Just as it sounds, a custom-fit cover is going to perfectly hug every contour of your machine. This is the “like a glove” fit you’ve been looking for, and these covers are guaranteed to stay put over time, so you don’t have to worry about shifting and bunching. Features to look for include elastic hems, straps, and grommets for tying these down snugly. Quality custom-fit covers protect better because they don't flap in the wind (flapping causes abrasion damage and wears covers faster) and don't allow water pooling in loose material.
Semi-custom or size-based covers (small/medium/large/XL sizing based on machine dimensions) provide better fit than truly universal designs at lower cost than fully custom patterns. They work well if your machine dimensions match the size range properly. Verify length, width, and height specifications. Universal covers use one design to fit multiple machines, relying on elastic edges and adjustable straps for fit. They're most affordable, but fit quality suffers due to excess material, improper positioning of features, and potentially inadequate coverage or too-loose fit.
For long-term outdoor storage, a custom or semi-custom fit justifies premium pricing through better protection and longer cover life. For occasional or temporary storage, universal covers work adequately at significant cost savings.
UV exposure is a primary cause of cover degradation, and the damage that covers are supposed to prevent. UV-resistant materials include inhibitors in fabric composition or coatings that slow UV damage. To be clear, you definitely want your cover to expressly state that it comes with UV protection. Not as a footnote or a half-baked claim, but in clear language. This is backed up by the type of material it's made with: marine-grade or outdoor fabrics are going to give you far better UV protection.
Color is also a major deal when it comes to UV protection that surprisingly goes overlooked. If you want to hide dirt better, you can go with darker colors and be better off. Lighter colors will cut down on heat absorption.
And finally, don’t forget to look for that warranty! A high-quality UTV cover should come with a warranty against UV damage and/or failure of the material (like seams coming apart, etc.).
Covers that blow off in the wind provide no protection and can damage themselves or machines. Elastic hems (like fitted bed sheets) stretch over machine edges using tension to hold position. They work for mild conditions but can blow off in strong winds. Grommets and tie-down straps (straps threading through grommets and tying under machines or to tie-down points) provide more secure attachment, resisting wind. Quality covers include multiple tie-down points (6-8 minimum) positioned strategically.
Vents or air outlets in covers reduce wind pressure buildup. Without vents, wind gets under covers and lifts them like parachutes. Vents let air escape while preventing water or dust intrusion through mesh screening or overlapping flaps. Proper sizing matters too. Excessively large covers catch more wind and flap more, accelerating wear.
Should I cover my UTV if I store it in a garage or enclosed building?
This depends on storage duration and conditions. For short-term storage (days to weeks) in clean, dry garages: covering is optional, mainly protecting from dust accumulation. For long-term storage (months, like winter storage): covering even in garages protects from dust, temperature fluctuations, and moisture. Covers also prevent accidental scratches from items placed near machines or bumped against them.
What about mildew and moisture under the cover?
Use breathable covers that allow moisture vapor to escape rather than trapping it. Avoid covering wet machines. Let machines dry completely before covering. If you can, get that machine elevated off the ground and use a moisture absorber on the inside.
How often should I replace my storage cover?
This varies significantly according to a number of factors, including the cover itself, the climate your vehicle is kept in, and how often you use it. In harsher conditions, you may need to replace every one to two years, but with a really nice cover and gentler or more moderate conditions, you may get up to five years or more before damage begins showing.
