What it is made of
Brushless fan
Runs quiet enough to leave going in a truck cab overnight.
Flexible tubes2 × 610 mm
Reach the toe box, which is the only part that matters.
The full description
Most boot dryers are a heater. Heat above about 40°C is what breaks down the adhesives holding a boot together, which is why boots that live on a hot dryer delaminate a season early. This one moves a lot of air at 34°C instead.
It runs off a 12V socket, so it works in a truck between sits — the case where a dryer is actually worth carrying. Both tubes reach the toe box, which is the part that stays wet.
Bought for
Multi-day hunts out of a truck or a camper, and wet-country waterfowl.
Not for
Overnight use in a tent off a small power bank — 22 W will empty a 20,000 mAh bank in about four hours.
Field notes
- 01Pull the insoles and open the boot fully before you start. A closed boot dries in twice the time.
- 02Three hours in a cab between an evening and a morning sit is enough for a soaked boot.
- 03It works on gloves too — the tubes fit a gauntlet cuff.
