Why do Trident Drysuits not have a neck seal collar?
There are a number of reasons – “Bellows” seal with a conical, ringed neck. The bellows portion of a neck seal allows the user freedom of movement than a traditional tapered seal – if a collar is sown on to the drysuit to cover the seal it will immediately restrict the movement the wearer has. Also collars for most wearers can get in the way or rub/catch the chin.
