Boss Therm Heated Glove Liner, 3 Heat Setting Control (low, medium, and high), one size, Soft Nylon 4-Way Stretch, Rechargeable, Black

[This review was collected as part of a promotion.] Boss 399-HG20 Heated Liner Gloves Review I picked up the Boss 399-HG20 Heated Liner Gloves for cold weather use, and after some solid testing, here's my honest take on them. Comfort & Fit These gloves fit snugly, which is great for a liner glove, but they do run a bit tight—so if you're between sizes, I'd recommend sizing up. The material is soft and flexible, making them comfortable enough for extended wear without feeling bulky. They work well under a heavier glove if you need extra warmth. Performance & Heating The 3.7V heating system does a decent job of keeping your hands warm, but don't expect blazing heat. The warmth is more of a subtle, consistent heat rather than an intense burst. They work best as a liner or for moderately cold conditions rather than extreme cold. If your hands get really cold easily, you might want something with a higher voltage or more aggressive heating zones. Durability Build quality is decent, though not the most rugged out there. The stitching and material hold up well with normal use, but I wouldn't put these through heavy-duty work without an outer shell for protection. The heating elements are embedded nicely, so they don't feel intrusive or stiff. Battery Life Battery life is just okay. You'll get around 2 to 3 hours on high and closer to 5 hours on low, which is about average for this type of glove but could be better. The batteries are lightweight, which is nice, but if you're out in the cold for long periods, you may want to bring a backup set. Charging time is reasonable, but I wish they lasted a bit longer on higher settings. Overall Verdict If you need a lightweight, comfortable heated liner glove for everyday cold weather use or as an extra layer, the Boss 399-HG20 is a solid choice. They perform well in mild to moderate cold but might not be warm enough for extreme temperatures on their own. Battery life could be better, but for the price, they do the job. If you're looking for something to wear while working outside or doing winter sports, they're a good option—just pair them with a good outer glove for added warmth and durability.

[This review was collected as part of a promotion.] These Boss Therm heated glove liner feel comfortable and sung, and they fit well when paired with a winter glove. It's the perfect way to enhance your warmth with the additional heat that the liners provide. I like that there are three heat settings which allow you to choose from warm to toasty, just depending on your preference. The charges hold up quite well and can provide a couple hours of use. While I like that the batteries have a thin profile, I do find it problematic if I'm wearing a watch as it adds considerable amount of bulk as it layers right over my watch and is a bit tight unless I remove my watch. Overall, though, a very comfortable and cozy liner can be used on its own or paired with a glove.
