Eric Henrickson wrote a review of Hestra Heli 3-Finger Glove on January 17, 2011
The quality of the construction of these mitts is excellent, The design is lacking
As a trigger finger mitt configuration, Hestra went and designed a five fingered liner, which greatly decreases the warmth of the mitten.
The leather palm is unlined, and therefore NOT WATERPROOF.
As great as the three fingered (trigger finger) configuration is for warmth and dexterity, Hestra has overlooked these two design flaws, rendering their product less than adequate.
