Retrospec Comstock Youth Ski & Snowboard Helmet — Adjustable dial fit, EPS/ABS protection, removable earmuffs (Matte Blue Ridge)

No — this model does not include a rotational-impact system such as MIPS. The Comstock uses an ABS outer shell with an EPS foam liner and lists compliance with EN 1077:2007 Class B, but the product features and description do not list MIPS or any similar rotational-impact technology.

We don’t publish size‑by‑size weights on the official product page. Retailer specifications for the Comstock show the helmet weighing roughly 450–500 g (about 1.0–1.1 lb), so the Youth (52–55 cm), S/M and M/L sizes will be very similar in weight (around 1.0–1.1 lb).

Official Retrospec product page (sizes listed) plus multiple retailer/spec pages reporting item weight (Desertcart, Ubuy).

We do not include built-in speaker pockets or integrated Bluetooth in the Retrospec Comstock Youth Ski & Snowboard Helmet — the product listing only notes removable fleece-lined earmuffs and does not list audio pockets or integrated speakers. The earmuffs are removable (they slide off the straps) and are hand-washable, so some people fit very slim aftermarket speaker pods at their own discretion, but the helmet is not designed or guaranteed to accommodate speaker modules.

We don’t have a vent-shutoff — the Comstock’s vents are fixed open and cannot be closed. It features 10 vents with a moisture-wicking mesh cap, and comes with removable fleece-lined earmuffs (hand-washable) you can use — or add a thin balaclava — for extra warmth on very cold or windy days.

Yes — the Comstock uses Retrospec’s ErgoKnob (rear dial) designed for quick, one‑handed fit changes and retailer/review notes indicate the dial is usable with thick winter gloves. Retrospec’s product pages and help docs describe the ErgoKnob but do not publish independent long‑term durability test results for the dial, so while owners commonly report it holds up in regular use, there’s no official lifecycle test to cite.

We follow Retrospec’s guidance: do not use a helmet that’s been involved in an accident — even if it looks undamaged, dispose of it and buy a new one. [1] Replacement liners/parts aren’t offered as a guaranteed self-serve item on the product page; Retrospec asks customers to contact them so they can check parts availability (the Comstock does have removable, hand-washable earmuffs, but replacement parts aren’t listed online).

We recommend the Youth OS (52–55 cm) for roughly ages 5–8 years; this falls into the medium/youth range on Retrospec’s kids sizing chart. Example head circumferences you can expect by age (approx.): 4 yrs ~50–51 cm, 5 yrs ~51–52 cm, 6 yrs ~52–53 cm, 7 yrs ~53–54 cm, 8 yrs ~54–55 cm — measure around the widest part of the head (just above the eyebrows) and pick the size that matches the centimeter measurement rather than age. The helmet’s rear dial lets you fine-tune the fit within that 52–55 cm range.

We recommend hand-washing the removable fleece ear pads only — Retrospec lists them as “hand wash only,” so do not machine-wash them (even on a gentle cycle). After rinsing, gently press or towel out excess water and air-dry completely away from direct heat or sunlight; do not tumble-dry. [1] [2]
