Suunto Comfort Belt Service Kit


Rocksolid Guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, undergarments and swimwear excluded).

Really. If it's not up to snuff after you use it (a couple times) you can still bring it back.

It lasts longer than 30 days, but not forever. We'll be fair about it. We're all members here.

Price match guarantee

Found a better deal in Canada? Up to 30 days after purchase – we’ll match it.

If you see a lower price for this exact item advertised online, in print or in a store, give us a call at 1 (888) 847-0770.

If it’s identical, brand-new, in stock, and sold and shipped by a Canadian-based retailer, we’ll match that price.
