Wonder Grip WG-338 Thermo Plus: Cold Weather Work Gloves That Actually Work Below Zero

The WG-338 Thermo Plus combines 100% waterproofing with cold resistance down to -20°C while maintaining touchscreen compatibility — a combination that’s harder to find than you’d think. These 13-gauge brushed acrylic lined gloves use double-coated latex (fully dipped except wrist) to create a barrier that keeps your hands functional when Montana temperatures drop below zero.

The standout feature? Wonder Grip Technology provides up to 58% higher friction on latex compared to standard coatings. That’s not marketing fluff — it’s the difference between holding onto frozen materials and watching them slip through your fingers.

Cold Weather Performance and Protection Ratings

The EN511 X21 rating tells the real story: these gloves maintain flexibility down to -20°C. That Contact Cold Resistance Level 2 rating means you can handle frozen materials without your gloves turning into rigid claws. The 13-gauge brushed acrylic liner provides thermal insulation while keeping enough dexterity to operate power tools.

Specification	Rating	What It Means
Convective Cold	X	Not tested for air movement
Contact Cold	2	Handles frozen materials
Water Penetration	1	Waterproof barrier confirmed
Temperature Range	Down to -20°C	Works in Montana winters

The gloves also carry EN407 heat resistance with contact heat resistance up to 250°C. Practical translation: you can grab a hot pipe or touch welding equipment briefly without melting the latex.

Waterproofing, Grip, and Cut Protection

The double latex coating creates 100% waterproof protection — not water-resistant, actually waterproof. Wonder Grip Technology delivers exceptional grip in dry, wet, and oily conditions. The latex extends fully around the glove except at the wrist, where the acrylic liner provides some breathability.

Safety Rating	Value	Protection Level
Abrasion (EN388)	2	Moderate wear resistance
Cut Resistance	X	Not rated (old test)
Tear Resistance	4	Excellent tear protection
Puncture	1	Basic puncture resistance
ISO Cut Level	C	Mid-range cut protection

The EN388:2016 rating of 2X41C puts these gloves in the middle ground for cut protection — enough for handling sharp materials but not for dedicated cut hazards. The Level C cut resistance beats standard latex dipped gloves but won’t replace dedicated cut-resistant gloves for metal work.

The high-visibility orange color meets site safety requirements, and more importantly, touchscreen compatibility means you don’t have to remove gloves to use devices. That matters when it’s -10°F and you need to check plans on a tablet.

Frequently Asked Questions

Q: Can these gloves handle Montana’s coldest construction days?

With cold resistance down to -20°C (-4°F) and maintained flexibility below freezing, they’ll handle most winter construction work. The limitation is the convective cold rating wasn’t tested, so extreme wind chill might reduce effectiveness.

Q: Are they actually waterproof or just water-resistant?

These gloves are 100% waterproof with double latex coating. The latex covers everything except the wrist area, creating a liquid-proof barrier that keeps hands dry in wet conditions.

Q: What sizes are available at Western Building Center?

The WG-338 comes in Small, Medium, Large, and X-Large sizes. Size 10 (X-Large) fits a hand circumference of approximately 10 inches excluding the thumb.

Q: How do they compare to standard winter work gloves?

The combination of double-layer waterproofing with thermal insulation in a flexible 13-gauge design provides superior dexterity at sub-zero temperatures compared to standard bulky winter gloves. Most winter gloves sacrifice grip or dexterity for warmth — these maintain both.

Q: What’s the warranty situation?

No specific manufacturer warranty duration is listed. Standard retailer return policies (typically 30 days for unused items) apply. Manufacturer quality guarantee covers defects in materials and workmanship.
