Your new Impact suit was proudly manufactured from 100% NOMEX® (aramid) brand fiber.
The manner in which your new Impact driving or crew suit is cleaned and cared for is extremely important to the durability and integrity of the product through its life cycle. It is strongly recommended that your new driving or crew suit be laundered in lukewarm water with a gentle, neutral PH balanced laundry detergent (minimal acids or alkalis). Overly acidic or alkaline cleaning products can compromise elastics and fabrics. Certain chemicals and detergents can degrade the fire retardant materials used in the manufacture of this garment and can compromise the integrity of the suit or cause excessive shrinkage. Please read and follow all cleaning and care instructions contained in this manual and also on the care label of the driving suit.
• Prior to laundering, fasten the zipper, buttons, and all hook and loop closures to ensure these fasteners do not catch on the embroidery and adornments of the suit.
• Ensure the garment is inside out and affix the hook and loop attachments to protect them and other adornments from damaging the inner quilting.
• Impact recommends safety pinning the hook and loop attachments closed as an additional prevent against snags.
• Use a PH balanced (neutral) laundry detergent. Do not use chlorine bleach or chlorine based stain removers.
• Machine-wash your driving suit on a delicate or hand wash cycle in warm water (not to exceed 30 degrees Celsius, 86 degrees Fahrenheit).
• Tumble dry garment on low for a few minutes to remove excess moisture and hang to dry the remainder of the way.
• Always store your Impact suit away from direct sunlight as to avoid ultraviolet degradation of the garment’s fabric and materials.
Solvents such as Trichloroethylene (known as Tri-Chlor or TCE) are commonly used in dry-cleaning and can potentially damage the integrity of the driving or crew suit and / or cause the garment to shrink. Impact is not responsible for shrinkage or other issues that arise from improper care and laundering of your suit. While some shrinkage is normal over the course of the life of the garment, it is not enough to have an adverse effect on fitment. Improper laundering of Nomex threaded garments will cause excessive shrinkage. Most often associated with dry-cleaning, excessive heat during the wash or drying process is the most common cause and Impact will not be responsible for shrinkage. Customers returning garments to be altered due to shrinkage will be charged for the alterations needed to correct the suit back to its originally constructed size.
When affixing adornments, heat bonding should not be used and the garment should not be cut or otherwise altered.

Repair and Maintenance Instructions
Should the MasterCraft Safety / Impact driving or crew suit become damaged it is strongly recommended that the suit be replaced rather than repaired. Should the user wish to try and repair minor tears or abrasions, all repairs should only be conducted using the same thread and material that was used in the construction of the garment, by the original manufacturer.
It is recommended that only the original manufacturer of the garment make any repairs to the garment and/or its embroidery. It is recommended that all garments be inspected regularly for repair and maintenance. MasterCraft Safety / Impact assumes no responsibility for repairs and maintenance to our manufactured garments not performed by us.
Embroidery and Decorative Patch Instructions
The construction of the driving or crew suit, such as the sewing and seaming methods, are just as important to the integrity of the garment as the fire retardant materials used to manufacture the suit. Quilting of the inner liner to the outer layer is standard on all two-layer (and higher) MasterCraft Safety and Impact driving suits. The purpose of the quilting is to improve air circulation and to transfer heat at a slower rate and with less force and energy. The air pockets formed between each quilted stitch pattern delays the heat from being transferred to the body as quickly therefore it is important to preserve this protective air-layer by not penetrating the inner layer of the suit with embroidery or decorative additions. For this reason, MasterCraft Safety and Impact embroider only the outer layer only prior to final assembly of your driving or crew suit.
That being said MasterCraft Safety / Impact is one of the few manufacturers worldwide that can custom embroider only the outer layer of a suit prior to it being constructed together in final assembly. Only the original suit manufacturers have access to the outer most layer of the suit during its garment manufacturing process. To maintain the integrity of your suit, aftermarket embroidery and adornments should never penetrate the inner protective layer(s) and any additions to the garment should not interfere with its intended use and/or the thermal protection properties.
Should you require specific sponsor branding and similar adornments added to your suit after purchase, patches conforming to the ISO 15025:2000 standard for protective clothing are highly recommended. To maintain the thermal protection rating and overall integrity of the suit, MasterCraft Safety and Impact recommend that patches and badges should be manufactured from fire retardant thread and material (such as Nomex®) and should comply with the ISO standard 15025:2000. The patches and badges should also be affixed to the driving or crew suit using a fire retardant thread (such as Nomex®) and the thread should only penetrate the outer most layer of the driving suit. Glues and other adhesives (including iron-on methods) are highly flammable and should not be used to affix the patches or badges. The backing material of badges and patches should be flame-retardant and in conformance with the original intended purpose of the suit. When affixing adornments, heat-bonding should not be use and the garment should not be cut or otherwise altered.
Recertification of SFI 15 & 20 Rated Driver Suits
Inspection and recertification program for SFI 3.2 A/15 and SFI 3.2 A/20, driving suits manufactured by Impact.
Products covered: Any driving suit manufactured by Impact with an SFI rating of 3.2 A/15 or 3.2 A/20, manufactured on or after January 1st, 2010.
Suits will be inspected for eligibility of SFI recertification. Upon inspection if the suit is found to be eligible for SFI certification, it will be recertified and dated. If the suit is inspected and is not eligible for recertification, the suit will be rejected and the customer will be contacted with a full explanation of why the suit is not eligible for recertification.
Some possible, but not limited to, reasons a suit may not be eligible for recertification…
• Tears and/or separated seams.
• Contamination by flammable, unknown or any substance that may inhibit the suits ability to provide adequate protection.
• Improperly working closures, such as zippers or worn hook and loop fasteners.
• Knitted cuffs that are stretched excessively as to compromise a tight fitting seal and allow an entry point for heat, flame or flammable materials.
• Burn marks - Any suit found to have evidence of being involved in a fire will automatically be rejected and will not be eligible for recertification.
• Unauthorized modifications – Any suit that is found to have modifications not performed by Impact will be automatically rejected and not eligible for recertification.
In some instances, a repair may be available that will allow the suit to be recertified. If a repair is available to bring the suit up to specification, a quote will be given to the customer, and written customer approval will need to be received prior to any repair work being performed.
Cost of Inspection: $75.00, and includes full inspection of the suit, minor repairs (stitching-only, repairs of less than 1”, limited to 2 repairs per suit) and a new SFI tag with current date when applicable.
Suits must be sent in clean condition. Suits that are soiled/excessively-dirty will be assessed a $50 laundry charge or returned at the customer’s option.
