), you’re primarily swimming for exercise (the drag is noticeable), or you strongly prefer slim-fit clothing (the relaxed cut will disappoint).

FAQ

How do they fit compared to regular shorts?
They run true to size but with a relaxed cut through the seat and thighs. If you’re between sizes, size down if you prefer a closer fit or stay with your regular size for maximum mobility.

Can you wear these as everyday shorts?
Absolutely—they’re versatile enough for casual wear. The fabric looks more like casual shorts than technical gear, and the colors work well off the water.

Do they float?
No, they don’t have buoyancy features. Like most water shorts, they’ll sink when saturated.

How many wears between washes?
With quick-dry fabric, you can typically get 2-3 wears if they’re just getting wet with clean water. After saltwater or strenuous activity, I recommend washing to maintain the technical properties.

Are they worth the price over cheaper alternatives?
If you need actual sun protection or will use them regularly, absolutely. The quality difference is significant, and your skin will thank you.
