Form meets function in our streamlined Loop Cap. Our vacuum insulated cap now features a lower profile design and new stainless steel easy-carry swivel loop. This cap merges looks and performance. The swivel loop is large enough to accommodate three fingers for a more comfortable carry and folds away when not in use. Insulated to prevent heat or cold loss, Loop Cap uses the New TK Closure internal thread design to form an all-stainless interior. That means contents never come into contact with plastic and stay hotter or colder longer. Compatible with all TKWide Kanteens, this workhorse of a cap won't leak or spill.
